Galaxies

The galaxy MoM-z14 could offer clues to what the universe looked like in its early infancy

Astronomers puzzled out minuscule distortions in images of faraway galaxies taken by JWST in order to chart the invisible

Puzzling red spots in images from the James Webb Space Telescope are probably young supermassive black holes obscured by dense cocoons of gas

A wobbling jet from a giant, voracious black hole is suppressing star formation in a distant galaxy—and astronomers have never seen anything quite like it before

Scientists have found the best evidence yet for long-predicted “failed galaxies”

Record-breaking objects can tell us about the most powerful events in the cosmos—sometimes

In our topsy-turvy universe, sometimes the farther away an object is, the bigger it seems to be

Centuries before other galaxies were known to exist, astronomers called them “spiral nebulas.” Today the defunct term still sparks confusion

Observations show the disk of our galaxy is not flat but warped and waving. Astronomers are still working out the reasons why

A cosmic explosion known as GRB 250702B is by far the longest gamma-ray burst astronomers have ever seen—if it’s even one at all

Huge eruptions from the Milky Way’s supermassive black hole in the distant past may have sterilized much of the inner galaxy

Voracious supermassive black holes light up the cores of “active” galaxies across the universe. How we see them, however, is a matter of perspective
