Astronomers have found newborn stars in gas pouring out of a galactic nucleus.
A recently discovered supernova in Lupus now shines around magnitude +11.5, bright enough to see in a modest telescope. With photos and maps, we'll get you there. I wished I lived in Georgia and not just for the peach trees and warmer weather. No, I'd be able to get up early tomorrow morning to marvel at…
Astronomers have discovered long filaments of cold gas — the ingredient for making stars — cocooning giant bubbles inflated by a black hole.
Hubble has spotted more than 100 small, faint galaxies in the young universe, common as dust bunnies but previously out of reach of even the best telescopes.
Astronomers have discovered a giant cosmic void that explains why our Local Group of galaxies is moving through the universe as fast as it is.
Astronomers have discovered an object in the active galaxy Cygnus A that wasn’t there before.
The Chandra X-ray Observatory has gazed at a small patch of sky for almost 12 weeks, revealing 1,008 X-ray-emitting sources — most of them supermassive black holes.
For the first time, a team of astronomers has placed a fast radio burst on the cosmic map, allowing them to better pinpoint its mysterious origin.
From the discovery of gravitational waves to the building evidence that a massive planet could exist beyond Pluto, it has been a thrilling year for astronomy research. We recap.
A Hubble image of a nearby, massive elliptical galaxy reveals tenuous filaments that appear to be connected to the growth of the galaxy's supermassive black hole.
Astronomers have mapped neutral atomic hydrogen, which profuses the space between stars, in unprecedented detail to create a beautiful radio-wavelength portrait of the Milky Way.
The news that astronomers find the universe has 10 times more galaxies than previously thought? There's less to this than the headlines say.
ALMA, the largest telescope array in the world, took a look at the Hubble Ultra Deep Field, and revealed the cosmic history of star formation.
Astronomers have found a unique trait of spiral arms that supports a longstanding idea about where these patterns come from.
Living in voids might be tangentially responsible for three small galaxies’ recent flurries of starbirth.
Undergraduate students in Japan stumbled upon a rare lensing of two distinct background galaxies.
Astronomers take a second look at UGC 1382 — previously considered a typical elliptical galaxy — and reassess everything they know about its size, age, and formation.
In its first — and final — month of flight, the Hitomi X-ray observatory measured the calm within the bubbling core of the Perseus Cluster.
Astronomers may have solved the case of the Milky Way’s missing satellite galaxies. The solution? The galaxies never existed.
Astronomers have detected three cold gas clumps falling toward a galaxy's center — at odds with the prevailing idea for how black holes grow.
Astronomers discover a vast collection of young galaxies from the early universe.
A galaxy in the midst of a merger isn’t forming stars, even though it could. Astronomers think the galaxy’s central black hole might be the reason why.
Astronomers using the ALMA array of radio dishes have detected a dwarf galaxy 4 billion light-years away by the pull of its dark matter.
Astronomers studying the infrared glow that pervades the universe have pinned down its source: dusty, faint, and faraway galaxies.
Astronomers have identified 53 “super spirals” — spiral galaxies that are huge and incredibly luminous — as part of a project exploring archived observations.
