Webb Telescope Unveils 19 Galaxies in a New Light
A James Webb Space Telescope survey known as PHANGS has revealed exquisite, just-published details in 19 nearby galaxies.
The Milky Way Might Have Started Out Shaped Like a Pickle
Faraway dwarf galaxies in the universe's distant past — which will become modern Milky Ways — have an unexpectedly stretched-out appearance.
Astronomers Discover “Invisible” Galaxy
A radio survey has serendipitously uncovered a galaxy with no visible stars.
Odd Radio Circles: The Remnants of Furious Galactic Winds
New evidence suggests extreme starbursts and furious galactic winds are at the heart of odd radio circles (ORCs).
JWST Reveals Distant “Galaxy” Is Six-way Galactic Crash
Peering deep into the past, the James Webb Space Telescope’s keen detectors are revealing unprecedented details of some of the oldest structures in the universe.
Astronomers Find 100,000-light-year Bow Shock in the Milky Way’s Outskirts
New simulations showed astronomers where to look for evidence of a dwarf galaxy's bow shock as it crashes through the Milky Way's halo.
Dark Halos and Warped Disks
Galaxies are embedded within halos of dark matter, and the tilt of those halos can affect the galaxy's stellar halo and stellar disk.
Webb, Hubble Telescopes Team Up to Create "Most Colorful View of the Universe"
The Hubble and Webb Space Telescopes have revealed a bounty of galaxies in a pair of colliding clusters, capturing twinkling lights within.
New Cosmology Probe Presents First, Stunning Images
The Horsehead Nebula and other stunning scenes highlight the talents of the just-launched Euclid mission. The telescope will reach into the depths of the cosmos to understand dark matter and dark energy.
Ghost-like Galaxy Defies Dark Matter Model
Astronomers have discovered a large but very dim ghost-like galaxy. Its existence challenges our notions of dark matter.
Kite-like Galaxy Trails a Million-light-year String of Gas and Star-forming Knots
A galaxy 600 million light-years away appears to be trailing gas in a string 1.2 million light-years long, but explaining its origins presents a challenge.

See Summer's Best “Gobbled” Globulars
Mergers between the Milky Way and long-ago dwarf galaxies have enriched our skies with dozens of iconic globular clusters. Many are visible in small telescopes.
Webb Telescope Tracks Universe's First Light
New results from the James Webb Space Telescope find that radiation from ordinary galaxies cleared the primordial haze left over from the Big Bang, allowing the first light to shine through the early universe.
Even Lonely Black Holes Need to Eat
Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.
Signal Found from Supermassive Duo's Second Black Hole
Astronomers have long suspected that a distant quasar harbors not one but two supermassive black holes. They've now detected OJ 287's second black hole.
James Webb Space Telescope Uncovers Hundreds of Galaxies in Early Universe
In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.
Red Galaxies at Night, Astronomers' Delight: A Look at the “Hubble-Dark” Universe
JWST images of early galaxies have turned up a population of flat, red disks that may have been entirely missed by previous surveys.
“Rogue Black Hole” Could Be Something Much Simpler
An unusual streak of stars thought to have formed in the wake of a wandering supermassive black hole might just be a spiral galaxy seen edge-on.
The James Webb Space Telescope May Have Spotted a Baby Galaxy Merger
New JWST images reveal that one of the most distant objects ever observed is actually two baby galaxies on a possible collision course.
