Io is small, but it's the most volcanically active world in our solar system. It has hundreds of active volcanoes. Now the Juno spacecraft has found one more.
Raging, planet-wide dust storms - like the one going on now - happen only every 6 to 8 years on Mars. Here's how NASA spacecraft are studying it, plus a cool before-and-after video!
When the Apollo astronauts returned from the moon, the dust that clung to their spacesuits made their throats sore and their eyes water. Lunar dust is made of sharp, abrasive particles, but how toxic is it for humans?
Spacecraft observations reveal plasma waves moving from Saturn to its rings and its moon Enceladus. Researchers converted a recording of the plasma waves into an audible cosmic whoosh that you’ll enjoy.
Robot orbiters circling Mars have acquired images of ghost dunes. They're pits where, scientists believe, tall crescent-shaped sand dunes once existed on this red desert world.
A new infrared instrument on a telescope in Hawaii will let astronomers find more exoplanets orbiting red dwarf stars. The discoveries may include rocky worlds that are potentially habitable.
Last week, scientists announced the 1st known source for ghostly, high-energy neutrinos. The source is a blazar, a billion-solar-mass black hole 3.7 billion light-years away. The discovery establishes a new way to study the universe.
