03:08This telescope is being sited in Chile, one of the best observing places in the world.
03:13So we don't have to worry about the Scottish clouds that I sit under here in Scotland.
03:18And it's a very dry, perfect conditions in which to make these regular observations on repeat, night after night after night,
03:28para ver las cosas que están cambiando absolutamente todo en el cielo y no puedes hacer eso desde los telescopios que tenemos en el espacio.
03:58Así que vamos a ver las cosas que están cambiando, así que vamos a ver las cosas que están moviendo, así que es muy importante.
04:19One of the first top science priorities for this mission is to map out all of the asteroids in our universe, to map their path, their trajectory, and hopefully, fingers crossed, we won't find any on a direct collision course, but if we do, that's when we start mobilizing the Planetary Defense Force, which is already in play.
04:39We've already managed to deflect an asteroid out in space. That was the NASA DART mission that happened a few years ago.
04:46Astronomers and space scientists are working on how to deflect things if an asteroid is coming in our direction, but it's going to be the Rubin Observatory that spotters it, because it can see things that are moving across the night sky.
04:59We'll also see things that are changing in brightness, and there's a special type of star called a supernovae, that when it dies, yeah, sad, stars do die, but when this star dies, it dies in a spectacular fashion.
05:15And it shines incredibly bright. It outshines the light of its entire galaxy. And they're really special, these stars, because when they die, they always shine with the same brightness. So we can use them as a way to measure distances in our universe.
05:45Whenever we look at the universe in a new way, we always discover something that we've never thought about before, and that's what we're super excited about, that completely new dimension of looking at the universe, not just through space, but also how it's changing through time.
