Temperate sub-Neptunes Are Compelling Targets For Detecting Liquid-water Oceans Beyond The Solar System. If water-rich and lacking massive hydrogen-helium envelopes, these planets could sustain liquid layers beneath their atmospheres despite […]
Water vapour is highly subsaturated in much of the Earth’s atmosphere. This has important consequences for water vapour feedback, and also for general phenomena such as the runaway greenhouse.
A mystery interstellar object discovered last week is likely to be the oldest comet ever seen – possibly predating our solar system by more than three billion years, researchers say.
The origin of the terrestrial water remains debated, as standard Solar System formation models suggest that Earth formed from dry grains, inside the snowline of the Proto-Solar Nebula (PSN).
Recent claims of biosignature gases in sub-Neptune atmospheres have renewed interest in water-rich sub-Neptunes with surface oceans, often referred to as Hycean planets.
The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water.
This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid-latitudes of Mars.
Seventy percent of the Earth’s surface is covered with water, but water also flows beneath its surface.
As if someone has been sweeping the surface of Mars with a broom, the origin of odd, streaked slopes has intrigued scientists for decades.
Billions of years ago, water flowed on the surface of Mars. But scientists have an incomplete picture of how the Red Planet’s water cycle worked.
