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.
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.
“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.
New Observations Reveal Galaxies Near and Far
Astronomers at this month's big winter conference explored intriguing small galaxies at various points in cosmic history.
Webb's Galactic Distance Record Is Now Official
Spectroscopic measurements confirm Webb's distance record, with images revealing galaxies that existed just 330 million years after the Big Bang.
Webb Telescope Shatters Distance Records, Challenges Astronomers
Distant galaxies in Webb images suggest we need to rethink star and galaxy evolution in the early universe.
What We See in the First Science Images from the James Webb Space Telescope
The James Webb Space Telescope released its first science images today. Here's what these images show us.
What the James Webb Space Telescope's First Year Will Reveal
The James Webb Space Telescope's first year of observations promises to reveal exoplanet atmospheres and surfaces, infant galaxies, and maybe even the first black holes.
Watch Black Holes Grow, Galaxies Fall
Watch black holes grow and galaxies fall — astro photos and visualizations to get you through the week.
Not All Star-forming Clouds Are The Same
Astronomers have created the first high-resolution maps of the big, dense gas clouds that form stars within galaxies.
"Dead Ringer" for the Milky Way Found in Early Universe
A cosmic magnifying glass has revealed a Milky Way-like galaxy in the early universe that doesn’t conform to cosmologists’ expectations.
The Knife Edge Galaxy Throws Astronomers For a Loop
A 2008 image captured a stunning double loop of stars around an edge-on galaxy. Now, astronomers are questioning whether one of those loops exist.

Cold weather keeping you inside at night? Limit your time outdoors and make the most of your telescope time with these easy-to-find deep-sky gems.
What Snuffed Out Star Formation in This “Monster” Galaxy?
Astronomers have discovered a galaxy that formed five times as many stars as the Milky Way within 2 billion years after the Big Bang — but then quickly quelled any further starbirth.
How Young Galaxies Grow
A pair of recent studies sheds light on some of the universe’s earliest galaxies and how they grow.
Deep-sky Dive Into the Great Square of Pegasus
We return to Pegasus, but this time with a telescope to find a grab-bag of overlooked deep-sky treasures.
"Invisible" Galaxies Found in the Young Universe
Astronomers have discovered galaxies that have escaped detection until now, uncovering a missing link in galaxy evolution.
Why Are Two Ghost Galaxies Missing Dark Matter?
Ultra-diffuse galaxies are usually dark matter-rich. But astronomers have discovered two of these galaxies that lack dark matter altogether.
Tracing the Cigar Galaxy's Superwind
NASA’s SOFIA airborne observatory has returned a striking far-infrared view of the Cigar Galaxy and its “galactic superwind.”
