SUNSET: 
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.
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.
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.
"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.
Odd Jets Might Signal Dual Black Holes
Off-kilter, curved, and otherwise unusual beams of plasma from galaxies’ cores might track the dueling dances of two supermassive black holes.
Milky Way May Be Made with Swapped Gas
High-powered simulations suggest that half of the material in the Milky Way could come from other galaxies.
The Making of a “Frankenstein” Galaxy
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.
Super Spiral Galaxies
Astronomers have identified 53 “super spirals” — spiral galaxies that are huge and incredibly luminous — as part of a project exploring archived observations.
Seeing Shadows of Ancient Galaxies
A new technique lets astronomers measure nearly invisible clouds of hydrogen gas from across the universe.
Ancient Galaxies Seen Dying Inside-Out
Astronomers have found massive galaxies 3 billion years after the Big Bang that are dying from the inside out.
Question Reopened: How do Galaxies Grow?
Evidence from observations sheds doubt on cosmic cannibalism as a source for galaxy growth, suggesting that instead galaxies grow by pulling in gas from the intergalactic medium.
