The first mission designed to hunt a meteorite that crashed into the ocean has now discovered what may be tiny fragments of the meteorite's crust, researchers say.
Nearly every meteorite that falls onto Earth may ultimately come from a half dozen or so lost worlds that splintered apart soon after the birth of the solar system, a new study finds.
For the first time, astronomers have discovered a galaxy cluster that was hiding in plain sight, not far from the Milky Way.
Complex organic molecules have been discovered for the first time coming from the depths of Saturn's moon Enceladus, a new study reported.
Electric thrusters for spacecraft are increasingly shrinking, and could prove key for new interplanetary missions, experts say.
A new startup called Aevum aims to launch satellites to Earth orbit every 3 hours using rockets carried on a fully autonomous unmanned airplane.
A dust-enshrouded giant black hole ripping apart a star blasted out a superfast jet of particles that packed about 125 billion times the amount of energy the sun releases per year, a new study finds.
A black hole could have 1 million planets orbiting near it that are potentially capable of supporting life as we know it, an astrophysicist suggests.
Lightning storms on Jupiter are much more frequent, and much less alien, than previously thought, a pair of new studies suggests.
Physicists speculate that decaying neutrons may be producing particles unknown to science that make up the elusive dark matter.

This is a serious question, and serious scientists are speculating about what traces these potential predecessors might have left behind.
Worlds with twin suns, like Luke Skywalker's fictional home Tatooine in "Star Wars," may be rare because closely paired stars gravitationally hurl planets away from them, a new study finds.
Any alien civilizations born on "super-Earth" planets may be ground-bound by their home worlds' powerful gravity, a new study suggests.
