Solar Orbiter Snaps Closest Pictures Ever of the Sun – Reveals New “Campfires” Phenomena
With summer here. Most of the news about our home star. The sun most likely will involve sunscreen right And that's something we should all be paying attention to. But scientists are also paying close attention to the surface of the sun, because despite it being so ever present, we still have a lot to learn about the sun. And they have just announced that the solar orbiter a satellite orbiting the sun has just sent back Some photos of surprising events on the sun's surface. Here to talk to us about these new images is Aneke to Groove instrument operation scientists for these solar orbiter she's based in Madrid, Spain, and joins us today. By Skype. Welcome to science Friday. No, I believe that these are the closest direct images of the sun's surface. Is that right? That's correcting the There has never being cameras actually observing the sum from that close, So we have had satellites going closer, but never with images never with telescopes. So tell us this being a radio program when you looked at those images. What air So what was that surprising thing you saw on the surface of the sun? Well, so first. We were really excited to see these first images because these are really the very first day that we got from the satellite. S so it's even just test images still, but we could already see new features. So about what we saw, Mamie was in the B imager. So that is a telescope that is looking at the Somme in extreme ultraviolet light. You cannot see that from worth because the atmosphere is blocking it. But we can see it from space. And so there you see part of the atmosphere that some the solar Corona and that atmosphere is currently very quiet. There's not that much activity on the sun. But now it turned out when we're resuming in that we see very little eruptions, which are much, much smaller than the ones we can usually see. And so this was quite a surprise because we have never seen these features before. And they were called campfires. If I'm reading this correctly, yes, because indeed they looked like this little flashes or flames off off light on DH. Actually, they they look like the many, many brothers ofthe solar flares and solar flares are much bigger eruptions off. Off radiation from the sun, and sometimes they also cause clouds ofthe solar plus muscle solar material That leaves the sun and so this thing to be And micro thin air. So to state so very small eruptions. That's kinda interesting. Do we know anything about Thies? Small eruptions? Ah, and how do we study these further? Well, so that's one of the strength ofthe solar orbiter that he does not only have these camera either has many different telescopes in total six, which will all observe the son of different wavelengths, so you see slightly different temperatures on the sun and slightly different lives. So the next bit will be to analyze these new features. In all those different types of light tto find out what exactly is happen and then we also have sensors which are measuring the environment on the spacecraft. And they can see what's actually coming out of the sun. So the effects ofthe these little activity on the environment of the sun and later also on Earth. So tell me, though, What mysteries you are most interested in and finding out more. About what? What keeps you up at night? Well, One thing that we are really excited about is that Salaam better will also look at the solar poles. So the North Pole and this house full of the sun, and we have never ever seen this before. We also don't know whether there's any activity going on there or how to some structure at these north and South pole, and this is important to wonder. Somehow, all these activity hurts. Because the sun has an activity cycles. It's not always as active. It has times several years where it's quite quiet, which is now the period we are in now and then we expect in two or three years from now there will be more solar activity. There will be some what we call solar storms. So this is the time when the sun is very exit, and then it will go back to a quieter stage. And we don't really honest that how that works, and we think that one of the keys Lie with the solar poles. So that's the part I'm most excited about. You know, I never thought about the sun having polls. I know that the Earth has polls. What creates the poles on the sun? Also, when I talk about poles, I talk mainly about the magnetic poles. So the son has a magnetic field while the earth magnetic things one me the North Pole and assess full But on the sonnets are much more complicated because there's magnetic field gets completely tangled. And this is actually what causes the activity and what causes this cycle in food.
