Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...

Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for ...

Artist's depiction of a newly disovered rocky planet, called LP 791-18d, which may be covered in volcanoes. A second planet, LP 791-18c, orbits in the background. (Credit: NASA’s Goddard Space Flight ...

Volcanoes are a common feature on the surfaces of solid planets within the solar system, resulting from magmatic activity occurring within the planetary crust. On Earth, volcanism is driven ...

Until this week, Earth was the only planet known to have active volcanoes Astronomers knew that Venus had dormant volcanoes. Now, observations suggest they could be spewing lava right now ...

If all volcanoes erupted together, the planet would be plunged into darkness as ash clouds blocked the Sun and global cooling ...

The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.

Astronomers have discovered an exoplanet that is believed to be blanketed in volcanoes. Exoplanet LP 791-18 d is suspected to have volcano eruptions as frequent as Jupiter's moon lo, which is the ...

A dazzling image taken by NASA’s 2001 Mars Odyssey orbiter shows an unprecedented view of a 12-mile-high volcano poking through clouds at dawn on the Red Planet. Arsia Mons, which dwarfs Earth ...

Astronomers have discovered an Earth-sized planet they suspect is covered in volcanoes and could have the potential to sustain life. The planet, known as LP 791-18 d, is about 90 light-years away ...

An Earth-sized planet orbiting a star beyond our solar system is likely covered with volcanoes, researchers have concluded. The planet is technically an exoplanet, meaning it is beyond our solar ...
