For nearly a decade, scientists have been trying to understand a set of strange blue flashes coming from deep space. These ...

Teams of astronomers from several institutions have discovered a strange cosmic firework in deep space that brightened the region not just once but twice.

Rare blue cosmic explosions, called LFBOTs, could originate from the collision between a black hole or neutron star and a ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

Neutron stars are the densely compact cores remaining as one possible result of a supernova. These star remnants are ...

Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

This artist’s impression shows two tiny but very dense neutron stars at the point at which they merge and explode. ESO/L. Calçada/M. Kornmesser, CC BY Billions of light years away in a remote part of ...
