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 ...

In this image from NASA's Spitzer Space Telescope, "cometary knots" on the Helix Nebula show blue-green heads caused by excitation of their molecular material from shocks or ultraviolet radiation.

The Anker Nebula Cosmos 4K SE (not to be confused with the older Cosmos Laser 4K) looks more like a tall car battery with a handle on top than the usual cube that's typical of room-to-room ...

The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula's eerie interior bluish glow. The Bubble Nebula is 7 light-years across and resides 7,100 ...

Helix Nebula: This a planetary nebula, which is formed when a star like the Sun runs out of fuel, expands and its outer layers puff off, and then the core of the star shrinks. Orion Nebula ...

"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 ...

The signal, which scientists have been working to untangle for more than 40 years, is thought to be the "death knell" of an exoplanet destroyed by a star in the Helix Nebula. Astronomers first ...
