Planets on the inner edge of extrasolar habitable zones could be habitable for a couple of billion years longer than ...

Many rocky worlds orbiting other stars share characteristics with our sister planet, particularly those near their star’s inner habitable zone. If Venus’s history is typical of such planets ...

If Venus was, in fact, a steam world, it wouldn't be alone. Recent exoplanet discoveries like GJ 9827 d show evidence of worlds shrouded in hot steam. Astronomers often work off of two concepts for ...

A team of astronomers at the University of Cambridge, however, has just posited that Venus may be less a twin than that thought in that it may never have even had oceans. Their findings, published ...

"Even though it’s the closest planet to us, Venus is important for exoplanet science because it gives us a unique opportunity to explore a planet that evolved very differently to ours, right at the ...

But the likeness Venus shares with Earth, and its position at the edge of the Solar System's habitable zone, make it an intriguing research prospect. Was it ever habitable? Could it be habitable?

Venus provides a powerful limit on where this habitable zone lies around a star. "Even though it's the closest planet to us, Venus is important for exoplanet science, because it gives us a unique ...

Venus is important for exoplanet science, because it gives us a unique opportunity to explore a planet that evolved very differently to ours, right at the edge of the habitable zone," said ...

There’s also the optimistic habitable zone, which allows for the fact that Venus and Mars are both theorized to have once been habitable worlds; this suggests that Venus is on what’s called ...
