Scientists have been receiving X-ray signals from the Helix Nebula for decades, but now they believe it may hide a horrifying ...

After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: The old star might have destroyed a nearby planet. Dating back to 1980, X ...

A decades-old cosmic mystery may finally be solved. Scientists now suspect that the strange X-ray glow from a distant white ...

M57, also known as the Ring Nebula, is a planetary nebula—the glowing remnant of a sun-like star. At its center lies a tiny white dot, the star’s hot core, known as a white dwarf.

From the iconic 'Pillars of Creation' to the vivid colours of the Lagoon Nebula, check out these 7 astonishing photos of ...

This color-composite image of the Helix Nebula was created from images obtained using the the Wide Field Imager, an astronomical camera attached to the 2.2 meter Max-Planck Society/ESO telescope ...

"We might have finally found the cause of a mystery that’s lasted over 40 years." Using NASA's Chandra observatory and Europe's XMM-Newton spacecraft, astronomers may have solved a 45-year-old ...

The Helix Nebula is an eye-catching sight in the sky – and not just because it looks like a giant eye. Located about 655 light-years from Earth, it’s the site of a slow-motion explosion ...

"We think this X-ray signal could be from planetary debris pulled onto the white dwarf, as the death knell from a planet that was destroyed by the white dwarf in the Helix Nebula." An artist's ...

Dating back to 1980, X-ray missions have picked up an unusual reading from the centre of the Helix Nebula. Using today’s most powerful X-ray missions they now have a much clearer picture of this ...

Dating back to 1980, X-ray missions, such as the Einstein Observatory and ROSAT telescope, have picked up an unusual reading from the center of the Helix Nebula. They detected highly energetic X ...
