An intermediate-mass black hole might be lurking within a dense stellar cluster — a discovery that could point toward how these oddities form.
For the first time, a team of astronomers has placed a fast radio burst on the cosmic map, allowing them to better pinpoint its mysterious origin.
From the discovery of gravitational waves to the building evidence that a massive planet could exist beyond Pluto, it has been a thrilling year for astronomy research. We recap.
Astronomer Vera Rubin, known for her revolutionary work confirming the existence of dark matter, died on December 25th. She was 88.
A team of theoretical physicists thinks a fifth force could explain an anomaly spotted in a nuclear physics experiment. If true, it could have huge ramifications for particle physics and dark matter — but that’s a pretty big if.
The gravitational wave observatory has detected a second event, heralding a new era in astrophysics. The day after Christmas last year, the cosmos quietly gifted scientists with gravitational waves — ripples in the fabric of spacetime – produced in a collision between two stellar-mass black holes. It’s the second event detected by physicists working with…
Roughly 2 million years ago, as the human ancestor homo erectus was descending from the trees, two supernovae exploded nearby and showered Earth with debris.
A brief burst of radio waves has been observed repeating, enabling astronomers to settle its exotic origin.
A radio burst with the energy of a hundred million Suns has finally been placed on the cosmic map, enabling scientists to investigate the origin of these mysterious bursts.
New images of four circumstellar disks suggest that the star formation process is much more violent than previously thought.
Ripples found in the Milky Way’s disk reveal our galaxy survived an ancient hit-and-run. Now, astronomers might have caught the culprit.
A new technique lets astronomers measure nearly invisible clouds of hydrogen gas from across the universe.
Gossip is racing around the physics and astronomy community: has LIGO finally heard its first black-hole merger? Here’s the reality.
An early peak at a forming star system reveals tantalizing clues about its origin.
Astronomers are now finding dozens of fast-moving runaway stars by searching for the bow shocks they create in interstellar gas and dust.
Unexplained ripples have been found racing through a dusty disk.
A new technique that relies on identifying stellar twins yields a novel way to measure the distances to stars.
A supermassive black hole in the early universe is at least 10 times too heavy for its host galaxy, raising questions about galaxy and black hole coevolution.
After 17 years, researchers using the Parkes radio telescope in Australia have identified the culprit behind a mysterious type of radio signal: two on-site microwave ovens.
A team of astronomers has found indirect evidence of a supermassive black hole’s event horizon, providing further proof that these wacky objects actually exist in nature.
A red dwarf and its brown dwarf companion buzzed through the outer Oort Cloud some 70,000 years ago, around the time when modern humans began migrating from Africa into Eurasia.
The best place to look for nearby Earth-size planets are around the smallest, coolest stars. New research shows that any exoplanets tightly circling their stars might have a better chance of being habitable than previously thought.
Over the course of ten years, a once-brilliant quasar seems to have stopped gobbling down nearby gas.
A newly processed image from NASA’s Galileo spacecraft shows Europa’s breathtaking beauty and tortured surface in greater detail than ever before.
Have you ever spotted the glow of a “false dawn”? Now astronomers have spotted a similar zodiacal light around nine nearby stars.
