NASA's Lucy spacecraft, currently journeying toward Jupiter's orbit on its asteroid-hopping mission, captured an impressive close-up of its second target: the main belt asteroid 52246 Donaldjohanson.
Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.
The Andromeda galaxy's family of satellite galaxies point towards the Milky Way, and nobody knows why.
A fleet of cubesats will act as a radio telescope to map the cosmic Dark Ages, its builders say.
Astronomers have observed a twinkling star and discovered an abundance of mysterious plasma structures in our cosmic neighborhood.
While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared.
The infant universe's population of huge black holes could owe itself to ultralight dark matter, scientists say.
New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.
On Easter Sunday (April 20), NASA's Lucy probe will zip past the asteroid Donaldjohanson, testing its science instruments on the space rock.
Using NASA's Perseverance rover to analyze Martian rocks, researchers suggest that Mars' complex volcanism might hold clues about the planet's ancient habitability.
