The number 45 matters less than what it represents: the shift from open-ended discovery to structured search, and from chance ...

Only 11.4 light-years away, two exoplanets have been detected around a neighboring star. One of them, Gl725Bc, is located in the habitable zone and is now the second closest potentially habitable ...

Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known ...

Relative sizes of the newly discovered habitable-zone planets and Earth. Left to right: Kepler-69c, Kepler-62e, Kepler-62f and Earth (except for Earth, these are artists' renditions). Image credit: ...

Moons orbiting rogue planets, worlds flung from their parent star systems into the cold of interstellar space, could maintain ...

For a planet to have liquid water – something necessary to support life as we know it – it has to be within a certain distance of its star. Too close, and the water burns up. Too far away, and it’s a ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

The Earth and Venus, although not very different in size, have had a very different climate history. In the future, the Earth may look like Venus. Credit: Jeremy Leconte The bad news: Earth's oceans ...

Scientists have discovered natural space weather stations that exist around distant stars because these stations can ...
