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

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.

Powerful jets and radiation winds from two protostars are slamming into the nebulosity around them, sculpting the nebula.

A decades-old cosmic mystery may finally be solved. Scientists now suspect that the strange X-ray glow from a distant white dwarf is the result of a planet being ripped apart and devoured by the dying ...

This stunning image features a deep field view of the Cassiopeia constellation where the two small planetary nebulas can be found, Abell 6 and the larger HFG1.

Planetary nebula are some of nature's most stunning visual ... dust-rich molecular ring (Ring 2)—detected in (dust) absorption, in low-excitation emission lines, in H 2, and (now) in 12 CO ...

The Necklace Nebula, formed by two doomed stars, glows with bright gas clumps like a cosmic diamond ring. Located 15,000 light-years away in the Sagitta constellation, it shines as a stunning ...

This bright planetary — magnitude 9.7 is bright ... A magnitude 10.2 star lies a bit more than 2″ east of the nebula. A big neighbor This week’s second large-telescope target is barred ...

Using the James Webb Space Telescope (JWST), astronomers have observed enigmatic rings in the planetary nebula NGC 1514, visible in the mid-infrared band. Results of the new observations ...

ABSTRACT Bipolar, elliptical, and circular planetary nebulae appear to be possessed of differing Galactic scale heights, a feature which is usually assumed to arise from the differing distributions ...

ABSTRACT Up to now, 10 planetary nebulae have been regarded as halo planetary nebulae (halo PNe). We obtained low‐ and moderate‐dispersion spectra of the spatially resolved halo planetary nebula H4‐1 ...
