The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our Sun," according to NASA/ESA. Credit: NASA, ESA, P. McGill (Univ. of ...

However, upcoming gravitational wave observatories like NASA's space-based detector LISA ... a tightrope-walking white dwarf with a mass of about 10% of that of the sun's. In this scenario ...

Astronomers are baffled by EP240408a, a rare cosmic explosion that defies explanation, sparking theories of a black hole and ...

The light output of exploding white dwarf stars, which are the stellar corpses of stars with masses around that of the sun, is so uniform that astronomers can use it to measure distances.

The flash was spotted by the Einstein Probe’s Wide-field X-ray Telescope (WXT), which uses a novel type of design known as a lobster eye that can scan 3,600 square degrees simultaneously using 432 ...
