SUNSET: 
Gravitational-Wave Detections Surge with Latest Release
Astronomers have released the newest list of gravitational-wave detections, almost doubling the number of known signals from colliding black holes.
Have We Found the Black Hole Desert?
Astronomers disagree on whether they’ve found evidence that stars don’t make certain sizes of black hole.
Did Astronomers See a Star Explode Twice?
Astronomers are trying to determine if they've witnessed a complex stellar explosion or a relatively ordinary supernova.
Boosting the Gravitational Wave Background
Why is the gravitational-wave background — the hum made by supermassive black holes colliding across the universe — stronger than expected?
Scientists Release the Latest Gravitational-wave Detections
The number of gravitational-wave signals has just doubled with the release of the newest catalog of events.
New Black Hole Merger Breaks Record
Gravitational-wave astronomers have detected the collision of two beefy black holes, which created the most massive merger-made black hole found thus far.
Status Report: Gravitational Waves
Astronomers at the International Astronomical Union report that we have now detected more than 200 gravitational-wave events, most the merger of two black holes.
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.
Top 10 Astronomy News Stories of 2023
This year, we heard the low hum of gravitational waves criss-crossing the cosmos, observed a "ring of fire" solar eclipse, and applauded the arrival of asteroid samples. Here are Sky & Telescope's picks for the top news stories in astronomy this year.
The Black Hole Files with Camille Carlisle
Black Hole Rain
The planned LISA gravitational-wave detector might discover a shower of hundreds of small black holes falling in galactic centers.
Gravitational Waves from Supermassive Black Holes Revealed
Radio observatories across the globe have found compelling evidence for the existence of very-low-frequency gravitational waves.
We Could Soon “Hear” the Gravitational Waves of Dying Stars
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.
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.
The Black Hole Files with Camille Carlisle
Third Gravitational-Wave Catalog Released
The latest results from LIGO, Virgo, and KAGRA bring several key revelations, including that black holes tend to come with certain masses.
Redefining a Heavy Collision
Could the biggest — literally — gravitational-wave discovery yet be something other than what it initially seemed?
Pulsars Show Hint of Gravitational-wave Background
Duos of supermassive black holes tangoing throughout the universe make their own music, and astronomers may have picked up a hint of the tune.
Big Black Holes Dominate New Gravitational-Wave Catalog
Gravitational-wave scientists have unveiled their latest catalog of events, revealing a surprising number of massive black holes.
Record-breaking Signal Reveals New Population of Black Holes
Gravitational-wave observatories have detected the most massive black hole merger yet, and it's challenging our ideas of black hole formation.
Gravitational Wave Detectors Find Mystery “Mass Gap” Object
Astronomers have caught a black hole colliding with a mysterious companion that might be either one of the most massive neutron stars or the smallest black hole ever detected.
What Kinds of Black Hole Partners Merge?
New research on black hole mergers reveals that the black hole pairs tend to have similar masses — suggesting that they start out as massive stellar pairs.
