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.
Life and Death in Nearby Galaxies
New images of nearby galaxies and their surroundings reveal details in galactic formation and evolution — and puzzles that remain to be solved.
A Cosmic Collision Could Have Made Two Dark Matter–Less Galaxies
Astronomers connect the dots between two strange doppelganger galaxies, uncovering what might be a string of galactic pearls created in a cosmic collision 8 billion years ago.
Happy Birthday, Hubble!
The Hubble Space Telescope turns 32 on April 24th, and the team behind the telescope is marking the occasion with the release of a galactic family picture.
Hubble Image Reveals Possible Quasar Forerunner
A distant object in a deep Hubble Space Telescope field could be in transition from ordinary galaxy to brilliant beacon of light.
Are These the Most Distant Galaxies Yet Seen?
Two fuzzy red objects in the early universe may be galaxies shining at us from only a few hundred million years after the Big Bang.
Meet Earendel, the Most Distant Star Astronomers Have Observed
The Hubble Space Telescope has revealed a single star whose light has traveled for 12.9 billion years to Earth — the most distant star known.
New Image Reveals Possible Origins of “Odd Radio Circles”
This faint ring of radio emission might signal a momentous event in galactic evolution. Then again, it might be something else entirely.
Magnetic "Spoon" Feeds Supermassive Black Hole
Astronomers have imaged the magnetic field along which gas flows to a galaxy's central black hole.
Supermassive Black Hole Hides Behind a Ring of Dust
A high-resolution infrared image has revealed a dust screen obscuring a gas-devouring supermassive black hole in the center of the galaxy NGC 1068, confirming 30-year-old predictions.
How Galaxies Lose Their Dark Matter
A careful study of cosmological simulations shows that dark matter–less galaxies aren't impossible — just really rare.
Dwarf Galaxies Shed Light on Black Hole Origins
Astronomers are searching nearby dwarf galaxies for the ancient origins of supermassive black holes.
Astronomers Find Confounding Cone Shape in Cluster Collision
Galaxy clusters take eons to collide. Now, astronomers have caught a pair of merging clusters in an in-between stage never seen before.
How Our Largest Dwarf Galaxy Keeps the Others In Line
New research may explain why satellite galaxies align themselves around the Milky Way
Nearest Supermassive Black Hole Pair Discovered
Astronomers have observed a pair of supermassive black holes set to collide in 250 million years.
60-second Astro News: Magnified Galaxies Provide Window to Early Universe
Astronomers use cosmic magnifying lenses to peer into the universe's distant past.
Watch Black Holes Grow, Galaxies Fall
Watch black holes grow and galaxies fall — astro photos and visualizations to get you through the week.
Lost & Found: Milky Way-size "Orphan Cloud"
Astronomers have found a giant gas cloud, likely stripped from its parent galaxy long ago, in a cluster 330 million light-years away.
Galaxies That Evolve Together But Don’t Stay Together
A study of 36 dwarf galaxies within a volume of space spanning 13 million light-years show they all have remarkably similar histories despite the vast distances between them.
