A team of astronomers claims to have sniffed out a “biosignature” in the atmosphere of a distant planet called K2-18b. But ...

Astronomers using ESO’s Very Large Telescope have discovered a truly bizarre planet — one that orbits two stars at a perfect ...

The James Webb Space Telescope may have detected life-associated gas in the atmosphere of a far-off planet. The news is being ...

Many other missions, both past and present, have revealed amazing insights about the planet's history, and future planned missions should help continue this progress. NASA aims to send humans to ...

"We found that planets change over time in two big ways: they shrink as they lose their atmospheres, and they move inward due to interactions with their star." "But 12 days is a tiny slice of ...

The most likely explanation is that these planets formed through a process called core accretion — where rocky and icy cores grew large enough to capture thick atmospheres of hydrogen and other ...

stellar radiation blows their atmosphere away, removing much of the gas and leaving a smaller world at the end of the process. The other possibility is that it is leftover heat from a planet's ...

These distant planets hold mysteries and peculiarities ... revealing the strange complexities of fluid dynamics in Saturn’s atmosphere. Titan, Saturn’s largest moon, offers a landscape unlike any ...

This artist’s impression shows the planet ... their atmospheres. Most models of how planets form assume that materials like gas, ice, rock, and metal don’t react much with each other.

UCLA and Princeton planetary scientists asked that question and got a surprising answer: Under the intense heat and pressure of newborn planets, water and gas react with each other, creating ...

The star’s flares are much more violent than previously thought, the researchers say, potentially obliterating the planet’s air. Not having an atmosphere, which traps important gases like ...
