A smaller white dwarf star (left) pulls material from a larger star into a swirling accretion disk in this artist's concept released Nov. 19, 2025, to illustrate the first use of NASA's IXPE (Imaging ...

Using ESO’s Very Large Telescope (VLT), astronomers have captured a breathtaking shock wave around the white dwarf star 1RXS J052832.5+283824 (RXJ0528+2838 for short) — a phenomenon that doesn’t fit ...

This artist’s concept depicts a smaller white dwarf star pulling material from a larger star, right, into an accretion disk. Earlier this year, scientists used NASA’s IXPE (Imaging X-ray Polarization ...

A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to several hundred of years. The remnant is located in the "Large Magellanic ...

Hubble spots white dwarf star 'snacking' on chunk of Pluto-like object. The NASA/ESA Hubble Space Telescope has spotted a white dwarf star devouring a piece of a Pluto-like object. The star is about ...

White dwarfs are the dense remnants of stars and operate as cosmic labs for astronomers. When these white dwarfs collect enough material from a companion star, they can explode as a Type Ia supernova ...

What can white dwarf stars eating their own planets teach astronomers about planetary and solar system formation and evolution? This is what a recent study published in The Astrophysical Journal hopes ...

Astronomers have spotted a white dwarf devouring a planetary remnant billions of years after its death, revealing unexpected late-stage activity in planetary systems' afterlife. The star in question, ...
