the most Earth-like planet yet outside our solar system, with balmy temperat
ures that could support water and, potentially, life.
They have not directly seen the planet, orbiting a red dwarf star called Gli
ese 581. But measurements of the star suggest that a planet not much larger
than the Earth is pulling on it, the researchers say in a letter to the edit
or of the journal Astronomy and Astrophysics.

see
whether some ETs would respond? hoho~

发帖数: 27 | 6 I guess they kind of overclaimed their finding. Since they haven't directly
seen the planet, the temperature they estimated for the planet is probably
based on the luminosity of the star and the planet's distance to the star.
Thus this 0-40 degree C is not necessarily the surface temperature of that
planet. If it had a thick "green house" atmoshpere earlier in its history,
then all the water (if there was any) would have been long gone ...just like
our Venus
