"We're not saying, and we can't say, that there's no life in Europa. What we're saying is that it's a harder proposition, ...

After modeling Europa's conditions, the researchers concluded that its rocky seafloor is likely mechanically too strong to ...

In Earth's deep seas, tectonic activity creates hydrothermal vents, where hot water reacts with rock to supply chemical ...

New research raises doubts about Europa's potential for supporting life, due to the lack of tectonic and volcanic activity on ...

Computer simulations have revealed that a hostile, tidally locked exoplanet located roughly 45 light-years from Earth is capable of hosting tectonic activity on a massive scale. Tectonic activity is ...

Much of the brittle, upper crust of Venus is broken into fragments that jostle and move – and the slow churning of Venus’ mantle beneath the surface might be responsible. My colleagues and I arrived ...

Astronomers have been intently studying an exoplanet called LHS 3844b for many years. Back in 2019, researchers announced that they believed the planet was covered by dark lava rock. Researchers ...

This artist’s illustration represents the possible interior dynamics of the super-Earth exoplanet LHS 3844b. The planet’s interior properties and the strong stellar irradiation might lead to a ...

Rocks don’t appear to do much. But over millions of years, chemical reactions involving rocks can have a tremendous influence on Earth’s climate. Now researchers have amassed evidence that tectonic ...
