New Earth-like planet found
#1
A distant Earth-like exoplanet 'could have life'

Quote:Astronomers have detected an Earth-like exoplanet that may have just the right kind of conditions to support life.

Gliese 581g lies some 20 light-years away in its star's "Goldilocks zone" - a region surface temperatures would allow the presence of liquid water.

Scientists say that the newly found world could also potentially have an atmosphere.

Exciting news. Yes

Big news if it's accurate. But wasn't Gliese 581 c, and d both thought to be in the habitable zone? This is a confusing star system. Wacko

I'm no scientist or atmospheric physicist, but if one side of the planet hot and perpetually facing the star, and other side is perpetually dark and cold, wouldn't that lead to hurricane force winds and weather?

Actually things would be very stable, depending on axial tilt, which is the main determinant of weather. The differences between the hot and cold sides would have long settled into an equilibrium, with energy flow minimal.

This is why we need to continue exploring space. I hope some form of life truly exists there. The only thing I hate is that we're not capable of being there right now. Sad

If there is life there, I bet in 20 years the headlines there will read "Dirty monkeys of the Sol system are spying on us. Public call for death ray activation". Laugh

i take it there isn't a way to get there with our current technology?

I think we could, with some kind of ion or nuclear propulsion. Don't forget Velocity = Acceleration x Time. You could attain near-light speed velocity if you could keep accelerating long enough and had enough fuel.
