Editor’s note: when our first missions – human or robotic – arrive at a new world we’ll want to do glean as much information from space – via fly by […]
The nature of the sub-Neptune K2-18b is debated between Hycean and mini-Neptune interpretations.
A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study argues that the […]
Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet’s surface.
Between 2.4 and 0.6 Gy ago, our planet underwent several episodes of global glaciations, including the Snowball Earth case that ended 635 My ago.
The tropical oceans that once served as oxygen-rich havens for Earth’s earliest complex life have become the planet’s largest marine dead zones. The dramatic reversal occurred hundreds of millions of […]
Using images from cameras on Mars orbiters, an international research team led by the University of Bern has discovered structures on Mars that are very similar to classic river deltas […]
The Cassini spacecraft orbited Saturn from 2004 to 2017, performing over a hundred flybys of Titan, Saturn’s largest moon.
Water and land surfaces on a planet interact with gases in the atmosphere and with radiation from the star. These interactions define the environments that prevail on the planet, some […]
In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations.
