"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 ...

Carbon dioxide in the atmosphere is a major driver of shifts in the Earth's climate, as we know all too well in our currently warming world. But it also works the other way – in the past too little ...

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 at ...

A new paper has revealed that tectonic activity on this planet—a unique feature in the solar system—could have been spurred by a stream of asteroid impacts. Previously, computer models have shown that ...

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 ...

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. On Earth, the heat generated from the radioactive decay of elements in Earth's mantle ...

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 ...
