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

If volcanoes on the planet released a bit more hydrogen than the team’s models call for, it could hold onto liquid water, he added. That could mean good news in the hunt for life.

To be clear, the volcanoes on the planet have not been confirmed, but there is some pretty good reason to believe they exist. LP 791-18 d actually has two sibling planets that also orbit the same ...

Volcanoes, however, aren’t always a bad things for planets: Eruptions on the surface of LP 791-18d could seed its atmosphere with gases and even water. “I have no idea what it would feel like to stand ...

If the planet absorbs as much light as Earth does, the researchers estimate that its average temperature would be over 120° C. Even if it reflects as much light as Venus, it would still average ...

Mars famously has the largest volcanoes known to science. The largest is Olympus Mons, which towers 22km (13 miles) above the surrounding plains—over two and a half times taller than Mount Everest.

Volcanoes that belch hydrogen could bump up the number of potentially habitable planets in the universe. Ramses Ramirez and Lisa Kaltenegger, both of Cornell University, modeled the atmospheres of ...

New observations reveal that Mars could still be volcanically active, raising the possibility for habitable conditions in the near surface of Mars in recent history. Ongoing research investigates ...

Volcanoes spewing hydrogen could help make an otherwise inhospitable planet habitable, keeping it warm enough for liquid water to remain on the surface, as in this artist’s image.(Image credit ...
