Life needs an atmosphere, but how much is too much?
How much atmosphere is too much for life? As scientists discover more super-Earths and mini-Neptunes, the question becomes more relevant.

(Phys.org)—A new model developed by a team of researchers with member affiliations in Argentina, France and Mexico, depicts a possible scenario to explain why gas giants do not migrate into the star they are orbiting during ...
Luke Skywalker's home in "Star Wars" is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, and many researchers ...

Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths—planets larger than Earth but smaller than Neptune. If so, those planets are long gone—broken ...

Like many a scientist before me, I have spent this week trying to grow a crystal. I wasn't fussy, it didn't have to be a single crystal – a smush of something would have done – just as long as it had a bit of long-range ...

How did the Solar System's planets come to be? The leading theory is something known as the "protoplanet hypothesis", which essentially says that very small objects stuck to each other and grew bigger and bigger—big enough ...

A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere. The probes would last an estimated 15 minutes ...
