The first-ever baby pictures of a solar system that’s not our own are finally here—and they’re beautiful—and as adorable as space entities can get. In a paper published today in Nature, astronomers presented HOPS-315: a Sun-like protostar cooking up a brew of hot minerals and silicon monoxide gas, located about 1,300 light-years away from Earth. […]
Astronomers Detect a Black Hole Merger That’s So Massive It Shouldn’t Exist
Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to reach our own detectors here on […]
Physicists Propose Cheaper Alternative to Particle Colliders: Supermassive Black Holes
A new study from Johns Hopkins University suggests that supermassive black holes—those cosmic behemoths lurking at the centers of galaxies—might already be generating the kinds of high-energy particle collisions researchers have spent decades trying to recreate here on Earth. Published today in Physical Review Letters, the study proposes that certain spinning black holes could serve […]
A Rogue Black Hole of Unusual Size Is Devouring Stars in a Distant Galaxy
Astronomers have spotted an apparent supermassive black hole snacking on a star 600 million light-years away, wandering through a galaxy with an even larger black hole at its core. The event, dubbed AT2024tvd, was first spotted by the Palomar Observatory’s Zwicky Transient Facility and later confirmed by powerhouse space telescopes including Hubble and Chandra, which […]
An Asteroid Has a 1-in-63 Chance of Hitting Earth in 2032—Here’s What That Means
Odds are a funny thing. 1-in-100, for example, sounds like a long shot—until you find out it’s the chance that an asteroid will impact Earth. In a surprising—but not definitive—turn of events, early warning systems this week found that an asteroid set to swing by Earth in 2032 has a 1-in-63 chance of smashing into […]
New Asteroid Tops NASA’s Impact Risk Chart, 1.2% Chance of 2032 Collision
2024 YR4 is a newly spotted asteroid with the potential to hit Earth—and its chances of smashing into our planet in 2032 is definitely more than zero. I realize that “definitely more than zero” will cause some disquiet in the comments, so to be specific: There is a 1.2% chance the asteroid hits Earth based […]
Mysterious Radio Bursts Traced to the Edge of an Ancient, Dying Galaxy
In February 2024, scientists on Earth detected a powerful radio blast from outer space. Seeking to discover where it had come from, they traced the brief flash of energy back to its extraterrestrial source—and discovered something unexpected. Scientists led by Northwestern University and McGill University have traced a fast radio burst (FRB) to the edges […]
