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

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 ...

Neutron stars pack extreme mass into tiny volumes. Scientists explore how compact they can become before collapsing into ...

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

A couple months back, astronomers officially confirmed the existence of “Betelbuddy,” Betelgeuse’s long-suspected companion ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

The federal government has been—and must remain—a critical partner in foundational technological innovation and research ...

For over a decade, a dim but persistent glow near the center of the Milky Way has confused astronomers. This mysterious ...

The universe is a strange place. The X-ray Imaging and Spectroscopy Mission (XRISM) orbiting observatory recently highlighted ...

A discovery involving researchers at The University of Hong Kong (HKU) has, for the first time, revealed millisecond pulsations hidden within a powerful cosmic explosion known as a gamma-ray burst ...
