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

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 ...

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

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 ...

NASA’s Hubble Telescope has uncovered WD 0525+526, a rare ultra-massive white dwarf formed in a violent star merger.

When the biggest geomagnetic storm in 20 years hit Earth in May 2024, photographer Kavan Chay was in Tumbledown Bay, New ...

White dwarfs may still host habitable planets. Conditions like tidal heating and migration shape their potential for life. The Sun will eventually die. This will occur when it exhausts the hydrogen ...

Astronomers have detected an explosion of gamma rays that repeated several times over the course of a day, an event unlike ...
