According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here's how they plan to crack the case.

Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or neutron star slams into the universe's hottest class of star.

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

Shock waves from tiny black holes in the early universe could explain how antimatter became so rare while matter is common.

An international team led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has developed a new method that could significantly improve our understanding of the ...

The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed.

We all know that everything kicked off when the Big Bang exploded our universe into reality, right? Well, not necessarily. A compelling new theory of the creation of our universe suggests that it may ...
