Earlier this week, astronomers from University of California in Santa Cruz announced the discovery of an Earth-sized world in a very promising spot around the red-dwarf star known as Gliese 581. It seems to be orbiting in that star's habitable zone.

Watch this vid for the complete announcement:

  • @mrdontgiveafuuck Actually no. The habitable zone is the distance from a star in which a planet can maintain liquid water on its surface. Just because a planet is in that zone doesn't neccessarily mean there is water on it.. In fact, the odds are highly against it.. which is what I was trying to point out.

  • @546046 A habitable zone is where water exists in a liquid state. Aint I right?!??

  • even if we found a planet we cannot reach it!

  • @bshieldsbb01 yes it is. also consider gas giant planets in stars' habitable zones, they could have earth-like satellites.

  • @jaymarlex200 NO it like earth has tree,grass,water liquid ,oxgyen,and more as gliese 581g is has habitable zone. We not yet proof of them !!

  • @tcsdef That's a red giant buddy.

  • you could also make a video using the least suggested idea :-)

  • @tcsdef REd dwarfs are like the usn,just smaller and less bright. It's the RED GIANTS that is the bad news

  • if the planet belongs to a star that is a RED dwarf, wouldnt that mean the star's and that whole solar system's life is coming to an end?

    wouldnt that also mean that life on that earthlike planet has ended?

    in 200 years, as it says in the link provided, when we have more info, that planet would become like venus or mars today

  • you should watch you back, you're under survelance by your government. look at the car at your back and find out who are they. Hmmmm maybe, just maybe :)
