A bizarre gamma-ray burst breaks the rules for these cosmic eruptions

The 50-second gamma-ray burst is the first that unambiguously breaks the rule that long bursts usually come from supernovas.

In 2022, the James Webb Space Telescope brought us new views of the cosmos

Science News looks back at some of the most stunning images from the James Webb telescope’s first year in space.

A new supercomputer simulation animates the evolution of the universe

The detailed simulation shows the cosmos changing from a dark, featureless gas to a web of stars and galaxies radiating light.

Here’s why some supermassive black holes blaze so brightly

NASA’s IPXE X-ray satellite saw a telltale signature of shock waves propagating along a blazar’s high-speed jet, causing it to emit high-energy light.

These are our top space images of all time

These are the best astronomy pictures ever, from Hubble, the James Webb Space Telescope and more.

Part of a lost, ancient star catalog has now been found

Greek astronomer Hipparchus may be the first to try to precisely map the stars. His lost work turned up on parchment that had been erased and reused.

Astronomers have found the closest known black hole to Earth

Discovered by how it pushes around a companion star, the black hole is about 1,500 light-years away and roughly 10 times the mass of the sun.

Meet the BOAT, the brightest gamma-ray burst of all time

Probably triggered by a supernova in a remote galaxy, the burst detected on October 9 could challenge theories about these brilliant blasts.

Particles from space provide a new look inside cyclones

Cosmic rays that smash into the atmosphere make muons that are sensitive to changing air pressure inside storms.

Most stars may have much more time to form planets than previously thought

Planet-making disks may survive around most young stars for 5 million to 10 million years — more than double a previous estimate.

For the first time, astronomers saw dust in space being pushed by starlight

Images collected over 16 years reveal that dust expelled from a well-known binary star system is hurried on its way by light from those stars.

A 3-D model of the Cat’s Eye nebula shows rings sculpted by jets

The Cat’s Eye is one of the most complex nebulae known. A 3-D reconstruction reveals the source of some of that complexity.
