Astronomers discover 10 new moons for Jupiter

Most planets have moons, and Jupiter already had the most. Now, with these new ones, Jupiter has a whopping 79 moons altogether … so far.

Astronomers find ‘ghost dunes’ on Mars

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.

Innovative new instrument to seek habitable worlds

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.

These 2 exoplanets might have seasons and stable climates

New findings suggest that some exoplanets will have stable axial tilts and climates, much as Earth does. This knowledge will help astronomers search for worlds similar to ours – the long-sought Earth 2.0.

Stunning new views of Ceres’ mystery bright spots

Ceres’ intriguing bright spots have come into full view in these spectacular new high-resolution images from NASA’s Dawn spacecraft, now in its lowest orbit around the dwarf planet.

Enceladus’ water plumes contain life clues

Does the subsurface ocean of Saturn’s moon Enceladus contain any kind of life? Newfound complex organic molecules in its water vapor plumes hint we might not be alone in the solar system.

Astronomers see mystery explosion 200 million light-years away

Supernovae, or exploding stars, are relatively common. But now astronomers have observed a baffling new type of cosmic explosion, believed to be some 10 to 100 times brighter than an ordinary supernova.

Hayabusa 2 arrives at asteroid Ryugu

Japan’s Hayabusa 2 is now just 12 miles (20 km) from Ryugu’s surface. The spacecraft will now begin studying the asteroid to find the best locations for its lander and 3 small rovers.

Astronomers see a black hole eating a star

Astronomers now have the 1st direct image of a black hole ripping apart a star. The star-stuff goes into a disk surrounding the hole, and it’s also ejected back to space in powerful jets.

Life at Alpha Centauri? Maybe, NASA says

Could life exist on planets in the star system closest to ours, Alpha Centauri? Dangerous X-ray radiation makes it unlikely for the single exoplanet found so far. But new data suggest better odds for any new planets yet to be discovered.
