New research explains why some black holes are missing, showing how exploding stars stop certain black holes from forming.

When the first gravitational wave (GW) was detected back in 2015, scientists said they had opened a new window into the Universe. While most of astronomy is based on detecting electromagnetic energy, ...

A neutrino slammed into Earth in 2023 with so much energy that it looked almost unreal. The particle carried about 220 peta–electron volts, or PeV, making it the most energetic neutrino ever reported.

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

The brightest cosmic object of its kind ever detected may have helped astronomers solve the mystery of powerful, bright blue cosmic explosions. At the heart of the discovery is a signal from a ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here ...

When astronomers glimpsed the first images from the James Webb Space Telescope (JWST) in July 2022, they saw the kind of universe most of them have come to expect. There were dazzling blue bursts of ...

An international team of researchers - including experts at the Canadian Institute for Theoretical Astrophysics (CITA) in the University of Toronto's ...

The nature of black holes has long been shrouded in mystery, but some astronomers believe the answers are a lot closer to home than expected. A fringe astronomical theory known as "black hole ...

Astronomers trace a black hole outburst from its first light, reshaping theories about how these cosmic eruptions start.
