A new study suggests the Milky Way’s gamma-ray glow could be a dark matter signal shaped by ancient galactic mergers.

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 ...

Space has a way of making scientists throw out their textbooks. Just when astronomers think they understand how the universe ...

By developing a new theoretical relation describing just how compact neutron stars — which are the remnants of massive stars ...

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 ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of ...

An excess of gamma rays in the center of our galaxy could mean scientists have finally detected dark matter particles—or not ...

New research from Johns Hopkins University and an international team of scientists suggests that two competing theories for ...

Stars often fall into black holes, and now it seems the opposite can also occur, producing an extra long-lasting explosion as the star is consumed from within ...

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...

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 ...
