Rogue moons, torn from their planets and flung outward to drift through space, may be as common as stars in the universe, a new study finds.
R2-D2 and BB-8 are the droids that NASA is looking for — "astromechs" that can help repair spaceships on the fly, a NASA robotics engineer says.
Cyclones encircling Jupiter's poles mysteriously arrange themselves in clusters with pentagonal and other geometric shapes, a new study finds.
The colorful stripes of Jupiter run hundreds of miles deep and hold so much gas that their mass is about three times that of the entire Earth, three new studies find.
The origins of "pulsating auroras" — intense flickering displays of light high up in Earth's atmosphere — are now revealed after a decades-long hunt, a new study finds.
A new software program that uses artificial intelligence can help rapidly detect and analyze gravitational waves, or ripples in the cosmic fabric of space-time, a new study finds.
New research may have identified an early warning sign of how powerful explosions from the sun might get, shedding light on whether they could damage communication satellites and power grids.
New work probes the extraterrestrial source of incredibly powerful explosions of radio waves, investigating why that spot is the only known location to repeatedly burst with these blasts.
Technology in development could capture images from an Earth-size planet in the nearby Alpha Centauri system in the 2020s, new research suggests.
Heavyweight stars up to hundreds of times the mass of the sun may be more abundant than previously thought, a new study finds.
The presence of life might influence how fast a planet spins, releasing gases such as oxygen that can crank up how quickly a world turns, a new study finds.
Ice on Jupiter's moon Europa may drift across the satellite's surface from the equator to the poles, or vice versa, at a literally glacial pace, a new study finds.
For the first time, astronomers have detected evidence of a cocoon of material blasting out from a pair of merging neutron stars.
Although pulsars regularly blast out deadly gamma rays and X-rays, alien planets in orbit around them could theoretically be habitable by life, a new study finds.
Tahitian myth, South African nicknames, and ancient Chinese and Hindu titles are among the inspirations for the new names of 86 stars in the Earth's night sky, astronomers said.
The giant impact from an Earth-size rock that knocked Uranus sideways may have also helped create the tilted planet's moons, a new study finds.
A massive geomagnetic storm that was recorded across East Asia for nine days in 1770 suggests such solar flareups are surprisingly common.
Laboratory experiments on Earth can now simulate the conditions under which life might emerge on Saturn's moon Enceladus, as well as other icy alien worlds, according to recent research.
By analyzing cosmic rays in space, the "Monkey King" satellite from China is now helping pin down the identity of dark matter, a new study finds.
The mysteriously cold vortex of air whirling above the south pole of Saturn's moon Titan may result from its atmosphere's unique chemistry, a new study finds.
Learn how our solar system formed, how it was discovered and the names of the planets, dwarf planets and regions of space that orbit our sun.
Learn about the discovery of dwarf planet Pluto, its fascinating orbit and atmosphere and the controversy surrounding its planetary status.
The mystery of why the ocean beneath the icy shell of Saturn's moon Enceladus did not freeze over long ago may now be solved.
Lab experiments simulating the formation of new stars may have revealed why young stars give off much less X-ray radiation than expected, a new study finds.
