Having already discerned the dwarf planet has distinct surface features, NASA's New Horizons mission has now spotted not just Pluto's largest moons, but the smallest natural satellites too.
New research suggests that the frozen cores of 'mini-Neptunes' could be transformed into habitable worlds with a little help from their red dwarf hosts.
Heavy metal ferroelectric "snow" may cover Venus' highest mountain peaks, boosting the alien nature of Earth's weird 'twin.' Continue reading →
It's as if Titan is getting festive for Hallowe'en -- astronomers have detected a ghostly glow around the the north and south poles of the Saturnian moon that had previously gone undetected. Continue reading →
The first-ever photos of water ice near Mercury's north pole have come down to Earth, and they have quite a story to tell.
A double star system with misaligned protoplanetary disks around 450 light-years from Earth has been discovered, potentially explaining why some exoplanet orbits can be wildly eccentric. Continue reading →
Heat radiating from the young Earth could help solve the more than 50-year-old mystery of why the far side of the moon, which faces away from Earth, lacks the dark, vast expanses of volcanic rock that define the face of the Man in the Moon as seen from Earth, researchers say.
