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.

NASA’s DART mission successfully shoved an asteroid

Data obtained since the spacecraft intentionally crashed into an asteroid show that the impact altered the space rock’s orbit even more than intended.

The James Webb Space Telescope spied the earliest born stars yet seen

The stars, found in the first released science image from the James Webb Space Telescope, probably winked into existence about 13 billion years ago.

NASA’s DART spacecraft just smashed into an asteroid — on purpose

If the first-ever attempt to knock a space rock off course works, it could provide a blueprint to protect Earth from a killer asteroid.

Here is the first direct look at Neptune’s rings in more than 30 years

In 1989, the Voyager 2 spacecraft took the first pics of Neptune’s rings. Now, NASA’s James Webb Space Telescope is providing a more detailed look.
