Astronomers puzzle over early origins of mysterious ‘red monster’ galaxy
Researchers are perplexed by a galaxy that seems too large and too dusty for its place in cosmic history, less than a half-billion years after the big bang
See the iconic Sombrero Galaxy in stunning new images that reveal its enormous glowing halo
This galaxy, also known as Messier 104, gets its nickname from its central bulge and outer dust trail, which give it a sombrerolike appearance from our vantage point
Something extremely weird is happening to our galactic neighbor. Scientists think they know why
The stars in the Small Magellanic Cloud aren’t behaving the way they should. A cataclysmic collision with another nearby galaxy may be the culprit
The sun and thousands of its twins migrated across the Milky Way just in time
The sun rode a massive galactic migration wave to the Milky Way’s suburbs
Could aliens in another galaxy see dinosaurs on Earth?
How big would a telescope need to be to see Earth’s dinosaurs from 66 million light-years away? Think big—and then think bigger
This vanished star may mark a ‘failed supernova’—and a newborn black hole
A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen
How can galaxies ever collide in an ever-expanding universe?
You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome even the stretching of space itself
Weird new object escalates ‘black hole star’ debate
Researchers have found what might be a little red dot transitioning into its final state, where x-rays burst through its gas cocoon. Others argue the object is nothing special
‘Baby cluster’ of galaxies may challenge cosmic models
Dating to only a billion years after the big bang, JADES-ID1 may be the earliest, most distant galaxy protocluster astronomers have ever seen
JWST spots most distant galaxy ever, pushing the limits of the observable universe
The galaxy MoM-z14 could offer clues to what the universe looked like in its early infancy
JWST unveils most intricate map yet of cosmic dark matter
Astronomers puzzled out minuscule distortions in images of faraway galaxies taken by JWST in order to chart the invisible
‘Little Red Dots’ Spied by JWST May Be Baby Black Holes in Disguise
Puzzling red spots in images from the James Webb Space Telescope are probably young supermassive black holes obscured by dense cocoons of gas
