Euclid space telescope finds 1.5 trillion orphan stars wandering the Perseus cluster (images)
The Euclid telescope has allowed astronomers to discover a staggering 1.5 trillion orphan stars torn from their own galaxies to wander the Perseus cluster alone.
Scientists pick their favorite Euclid 'dark universe' telescope images: 'The best is still to come'
The European Space Agency has now released ten images from its dark universe detective spacecraft, Euclid. We asked scientists from various fields to pick their favorite Euclid image thus far.
Massive new NASA exoplanet catalog unveils 126 extreme and exotic worlds
A new catalog of the masses and widths of 126 new exoplanets showcases the extreme and exotic nature of worlds beyond the solar system.
NASA space telescope finds Earth-size exoplanet that's 'not a bad place' to hunt for life
NASA exoplanet-hunter TESS has found a temperate, Earth-size world in the habitable zone of its red dwarf star. This planet could make waves in the search for life.
'Death Star' black holes caught blasting powerful beams at multiple targets: Watch out Alderaan! (video)
Supermassive black holes that are blasting out beams of high-energy particles killing star formation in their galaxies are shifting targets like real-life Death Stars.
The Euclid 'dark universe detective' telescope has revealed new images of the cosmos — and they are remarkable
A new set of images has been released from Europe's "dark universe detective" Euclid, and they show that the space telescope is set to change the game for astronomy.
Euclid 'dark universe' telescope team will unveil new full-color images today (May 23): How to watch live
With the Euclid space telescope set to deliver a new batch of images on Thursday (May 23), we're looking back at the dark universe detective's achievements thus far.
Scientists find weird link between a solar mystery and feeding black holes
The solar dynamo that drives sunspots and solar flares could be located near the surface of the sun scientists find, solving a 400-year-old solar mystery and providing a weird link to black holes.
Churning spacetime and destroyed stars help reveal how fast supermassive black holes spin
Black holes are such a drag! Especially for the guts of stars they've destroyed and the fabric of spacetime they pull along with them.
Amateur astronomer finds 5 fascinating new galaxies — and they're now named after him
Giuseppe Donatiello is an amateur astronomer with a unique distinction: discoverer of 11 galaxies, nine with his name.
Stars give tiny planets a gravitational 'squeeze' to strip away their atmospheres
Modeling distant planets has revealed that tidal forces generated by their parent stars can combine with intense radiation bombardment and strip away their atmospheres.
Young 'cotton candy' exoplanet the size of Jupiter may be shrinking into a super-Earth
Astronomers have found that one of the lightest exoplanets ever seen, the young 'cotton candy' world V1298 Tau b, may be shrinking from the size of Jupiter to the width of a super-Earth.
Right again, Einstein! Scientists find where matter 'waterfalls' into black holes
Einstein was right! Scientists found the first-ever evidence of "plunging regions" of spacetime where matter inexorably falls into black holes, as predicted by general relativity.
Bright green fireball lights up the skies over Portugal and Spain (photos)
On the evening of Saturday (May 18) a bright fireball lit up the skies over Portugal and Spain in stunning green and blue as it streaked through Earth's atmosphere.
James Webb Space Telescope sees Orion Nebula in a stunning new light (images)
The Orion Nebula may be a familiar astronomical sight over Earth but that hasn't stopped the James Webb Space Telescope from seeing this star-forming region in a stunning new light.
Japanese-European spacecraft bound for Mercury weakened by thruster glitch
The thrusters of Mercury-bound spacecraft BepiColombo are operating at less than full capacity, and operators are racing to find a solution.
James Webb Space Telescope spots most distant and oldest black hole collision ever seen (video)
The James Webb Space Telescope has detected a merger between two supermassive black holes so distant it proceeded just 740 million years after the Big Bang.
In the Milky Way, 3 intruder stars are 'on the run' — in the wrong direction
Three ancient stars that hail from cannibalized dwarf galaxies are "on the run" at hundreds of thousands of miles per hour in the Milky Way's galactic halo.
Cotton candy exoplanet is 2nd lightest planet ever found
"The planet is basically super fluffy."
Milky Way's halo is filled with 'magnetic donuts' as wide as 100,000 light-years
The discovery could help astronomers better understand how cosmic magnetic fields form and evolve.
Earth-size planet discovered around cool red dwarf star shares its name with a biscuit
Astronomers have discovered an Earth-size planet orbiting a red dwarf star, making just the second planetary system seen around one of these tiny, cool, dim, but common, stars.
NASA's Chandra spacecraft spots supermassive black hole erupting in the Milky Way's heart
NASA's Chandra X-ray space telescope has spotted the supermassive black hole at the heart of our galaxy erupting, proving even quiet black holes like Sagittarius A* need to vent sometimes.
Cracking! Some binary black holes may roll around each other in egg-shaped orbits
Some black hole pairs roll around each other in wobbly, egg-shaped orbits that could hold clues about their origins, gravitational wave measurements suggest.
