In previous decades, the Einstein X-ray Observatory and ROSAT telescopes detected highly energetic X-rays coming from the white dwarf at the center of the Helix Nebula named WD 2226-210, located ...

The center of the nebula is home to the white dwarf WD 2226-210, the dense core of a medium-mass star, which has been the source of an astronomical mystery for decades.

The smoking gun of the creation of lithium in explosions on white dwarf stars may have been found, in a spike of gamma rays ...

A new image released by NASA shows what could be a captivating — and terrifying — event roughly 650 light-years away: a dying white dwarf that may have taken a planet out with it. The ...

Since 1980, observatories studying this nebula have detected high-energy X-rays coming from the white dwarf at its core. Since these objects don’t normally emit X-rays, the signals have stumped ...

Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.

The Owl Nebula is an example of a planetary nebula — a type of object that yields glimpses of stellar death in slow motion.

A white dwarf, or dying star, ... Dating back to 1980, X-ray missions have picked up an unusual reading from the centre of the Helix Nebula.

New data from NASA's Chandra X-ray Observatory telescope and the European Space Agency's XMM-Newton satellite has shown that a planet may have been destroyed by a white dwarf—one of the dimmest ...

At the center of the nebula is the culprit of this mystery: the small, dim remaining core of a star called a white dwarf. It is this white dwarf, named WD 2226-210 and located just 650 light-years ...

This image of the Helix Nebula, released on March 4, 2025, shows a potentially destructive white dwarf at the nebula's center; this star may have destroyed a planet. This has never been seen ...
