Melting glaciers aren’t just a symptom of climate change — they could become a major cause of it. This video dives into new ...

The Fermi bubbles were discovered in 2010 by NASA’s Fermi Gamma-ray Space Telescope. The two orbs form an hourglass structure ...

The Solar System is a vast and mysterious realm, filled with planets, moons, asteroids, and icy bodies waiting to be ...

A volcanic eruption in southwestern Iceland has once again forced the evacuation of local residents and tourists at the ...

Over the past decade, researchers have been puzzling through Pluto’s mysteries. Meanwhile, the New Horizons probe heads for interstellar space.

Sedna, a distant dwarf planet three-quarters the size of Pluto, is inching toward the brightest star in our sky — and in 2076 ...

The biggest known ice volcanoes, which spew ice instead of lava, are located on Pluto. Now it turns out size is not the only feature setting apart Pluto's "cryovolcanoes" from all others. In a ...

Kiladze Caldera, formerly called Kiladze crater, may be a supervolcano that erupted fairly recently, spewing ice across the surface of Pluto.

Volcanoes—even ones that spew ice—need heat to erupt, so recent activity would suggest Pluto’s interior has more heat than previously thought, perhaps from radioactive elements in its core.

Strange features spotted on the surface of Pluto may be due to the activity of ice volcanoes, according to a new study using data from the New Horizons mission. The activity could have created ...

Researchers point to a region of Pluto largely made of bumpy water ice and filled with volcanic domes. One volcano is similar in volume to one of Earth’s biggest volcanoes: Mauna Loa in Hawaii.
