NASA announces exciting new star system
I'm excited to announce today that Dr Michael Gillon and his team have used our Spitzer Space Telescope to determine there are actually seven earth-sized planets orbiting the nearby TRAPPIST-1 star about 40 light years away.
What's more, as you can see in this illustration is that three of these planets marked in green are in the habitable zone, where liquid water can pull on the surface, in fact with the right atmosphere conditions, that could be water on any of these planets.
So, for the first time we found as many terrestrial planets around a single star.
And that's the first time we have been able to measure, in addition to that, both the masses and the radii of these habitable [UNKNOWN] type Earth-sized planets.
These planets are among the best of all the planets we know to follow up to see, for example, with the James Webb Space Telescope that we're gonna launch last year.
That atmospheres and also the local buyer signatures if there are any.
The discovery gives us a hint that finding a second earth is not just a matter of if, but when.
