Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.

This new James Webb Space Telescope image features a cosmic creepy-crawly called NGC 6537–the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), JWST has revealed never-before-seen details in ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

In the 10 years since the first detection of gravitational waves, we have detected hundreds of these waves produced by the ...

The universe is a strange place. The X-ray Imaging and Spectroscopy Mission (XRISM) orbiting observatory recently highlighted ...

JWST found a carbon-atmosphere planet orbiting a pulsar, challenging current models of how planets form. Scientific progress often comes from data that don’t fit our current understanding. This idea, ...

Where does gold really come from? It turns out that the glittering metal on Earth has its roots in violent cosmic events — ...

A kilonova formed by colliding neutron stars releases gamma ray bursts powerful enough to vaporize atmospheres within a ...

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

A couple months back, astronomers officially confirmed the existence of “Betelbuddy,” Betelgeuse’s long-suspected companion ...

In the 1960s, the United States, the United Kingdom, and the Soviet Union signed a treaty banning nuclear weapons tests ...
