SUNSET: 
Does This Star Cluster Host a Black Hole in Its Core?
The well-known star cluster Messier 4 might have an elusive, midsize black hole hidden at its center, but the evidence isn’t conclusive yet.
“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.

First Image of Black Hole Shadow and Jet Together
For the first time, astronomers have seen how the big plasma jet shot out by a supermassive black hole connects to the material falling into the black hole.
The First Black Hole Image, Take Two
A new analysis of Event Horizon Telescope data sharpens our view of the glowing gas encircling the black hole.
Massive Black Hole Duo Spotted at Cosmic Noon
The most distant pair of supermassive black holes discovered offers a unique insight into how galaxies merge.
Watch the Milky Way’s Black Hole Spaghettify a Cloud
Two decades of observations show a dusty gas cloud elongating as it approaches our galaxy's supermassive black hole.
Have Scientists Found a Rogue Supermassive Black Hole?
An unusual stellar streak emerging from a distant galaxy might be a sign of a runaway supermassive black hole, scientists suggest.
Searching for the Seeds of Supermassive Black Holes
The seeds of supermassive black holes could show up in an upcoming sky survey with JWST.

The Challenge of Weird Black Hole Mergers
When spacetime shivers last only a fraction of a second — as in the case of the massive-black-hole merger GW190521 — astronomers struggle to uncover their origins.
X-rays Offer View Inside the Black Hole-Powered Plasma Guns
Polarized X-rays are helping astronomers take a closer look at blazars’ “plasma guns,” the particle jets powered by supermassive black holes.

Sneak Peek at Two Promising Comets
Ready to chase comets? We look at two fuzzy solar system travelers that will keep you on your toes all fall and winter long.
Shredded Star Reveals a Dwarf Galaxy’s Central Black Hole
A luminous flare provides astronomers with a rare opportunity to measure the mass of an otherwise quiescent black hole at the center of a dwarf galaxy.
Wobbly Star Reveals the Closest Black Hole Yet
The most compelling dormant stellar-mass black hole candidate in the Milky Way orbits a Sun-like star only 1,570 light-years away.

Hotspot Zooms Around Our Galaxy’s Black Hole
Astronomers have detected a bubble of hot gas circling our galaxy’s central black hole soon after seeing a flare, suggesting both arose from the same process.
Blazar's Outburst Hid Repeating Signal
Pulses originating almost a billion light-years away hint at extreme physics near a supermassive black hole.
Giant Black Holes Make Tiny, Ghost-like Particles
Blazars, the gas-guzzling black holes at the center of galaxies, could make most of the tiny particles known as neutrinos we catch on Earth.
A Black Hole Lurks in a Galaxy Near Our Own
Astronomers have found a dormant black hole orbiting a massive blue star in the Large Magellanic Cloud, a satellite galaxy of the Milky Way.
Where Did the First Quasars Come From?
New research shows how black holes with tens of thousands of Suns' worth of mass can form in the universe's early years.

Monstrous Black Holes Spin More Slowly — But Why?
X-ray observations add to growing evidence that the most massive black holes have a different past than their lightweight peers.
Have We Found the First Rogue Black Hole in the Milky Way?
Hubble observations have revealed a stellar-mass compact object — a black hole or possibly a neutron star — wandering our galaxy.
