A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to ...

NASA's Hubble Space Telescope detected material from a Pluto-like body spiraling into a white dwarf star 260 light-years away from Earth. Credit: NASA / JPL-Caltech / Tim Pyle illustration For the ...

Hubble has captured a dense, burned-out star in the act of consuming a Pluto-like object. Happening some 260 light years from Earth, the new observation, published in the Monthly Notices of the Royal ...

Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering objects ...

An international team of astronomers has discovered a cosmic rarity: an ultra-massive white dwarf star resulting from a white dwarf merging with another star, rather than through the evolution of a ...

This eBook explores how energy and utilities companies can navigate critical industry challenges through digital transformation and simulation technologies. It highlights three interconnected trends ...

Some stars die quietly, ending as compact embers called white dwarfs. A rare few do something extreme, racing through the Milky Way so fast they can escape its pull, a class called hypervelocity white ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

White dwarfs — the superdense, slowly cooling embers left behind when stars like our sun die — are usually quiet cosmic relics. A rare few, however, are anything but. In recent years, astronomers ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It was super cool." White dwarfs — the superdense, slowly cooling embers left ...
