"Two it gary and now it's back to our show. This is space time with stewart. Gerry nashes antimatter. In cosmic ray detector aboard the international space station passed the major milestone celebrating ten years in orbit the alpha magnetic spectrometer. Am is technically the amos to which is matter on external trust of the orbiting. Outpost is a key instrument in scientists ongoing search to understand the mysterious invisible substance known as dark matter that matters really important makes up over eighty percent of all the matter in the universe. Scientists have no idea what it is. They know it exists because they can see its gravitational impact on normal matter such as holding galaxies together as they rotate brought up to the space station. One of the final space shuttle flights the magnetic spectrometer to was installed on may the nineteenth twenty eleven for initially plan mission of just three years observing cosmic ray particles and the antimatter counterparts. As they bombard the earth data from those observations upsides has understand. If cosmic dark matter antimatter potentially exist in the us in large quantities as well as understanding the origin and propagation of cosmic ray particles across the milky way galaxy. These data may also hopes side has better understand radiation risks of future crew missions both to the moon and mars as these cosmic rays can be harmful to humans led by nobel laureate samuel tink from the massachusetts institute of technology. The is collaboration. Involves some six hundred physicists. Engineers and technicians from sixty nations amos to survey collected data from over one hundred and seventy five billion cosmic ray events nashes amos project manager. Ken bulwark says. Data from the aim is to is rigorously. Filtered keeping list than one in two thousand la vents initially recorded as cosmic rays enter. The aim is to not all of them travel through each of the instruments nine eight detectors and if a cosmic ray particle fell three measured by. Oh nine detectors. It stater isn't stored even with its robust filtering. Aimez collects and stores dead from sixteen billion cosmic. Ray events annually boeing says. Ams is also looking for antimatter. Prison inaccuracies of parts per billion a massive experiments detected antimatter in the form of anti protons and pasi drones. Anti protons are the negatively charged antimatter counterparts to positively charged. Protons positron 's are the positively charged at hematic pads to negatively charged electrons amos to is allowed scientists to determine the different types of geophysical sources such as dark matter in cosmic ray collisions produce high energy positons as opposed to those which produce high energy electrons providing insights into the origins of these opposite particles. Other aim is to research has looked at the unique differences in positron electron activity at different energy levels. The findings have already led to the publication of more than seventeen scientific papers which themselves being referenced by literally hundreds of other papers and scientific research articles this report from this tv. Humans have observed many wonders across the cosmos yet. Much of our universe is still shrouded in mystery. Among those mysteries is the formation of our universe. Which should have resulted in a balance of matter and its corresponding counterpart eddie matter. Much of that matter is thought to exist in the form of dark matter which can't be directly observed much of the antimatter can't be found at all studying fundamental particles originating from sources up to billions of light years away may hold the key to understanding both the composition and history of our universe. Welcome to the world of particle physics. Currently being explored for low earth orbit by the alpha magnetic spectrometer installed on the international space station or iss planets stars interstellar gas dust but were able to observe a cross. The universe comprises less than five percent of the total content found throughout the universe the other ninety five percent. He's dark dark matter as well as dark. Energy dark matter doesn't interact with or produce light as far as we know it doesn't consist of normal matter or matter that can be observed directly. So how do you improve understanding of something. That can't be observed. One way is to look for evidence of its interactions. Kurt castillo the assist program at johnson. Space center explains how the giant magnitude of ams. Oh two is working to help. Scientists test and modify their theories. Scientists are using ams. Oh to to look at cosmic rays charged particles that travel near the speed of light. Ams o to categorizes each cosmic ray looking at a high energy range to see whether that stellar phenomena that we can measure can account for all of the cosmic rays. We're seeing but if you see something in the spectrum that doesn't fit then this could be evidence of dark matter. Interactions by studying cosmic rays. Scientists are also able to search for antimatter. The big bang theory of the universe's origin requires a fifty fifty ratio of matter to antimatter but to date. The amount of antimatter. Found doesn't come close to matching the amount of matter known to exist. Castillo says one of the goals of the mission is to detect antimatter and see if there are any large collections of it out there somewhere when particles pass through the strong magnetic field produced by ams oh to their paths bent. Antimatter particles standout because their paths bent in the opposite direction compared to matter particles the instruments searches for antimatter with the sensitivity. Three orders of magnitude greater than the original ams which flew in spacing june of nineteen ninety eight aboard the space shuttle discovery. This could support the discovery of antimatter. Pools that were previously. Undetectable a key factor in our ability to get the most out of ams. Oh two is time originally expected to have a life span of.

Now, as we mentioned last time I've been checking out a fascinating 'cause looking at how science shapes science fiction as usual with the great courses plus Electra is top notch. It's presented by Dr, Charles. A professor of physics and importantly a lifelong science fiction fan he's the author of the book was Aliens and Star Ships, physics and maths in fantasy and science fiction. The cost explains how really good science fiction comes out of really good science. You'll also learn how science fiction through the ages has helped shape scientific discovery. This is a really great cause but then again, that's what the great courses plus is all about and because it's a streaming service, you can use the great courses plus APP to educate yourself anywhere any time, and now is the perfect time to sign up for the great courses plus as a space time listener, you can check at any causal lecture and.

This is space time with Stewart Gerry. Necessary transiting EXOPLANET survey satellite tests is providing astronomers with a new view, the northern skies revealing panorama of both million stars and newly discovered worlds. The putter hunting spacecraft is now in seventy, five percent of the sky during its two year. Long survey included in that has been the discovery of seven four never before seen exoplanets wields beyond our solar system astronomy securely sifting through the test data looking at additional twelve hundred planet candidates. Tests locates planets by simultaneously monitoring entire sector of stars all at once searching for tiny total changes in the brightness of the light coming from any one of those thousands of. Stars. That dip in brightness repeats on a regular basis, it could be caused by opening planet passing in front of Translating The star. As seen from the spacecraft's perspective, this technique is proven to be the most successful planet finding strategy set fire accounting for some three quarters of the nearly forty three, hundred, six planets now known. The data collected by Tis also hopes in the study of other phenomena, such a star variations and sipping never explosions and unprecedented Tito, the new just released northern those AAC cavs Elissa. This guy than it southern counterpart, which was image during the mission's first year of operations, and for that, half the northern sectors team decided to angle the cameras further north to minimize the impact of scattered light from the Earth and the moon resulting in what's out to be a product gap in the coverage. Still this new northern Panorama is spectacular yet it only represents a glimpse of the day two tests returned. The mission splits eight celestial hemisphere into thirteen sectors. Test Image date sector for nearly a month using four cameras h carrying a total of sixty cents isn't that as charge coupled devices or CCD's. During its primary mission, the cameras captured a full sector of the sky every thirty minutes this means eat CCD acquired nearly thirty, thousand, eight, hundred full science images. Adding another measurements means tests now being back more than forty terabytes of data equivalent of streaming, some twelve thousand high definition movies or an average weekend viewing my place and these numbers will rise shop over the next year is test begins its extended mission. This will see the space telescopes spin another year imaging seven sky the probe will revisit planets discovered. During its first year of operation also find new ones and filling gaps in coverage from its initial survey improvements to the spacecraft steady collection and processing now allows us to return full sector of images every ten minutes, and he commissioned the brightness of Stars every twenty seconds all while continuing previous strategy of measuring the brightness of tens of thousands of stars. Every ten minutes this report from this TV tests. The transiting exoplanet survey satellite has completed its survey of the northern sky marking the end of its primary mission. To do this test divided the northern sky into thirteen sectors and it's four cameras monitored each sector for nearly a month. With these extended views test looks for slight dips and starlight when distant planets pass in front of their host stars. But it also caught short lived events such as a black hole tearing apart a star that wandered too close. It took a full year of tests imagery to build this beautiful panorama of the northern sky. A large swath of the northern sky remains unmapped for six sectors test tipped. It's cameras further north to avoid regions where stray light from the earth and the moon would hamper the view. At the center is the continuous viewing zone here, the view of one test camera labs across all thirteen sectors, which means test monitored the region for nearly an entire year. At its center is the North Ecliptic Pole. This is where the imaginary axis of Earth's orbit around the Sun needs the sky. More familiar too sky watchers is the North Celestial Pole. This is where the north end of our planet's spin access Intersex the. Sky. The whole star vault appears to revolve around this point conveniently marked by the nearby. Star Polaris. Located about thirty seven light years away in the Constellation. Boat Teas are tourists is the fourth brightest star in the night sky. New Stars form in gas-rich clouds throughout our galaxy. The North America Nebula named for its resemblance to the continent is a prominent example. Located about seventeen hundred light years away in the Constellation cygnus. It's part of a vast factory complex with enough gas to make one hundred, thousand sunlight stars. Peering beyond the confines of our own galaxy test image, the closest neighboring spiral galaxy. Visible by eye as a hazy patch, the andromeda galaxy located two point five, million light years away is a city of stars as vast as our own Milky Way. Astronomers have just begun sifting through the torrent of test data and are working to confirm planets among the thousands of candidates identified by the mission far.

And you study suggests that material from the main, though at asteroid Vesta is being discovered on the surface of the near Earth Asteroid Banou the new findings reported in the journal Nature Astronomy a based on observed by Nassar's Cyrus. Rick spacecraft which is being studying the four hundred ninety five meter wide Apollo Group asteroid for the past two years Cyrus Rix was in two, thousand sixteen the spacecraft is studying the evolution composition and characteristics of this carbonaceous rubble. Pile asteroid as they carried out their observations straits not six boulders ranging in size from two to five meters scattered across new Southern Hemisphere near the equator, which appear to be some ten times brighter than the rest of Banou and when they undertook more detailed spectroscopy measurements found the signatures which included pyroxene suggest to these particular boulders didn't come from Banou but from another asteroid Vesta located in the somewhat more distant main asteroid belt between Mars and Jupiter. A spectrometer separates light into what's component colors, and since elements and compounds have distinct Sigma Japan's in Brighton dark across a range of colors they can be identified using a spectrometer and the signature from the banana bowl. This was characteristic of the mineral Pyroxene, which is similar to what seen on Vista. Now, the leading hypothesis to try and explain the observations is that Banou, inherited the material from its parent asteroid body after a vista would that's a fragmented? By Vista collided. With. Bananas Parent Body, sometime in the distant past. Then Win the newspaper and body asteroid was destroyed in another collision a portion of its debris accumulated under its own gravity to form Banou including some of the pyroxene from Vesta astronomers don't think the boldest formed them.

The new results sheds light on the intricate orbital dance of asteroids on the violent origin of. which is a rubble pile asteroid that coalesced from the fragments of a massive collision. Six boulders ranging in size from five to fourteen feet were discovered scattered across venues, Southern Hemisphere, the equator, these boulders are much brighter than the rest of Bennett with some appearing as much as ten times brighter than their surroundings. The unusual boulders on. Benny. I caught the teams I in images from the Cyrus rex cameras, instrument, the signature from Boulder. So as characteristic of the mineral seen from Vesta and the vest. Smaller asteroids that are fragments blasted from VESTA. When a sustained significant asteroid impacts, the team tested a few different theories to determine the origin of these folders I. It's possible that the boulders were originally part of been or its parent body. However, this is unlikely based on how pure scene is created. This mineral typically forms when rocky material melts at high temperature. Benue. Is composed of water bearing minerals. So it wouldn't have experienced very high temperatures in its history next the team considered localized heating. Perhaps from an IMP, the scale of impact needed to create large boulders is much more significant than what is expected to take place in the main asteroid belt. So the team ruled out these scenarios and instead considered other pyrrhic seen rich asteroids. That might have implanted this material to Benue for its parent. This is possible because as asteroids move through the solar system, their orbits can be altered in many ways including by the pull of gravity from planets and other objects meteoroid impacts even the slight pressure from sunlight. The new result hubs pinned down the complex journey begnaud and other asteroids have traced through the solar system.

New Study suggests the earth solid in a core somewhere between one and one point three billion years old the findings reported in the journal Physical Review letters places the court. The younger end of an age spectrum usually runs from about one point, three billion to four point, five, billion years of age. But the Newark also exit a good bit older than another recent estimate of core, which suggests that it was only five hundred and sixty, five, million years old. The study's important because it hopes to pin down the magnitude of how the core conducts hate and the energy sources that power the planet's Cheer Dynamo Mechanism that Sustains Years Magnetic field, which keeps compasses pointing north and more importantly help showed life on the planet from the harmful of fakes of the solar wind and cosmic rays.

Hey, through conduction and thermal conductivity is key to determining a number of other attributes about the core including when the in Ecole owned over the years estimates for the cause age and conductivity have gone from very holden, relatively low to very young relatively high. These younger estimates have also created a paradox with a cool would have had to reach unrealistically high temperatures in order to maintain the dynamo of billions of years before the formation of the inequality for the new research. saw that paradox by finding a solution that keeps the temperature of the core within realistic parameters of course, finding that solutions dependent on directly measuring the conductivity of the eye on the coli conditions way precious a more. than a million atmospheres and temperatures can reach six thousand degrees. Celsius rivaling those on the service of the Sun Researches achieve these conditions by squeezing laser heated samples of mine between two diamond animals in the bar tree. Of course, that was no easy task taking more than two years of trial and error in order to get suitable results and yearly measured conductivity. It's between thirty and fifty percent less than the conductivity of the young chorus. And it suggested the dynamo was maintained by two different energy sources and mechanisms, thermal conviction and compositional conviction. At first, the GOP Dynamo was maintained by thermal convection alone bit now, H. Mechanism plays in equally important role. Lynn says the improved data on conductivity and heat transfer over time allowed him and colleagues to make more precise measurements of the age of the core knowing the hate flocks from the article to the lower mantle allowed the authors to consider win did the earth course sufficiently to the point where the inequality began at crystallize importantly, this revised age for the core could correlate with a spike in the.

There's a problem a big one because there's simply no debris from an Airburst. Airburst the thing is when they twenty meter wide media Eberstadt severence. Guys of children blinks back in two thousand thirteen fragments of the space rock were found scattered right across the landscape, even in a nearby lake, but other than those microscopic sized iron nickel grains. We talked about no fragments of the Tunguska Meteo ever been found certainly nothing comparable with shown the blends. And that's led some scientists to explore alternative causes. Now a new hypothesis in the monthly notices, the Royal Astronomical Society argued there fragments because the asteroid never fragmented instead it glanced off Earth, atmosphere and continued on through space, and that's not as revolutionaries it sounds media was have been nine to skip across the atmosphere, one example being the great daylight Bible caused by Space Rock, the size of a bus, which was saying glancing off the upper atmosphere by Utara Wyoming. In one, thousand, nine, hundred, seventy, two. The authors use computer modeling to explore several different scenarios looking at different size, meet yours travelling at different angles and different velocities. Eventually, they found that an I an asteroid about. In, size coming to within ten kilometers of the Earth surface at a shallow angle would have remained largely unscathed and would continue orbiting the sun. They claim that rabbit compression of nearly asteroid would have been enough to create the blast region observed to find out more entered. Ugly is speaking with astronomer Professor Fred Watson Siberian, Times. has come up with a new theory about how. How the at twin goose event originated bicycling that that thing that happened over one hundred years together flattened massive areas of Siberia with that that the shock wave of an asteroid impact now according to the Siberian Times another theory is that the asteroid didn't actually hit the earth. It skimmed the earth and went back out the other side of the atmosphere so. How close modern asteroids skim by without co without crashing into it, and all being pulled into the gravitational field, and how large is the size of the one that would skim earth versus those that often Pamela Planet on a daily by Bassus Yeah, that's I actually saw that article as well and I think it is a really interesting suggestion, so what prompts the suggestion that? Maybe it was something that basically grazed the skim through the atmosphere detonated probably but then the bulk of carried home on his journey through space. Space one of the reasons why people like us idea is that it's very hard to find any evidence of debris as a result of the Tunguska, event is no single crater. People have looked at the whole landscape around there is full of lakes and the reason suggestion of a lump of something at the bottom one of the likes, but nothing that would count for the eighty million trees that were essentially flattened by that explosion, which if I remember? It was one thousand nine hundred nights his. I think you mentioned earlier. So the if you postulate a grazing impact than Pecan, back the physics work, and apparently they do, you can neatly answer why this no mater is no asteroidal daybreak that has been found in the district, so how close my an asteroid skin by the without crushing into it and obeyed big into the gravitational field, so what it depends on is a spate of approach. You've got something going relative to the US. US Let me do a quick calculation here at less than about eleven kilometers per second than it will probably hit you because that s escape velocity, and it works back when foods, but most of these things are traveling much faster than that, because the ascorbic velocities thirty kilometers per second around the sun hand asteroids in obits that gives them a whole range of velocities as well so you might get things. Things up to seventy kilometers per second on the high end and ECON. Get things because he got the asteroid going in the same direction, so it all depends. If you have something going really high speed, then it will would skim through the atmosphere. will be slowed down by the atmosphere, but not really significantly that the phenomenon that we're saying with this object, so you get a interaction with the. The atmosphere explosive fund very likely to to coast debut on the ground, but the height that this would happen I'm guessing that you talking about high steady kilometers or something like that to the surface that while not would. If something was going fast enough, it would not be appreciably slowed down by the atmosphere, even that sort of debt, but it would cause a big object particularly would cause. Dramatic detonation of the allies at least so the thing about. The Patches Mrs good as a mile a missive. A five hundred kilometers. He's much better because it doesn't interact with the atmosphere despite call the toll, but if you've got something that penetrates deep into the atmosphere them, saying maybe closer to fifty kilometers, I think fifty kilometers. Disney assume talented. The explosion took Guscott than if it's going fast enough, it will keep on going once again. How big is the size well? It really is dependent on speed. What the size determines is how much it comes out the other side of the atmosphere. If it's big enough, then they'll be still. Something left to fly on back. Back in Soviet if it's smaller than I would guess you talking about fifty Mehta's or something of that size than you might get complete detonation and produce some debris on the ground, which is exactly what happened with the Chelyabinsk episode, where there was an explosion, thirty kilometers above the ground, and there's a daybreak field downstream of that the biggest landed in a like that thing didn't carry a hominid full bits around the some, but basically still to be about thirty twenty to thirty meters across the current situation with objects is NASA is working very hard.

Any study says the strange axis of rotation of the planet Uranus together with the unusual properties of its moons and ring system where most likely caused by an engine collision with another planet up to three times the size of the Earth billions of years ago the unusual attributes of the ice giant urine us have long puzzled scientists. You see all of the planets in our solar system orbit around the sun in the same direction and unruffled. The same plane called the ecliptic. Astronomy believe this characteristic is vestige of how our solar system formed in the first place from a spinning disk of molecular gas and dust. Some four point six billion years ago most of the planet's also revolve on the access in the same direction with a pulse or enter perpendicular towards the ecliptic plane. The exception he's Venus which slowly spins backwards with the Sun rising in the West and sitting in the East. Probably the result of mentioned tiny theory collision eons ago just is unique is the planet. Uranus Spin Axis is tilted to over ninety eight degrees now by comparison earth's axes total by just twenty three and a half degrees. So you and this is pretty well spinning on its side and just as the Earth Spin Axis. He's always pointed words. The same background stars in the sky the orbits around the sun thereby giving us over changing seasons. The spin of urinals is also pointed to the same position in the sky as it orbits around the Sun so as you're in a spins on its axis and orbits around the Sun. It appears to be rolling around in waddling from an Earth. Observe respective like all the planets urine as ring system and large collection of moons at least twenty seven at last count they will but the planet around its Equator. So they too are tipped over on this side now. It's generally believed that Earth God. It's been accessed tilted a giant collision four point five billion years ago when a mass is spinal cord theater slammed into the early. Proto worth that collision melted birth planets into a magma Russian which eventually solidified forming today's earth and bringing some ejected debris into orbit. Which eventually coalesce to form the moon. These massive collisions would have been fairly common in the solar system. In fact they're an important part of the story of how planets form and now a report of the journal Nature. Astronomy is explained how year and it's good. It's far more extreme.

Now, while we're on the subject of XM as the orbit is also measuring trace gases in the Martian atmosphere. Trace gases, occupy less than one percent of the atmosphere by volume and their require extremely precise measurement techniques in order to determine their exact chemical composition. The prisons of trace gases is typically measured in parts per billion by volume so for example, for earth Smith, an inventory measuring about eighteen hundred parts per billion by volume it means that for every billion molecules about eighteen hundred methane, methane is a particular interest for scientists because what it's often produce through geological processes, it can also be produced through biological processes, therefore making it a particular signature for life. In fact, some ninety five percent of all the methane in earth's atmosphere is generated through logical processes and because methinks quickly destroyed by solar radiation in the atmosphere. Any atmospheric detection of methane molecules implies that it must have been? Released relatively recently. Although it could have been produced millions or even billions of years ago and simply remain trapped in underground reservoirs. Until now the European Space Agency's Mars express orbiter detected methane on the red planet back in two thousand and four at the time indicating around ten parts per billion by volume Earth-based, telescopes voice detected mash and methane up to forty five parts per billion by volume and of course, Nassar's Mars curiosity Rover, which has been exploring Gail credit since two thousand twelve as detected between zero point two and zero point seven parts per billion of methane by volume with some seasonally higher level spikes. And of course, just last month, we reported that MAs express observed a methane spike just one day after curiosities highest level readings than your results from XM as provide the most detailed global analysis yet. However, it's only detected an upper limit of zero point zero five parts per billion by volume some ten to one hundred times less than any other observations. The most.

What we've learned from us Cap'n MWA, we'll be fading into the K design the two. Functions of what's being built in Australia, and what's being built in South Africa. You looking at different ends of the electromagnetic radio spectrum out you low frequency radio waves and winds looking at midway prince radio eight. Yeah. That's right. So they'll be complementary and what happens then once you collect that data. Somehow there's going to be an awful lot of data to try and process and determine what you want, and what you check out, and what you cave and Hetty dual letting witty store it. And how do you simply get that amount of data from one place to another as an S k- Tecom. Oh, absolutely data radio telescope producing masses more data than we've been used to radio. Astronomers Esca will have an archive that something like two three hundred PETA bytes of data year, so solving that big data challenge is one of the key things will be working on over the next year. That's the big problem isn't Hetty. You know, what you keep his worth keeping headed? You know, what you Chuck out stuff that you can afford to get rid of you can afford to lose. So that's a really key challenge. And for the first time with these telescopes the computers, the supercomputers that when the data were really part of the telescope because we have to process the data more or less at the same time as it's taken. We just can't afford to stole the data anymore in this curse. We're talking about a new generation of computers. Some of the biggest in the world. That's right. Look will require for k x o scale kind of computing. So they'll be those will be big computers than anybody has now. Fortunately, we've got a few years yet to get this is all being coordinated from Manchester England S K headquarters in Manchester. There were ten member countries all over the world, and we really very much enjoyed that international. Collaboration. In fact, in two weeks time, we'll be doing in Rome to sign the treaty fast. It's too syrup. His deputy director of SIA Sira, astronomy and space science,

"stewart gerry" Discussed on SpaceTime with Stuart Gary

"No better place to get everything back to school from a to z. These coast of New South Wales was witnesses, spectacular celestial show with a fiber streaking across the evening sky. The Meteo was saying as north as the Queensland Gold Coast right along the New South Wales coastline and as far south as Gibbs land. In eastern Victoria, the Meteo was witnessed by thousands of papal dash. Cam video showed the bluish, green fiber light up the dock and skies from the east apparently breaking bad as it traveled. It's apparent Brian. This suggests that this media could have been something between thirty and seventy centimeters wide, and it's blue green tail suggests the Meteo had an iron composition, and I in media is if they're lodge enough, can't survive atmospheric entry, making it all the way to the ground where they become meteorites. It's unlikely that this Meteo was out of the current Percy. It's media show which is picking this weekend per seats have radiant, which from somewhere like Sydney would be well to the northern horizon with best feeling occurring between midnight and dawn. This Meteo was seen at six thirty the evening scientists. Originally anyone with video the Meteo Doppler, the foul to the fibers in the sky app that will hope astronomers pinpoint its trajectory across the sky and where it may have come down this latest event follows. Last week's report of a big grain fi bull in north Queensland skies, saying by PayPal, in areas as far afield as MCI towns, filling cans, you'll listen to space time. I'm Stewart, Gerry..
