Berkeley — Discovery of the last piece of a long-standing puzzle — what happens to hydrogen gas in the atmosphere — will help scientists assess the impact of additional hydrogen escaping into the ...

Earth's water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth's formative years, according to new work from ...

We may find alien life on a planet unlike any place in our Solar System — and we may find it soon. A huge planet called K2-18b has methane and carbon dioxide mixed in with its mostly hydrogen ...

Planets can be extremely hot when they are born, and new computational experiments show that such planets would have an atmosphere composed of a homogenous mixture of hydrogen and water. As the ...

A new University of Colorado at Boulder study indicates Earth in its infancy probably had substantial quantities of hydrogen in its atmosphere, a surprising finding that may alter the way many ...

Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at ...

Artist's impression of a hycean planet. A hycean planet is a hypothetical type of planet, described as a hot, water-covered planet with a hydrogen atmosphere. The presence of extraterrestrial liquid ...

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, researchers think they have a good explanation for a warmer, ...
