Could an ocean – likely needed to sustain life – even survive on a planet orbiting close to a dead star? The sun will someday ...

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 has uncovered a rare ultra-massive white dwarf created in a violent star merger. Once thought to be ordinary, the star ...

In a breakthrough study published in Nature Astronomy, researchers have discovered a new origin for some of the fastest stars ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It ...

Astronomers discovered a rare ultra-massive white dwarf forged in a stellar smash-up and unmasked only by Hubble’s ultraviolet vision.

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

The Hubble Space Telescope of the National Aeronautics and Space Administration (NASA) recently published a study in the journal Nature Astronomy, where astronomers discovered an unusual white dwarf ...

A white dwarf is a small, dense remnant left behind after a star dies, still emitting heat even after it has burned out. Some planets may orbit around it, close enough to remain warm, and potentially ...

A key mystery about Type Ia supernovas is that, in the dominant theory known as D6, a white dwarf would need a companion star ...

Galaxies, Auroras, the Moon, our Sun, planets and more – the Royal Observatory Greenwich reveals the winners of the ZWO ...
