Gas Seen Moving Near the Event Horizon
Astronomers have detected three flares from near our galaxy’s central black hole that look like gas closely orbiting the unseen object.
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.

Video: The Glow of Spiraling Black Holes
New calculations reveal what two supermassive black holes about to merge would look like in ultraviolet and X-rays.
Middleweight Black Holes Provide Window to Early Universe
How did supermassive black holes form? Two studies discovered dozens of middling-mass black holes in dwarf galaxies to fuel an ongoing debate.

Star Swings Around Black Hole, Tests Gravity
Astronomers have seen a star’s light redden as it passed our galaxy’s central black hole, just as general relativity predicts.
Scientists See Strong Evidence of Rare Middle-weight Black Hole
New observations give more fuel to the concept of intermediate-mass black holes.

Black Hole Destroys Star and Shoots Jet
Astronomers have watched the growth of a jet fueled by a shredded star.
More Mystery Objects in the Galactic Center
Astronomers have discovered three more red, dusty objects near the Milky Way’s central black hole that could be merged stars.
Do Big Black Holes Wander the Galaxy?
New simulation work suggests that galaxies like the Milky Way could be home to a dozen supermassive black holes.
Our Galaxy's Center Might Hold Thousands of Black Holes
A new study has uncovered a dozen stellar-mass black holes within 3 light-years of the supermassive black hole at our galaxy’s core — and these might be just the tip of the iceberg.
Physicist Proposes Alternative to Black Holes
A physicist has incorporated a quantum mechanical idea with general relativity to arrive at a new alternative to black hole singularities.
Neutron Star Powers Ultraluminous X-rays
It turns out that neutron stars — not black holes — power at least some ultraluminous X-ray sources.
Astronomers Watch Donut Rotate Around Supermassive Black Hole
Astronomers have detected a torus rotating around the supermassive black hole at the center of spiral galaxy Messier 77, collecting observations that may shed light on why these weird structures exist.
60-Second Astro News: Merging Black Holes, Distant Super-Supernova, and Arecibo's Fate
Supermassive black holes en route to merger have strange dynamics in their gas disks. Astronomers have spotted the most distant spectroscopically confirmed supernova. And NSF decides the fate of the Arecibo Observatory.
60-Second Astro News: Black Holes Galore
Supermassive black holes are difficult to observe and measure, yet they have profound effects on their host galaxies. Read up on the latest black hole discoveries presented at the Washington D.C. meeting of the American Astronomical Society.
Most Distant Black Hole Yet
Astronomers have discovered a supermassive black hole scarfing down gas just 690 million years after the Big Bang.
Infant Stars Huddle near Black Hole
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
