Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

Thousands upon thousands of stars illuminate this breathtaking image of star cluster Liller 1, imaged with Hubble’s Wide Field Camera 3. This stellar system, located 30,000 light-years from Earth, ...

This jagged jumble of pixels may look like a rainbow-colored thunderbolt, but it’s actually a spectrum of light gathered by the Hubble Space Telescope that shows the swirling motion of gas and stars ...

This work focuses on the development of a state-of-the-art gravitational lensing code we dubbed SMILE (Self-lensing Model Involving Limb-darkened Ellipsoidals) with wide application across the black ...

The discovery of gravitational waves in 2015 – already postulated by Einstein one hundred years ago – led to the 2017 Nobel Prize in Physics and initiated the dawn of gravitational-wave astronomy.

The carbon fusion reaction, in which two 12C nuclei combine under extreme stellar conditions, is of paramount importance in astrophysics. This process not only dictates the evolution of massive stars ...

HONOLULU — Celestial objects that glow with steady, eternal light powered not by nuclear fusion like our sun, but by dark matter — the invisible substance that makes up most of the universe — may ...
