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.
