Earth-Like Planet Found


Astronomers based out of Hatfield, England, have discovered two planets that have conditions close to that of our own life-supporting Earth. One planet, Gliese 581 e, is of the right size, meanwhile Gliese 581 d is in a "habitable" zone.

Gliese 581 e is only 1.9 times the size of Earth, while other planets discovered outside our solar system were all that of Jupiter's size. Gliese 581 d has an orbit around a sun-like star that could allow liquid to form on the planet.

Finding rocky Earth-like planets is proof that scientists are getting better, and closer, to finding life-bearing bodies. Of the nearly 350 exoplanets (planets outside our solar system) found to date, nearly all have been found to be uninhabitable.

  Scientists getting better?  
Surely it just means they were looking at the right area of space at the right time :D

  Much more at source  
They talk about possible ocean sized bodies of water. Pretty cool stuff. My thing is this, scientist search for planets that sustain "life". But it is life as we know it. Life may take on a whole new meaning elsewhere in the universe.

  this is so cool  
my favorite kind of news

  who wants to move?  
If its like earth, has the same habitat and weather... who wants to move. Seems like a lot of work for the same old thing (and a hell of a lot of work to get it up and running)

What a good find and great summary!
Thank you.

  nice post, homegrown  
i take issue with your name, but you pulled up a good article and put in a good summary.

a refreshing break from all the rest of the news that says "OMG!! IT'S DANGEROUS OUT THERE! THE WORLD IS ENDING! LEFTIES/RIGHTIES/FUNDIES ARE GOING TO DESTROY US ALL!!"

  20 1/2 light years away..  
Lets hope its still there when we go out looking for it.

  Wait a minute...  
Gliese 581 d is 8 times larger than Earth. It may have liquid oceans, so it could be capable of supporting life and it orbits a red star. This may or may not be the source of our salvation. Of course, I'm talking about the planet Krypton.

  @skittles, capt.chainsaw  
skittles: Correct me if I'm wrong, but if it's 20 light years away, aren't we observing this planet as it was just 20 years ago? Chances are good that it's still there. But ...

@chainsaw: Correct me if I'm wrong, but wouldn't a planet 8 times the mass of Earth have 8 times the gravity? We might not enjoy that very much ...

And I forgot one; @sprog: Yes, scientists are getting better. Over the past few decades, the methods they've developed for observing extrasolar planets have become much more sophisticated.
  by: Ben_Reilly     04/22/2009 07:52 PM     
I'm not sure what the gravity exponent on that is, but yes, it's likely to have a much higher gravity level. However, this is why the Kryptonians can fly while they're on earth. On Krypton, they're used to this high gravity, but the come here and up, up and away!
  by: captainchainsaw   04/22/2009 08:30 PM     
Thanks for the props. I've been trying to put in an effort here at SN. I'll be building a rocket ship to move, it's gonna have 4 seats...any takers?
  by: homegrown420     04/22/2009 08:46 PM     
  simple solution  
we could just put Mike Moore into the orbit of Gliese maybe this would counter the planets gravity and keep intruding alien civilizations at bay.

If you'll take enough of your plants and seeds with you, I'd say "Engage"!
  by: Fonzo   04/22/2009 10:04 PM     
  So i'd weigh over 650 kilos on the surface??  
... enough to tear your internal organs from your moorings and have them collect in a pile in your lower gut. Assuming you could even stand. And your legs would balloon out to trash bag proportions.

Definately suited more to kryptonians than us.

  Well I was going to move but....  
If I'm going to weigh that much forget it. I'm having enough problems trying to lose weight, all I need is to put on another 1000 lbs. And my boobs already sag enough. I don't need to be tripping over them. Just one question. Do they have good weed there?
  by: Valkyrie123     04/23/2009 04:48 AM     
Good stuff! Hopefully we can colonize these planets in the future or similar ones...

  issue with his name?  
i don't get it. do you hate marijuana or something?
