Combining with one other previously confirmed planet, one of our closest stellar neighbors now has a family of four.

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 ...

New research from UCLA and Princeton shows that under extreme heat and pressure, these elements mix and even “rain out” within young planets. When planets are newly formed, they can be extremely hot, ...

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 ...

Under the intense heat and pressure of newborn planets, water and gas react with each other, creating unexpected mixtures in the atmospheres of young Earth-to-Neptune-sized planets and a "rainfall ...
