Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

A distant neutron star unexpectedly reawakened, unleashing a powerful X-ray surge that may reveal how the universe’s most ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, challenging astronomers to rethink how neutron stars are born and collide.

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

Astronomers have spent more than a decade watching a compact stellar remnant called P13 slip into near silence and then surge ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

The first direct detection of gravitational waves, ripples in space-time caused by the movements of massive cosmic objects, a decade ago 1 marked the start of a new era in astronomy. Gravitational ...

A rapidly spinning neutron star orbits a smaller, helium-rich star very closely. This unique pair formed when a larger star exploded, leaving behind the neutron star which then interacted with its ...
