A primordial black hole may have spewed the highest energy neutrino ever found
The Big Bang may have spawned these theoretical black holes, whose lives are thought to end in a burst of extremely energetic particles.

How a Harvard maverick forever changed our concept of the stars
At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

Astronomers detect the brightest ever fast radio burst
The fast radio burst came from 130 million light-years away. That proximity allowed an in-depth search for what produced the mysterious signal.

A newborn planet munches on gas and dust surrounding its host star
In a first, astronomers imaged a baby planet within a gap in the disk of material around a star, confirming predictions about how rings form.

NASA’s Webb telescope spotted a new moon orbiting Uranus
Like Uranus's other 28 moons, the newfound object spotted by JWST will be named after a William Shakespeare or Alexander Pope character.

The Vera Rubin Observatory is ready to revolutionize astronomy
Sporting the world’s largest digital camera, the new telescope is poised to help solve some of the universe’s biggest mysteries.

A dying star revealed its heart
Before exploding, a star shed most of its layers, giving a glimpse at a massive star’s deep interior. The event may represent a new kind of supernova.

The oldest known black hole formed more than 13.3 billion years ago
The Webb telescope found that a far-off little red dot is the oldest known black hole, shrouded by gas that could help explain the ruby color.

A giant planet may orbit our closest sunlike neighbor
Alpha Centauri A, four light-years from Earth, may host a gas giant. If confirmed, no Earthlike planets orbit in the star’s habitable zone.

Seven superclouds sit just beyond the solar system
The superclouds probably produce star-forming clouds of gas, since most nearby stellar nurseries are located within the giants.

The Webb space telescope spies its first black holes snacking on stars
These star-shredding black holes sit within dusty galaxies that block many telescopes’ views. That’s not an issue for JWST.

Two colliding galaxies may have birthed this black hole
An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.
