Suns, Hubbell, Adam Reese discussed on 60 Minutes
Ten thousand galaxies so every single point of light is an individual galaxy its own little island universe and so this is a real visualization of the, distances of these galaxies Three d like we're, flying through so we can make these, images three d because. We know how far away the galaxies are what, how will has essentially given us as, the size, of, the universe Hubble is hottest. That the universe is filled with hundreds of billions of other galaxies and now the latest analysis of Hubble's data reveals. There could be more than two trillion, galaxies, ten times more than previously fought typical galaxies like our Milky Way have one hundred billion stars that means the. Total number of stars or, Suns out there is. To followed by twenty three zeros. That's called two hundred six till you to get some sense of how many stars that is we went. To Adam Reese who, won a Nobel prize for. His work on Hubbell this is more stars in the, visible universe in grains of. Sand on the beach all the beaches on earth and Hubbell his show Shown us this. It has in many cases it has, allowed us, to see what some. Of the most distant galaxies look like and how many stars were in them and we've been, able to add it all up Hubble has been called a time machine. Said it looks back in time what has been the most astounding part of that. For you I study explosions of stars called supernova it's like fireworks it's only visible for a short period of time in this case a few weeks and that light has been travelling to. Us for ten billion years it began its journey when the earth wasn't even here and over those ten billion years our planet formed life developed we built the Hubble space telescope we open the. Aperture door and in the last one billionth of one percent of that journey that. The light made we opened the door just in time to catch it almost didn't, catch anything the first pictures sent back, were blurry Because of a microscopic flaw in the mirror the space. Agency launched a daring mission to fix Astronauts have. Made five trips to hobble to repair and upgrade its equipment later on you can open it there, will cover John Grunsfeld known as the Hubble repairman flew three of those missions to a telescope the size of a school bus orbiting three hundred miles. Above earth just about anything, that we can easily change and. Upgrade, and fix has been fixed the workings of the telescope. All of that has been transformed Yep it is like a new telescope on your. Last mission you come out of. The airlock and he's got this big smile on your face I thought I can't imagine. Anywhere I'd rather be outside the space shuttle in my spacesuit next to the Hubble space telescope I was just so happy Hubble has changed what we know about the universe it structure evolution it's, age thirteen point eight billion years Hubbell's showed us.
