NASA reports seeing the 1st confirmed alien object to enter Earth's solar system

[Music] [Music] it was a special day when this object was first discovered we have been waiting for the discovery of an interstellar object for decades basically oh and I first heard about this interstellar object it was very exciting just from a scientific point of view that finally there's been an actual observation of such an object this object is simply a piece of another solar system that was expelled and it has been traveling through interstellar space for hundreds of millions of years billions of years we don't know number of our survey projects and other observatories immediately turned their telescopes to take observations of this objects you the observations we have so far it looks like it's a very elongated object maybe about a quarter mile in length we think this object 2017 u1 is very long perhaps 400 meters or so long and very narrow skinny perhaps maybe 40 meters or so in the other dimensions that's a very unusual shape we don't see that in our solar system none of the asteroids in our solar system looked like that so it's very puzzling how it could have obtained this shape we also see that it's a very reddish in color which indicates that it's been possibly in space a long time and they radiated by not only the light from our Sun but other Suns as well there's still quite a bit to learn about this interstellar object and and limited time because it's on its way out of the solar system it's fading very fast it's a relatively small object so it's very dim but we are continuing to try to use NASA assets like the Hubble Space Telescope and Spitzer to take observations to determine more about its size and Composition you NASA's planetary defense coordination office has a near Earth object observations program which funds efforts that survey the skies to look for near-earth asteroids and to calculate their orbits and their trajectories and to determine if any of them might pose a hazard to earth and as part of doing that some amazing discoveries can happen and the discovery of this interstellar object was one of them as our observational capabilities improve pan-starrs has been getting better other surveys have been getting better there are a new generation surveys that will come online we will be detecting more of these in the future you
