Mysterious “Little Red Dots” Give Clues to Early Black Holes’ Formation

A new look at small red galaxies known as “little red dots” reveals that they’re surprisingly abundant in the early universe.

Black Hole Sprouts Jets in Unprecedented Event

Astronomers have witnessed X-ray rumblings and a powerful plasma “burp” following a supermassive black hole’s meal.

60-second Astro News: Black Holes and Funding Woes

In this week’s roundup, astronomers wait for a decision about their next-generation megascopes, wonder if big black holes hibernated early on, and find a stellar binary in a challenging environment.

A Bubbly Origin for Odd Radio Circles

Discovered in 2019, odd radio circles (ORCs) are among the newest and most mysterious astrophysical phenomena. New research examines how bubbles blown by black hole jets could create these striking features.

Newfound Stellar Companion May Explain Black Hole System

Astronomers have identified a distant stellar tagalong to the binary system V404 Cygni.

Black Hole Eats One Star, the Remains Pummel a Second One

The crumbs of a supermassive black hole’s stellar meal has revealed the presence of a second star in a close orbit.

Black Hole's Colossal Jets Pierce the Cosmic Void

A pair of black hole jets powered by a supermassive black hole span far beyond their host galaxy — potentially affecting the cosmic web around it.

Partially Shredded Star Returns for a Second Go-round with Black Hole

A supermassive black hole has twice now grabbed gas from a passing star — and astronomers predict a third chance will come in early 2025.

No Intermediate-Mass Black Hole for Omega Centauri?

Last month, astronomers discovered a giant black hole in Omega Centauri. But it might contain a swarm of stellar-mass black holes instead.

Neutron Star Eaten by Small Black Hole (Probably)

Gravitational-wave astronomers have identified ripples in spacetime from the coalescence of a neutron star with what’s likely one of the smallest black holes ever found.

New Simulation Sheds Light on Black Hole Growth

New supercomputer simulations reveal the journey gas takes to enter a galaxy and surround and enter its black hole. That journey holds a few surprises for astronomers.

A Black Hole for Omega Centauri

The motions of individual stars in the core of Omega Centauri, a massive globular cluster, confirm the existence of a black hole at its core.

"Death Star" Black Holes Can Swivel Their Million Light-Year Long Plasma Beams

Heavyweight black holes sometimes topple over on their sides, according to X-ray and radio observations of the jets these black holes power.

Did This Black Hole Form Without a Supernova?

Some massive stars may collapse completely into black holes — without the fanfare of a supernova.

Three panels are shown showing an increasingly small area of the PRIMER galaxy field. The first image shows a large field of galaxies on the black background of space. The second image shows a smaller region from this field, revealing the galaxies in closer detail, appearing in a variety of shapes and colours. The final image shows the ZS7 galaxy system, revealing the ionised hydrogen emission in orange and the doubly ionised oxygen emission in dark red.
