The planetary nebula dissipates over ~20,000 years, with only the core — a white dwarf — remaining behind. In the center of a planetary nebula, the core of a now-deceased Sun-like star heats ...

Thanks to the James Webb telescope, we can now see the nebula with more clarity. As one expert says, "We always knew planetary nebulae were pretty. What we see now is spectacular." ...

The planetary nebula K4-47 is enriched in 13C, 15N and 17O isotopes. Observations reveal that a particular planetary nebula — the ejected envelope of an old star — is unusually enriched in ...

A color composite image of planetary nebula HuBi1 reveals a low-excitation inner shell, and high-excitation outer shell, effectively appearing to be inside out. (Image credit: Nature Astronomy ...

At the heart of the double-lobed Toby Jug planetary nebula is the red-giant star HR3126, which at just 50 million years old, is considerably younger than the 4.6-billion-year-old sun. HR3126 ...

Gazing into a planetary nebula 2,500 light-years away in space may remind people the sun will eventually die, too. WIll it also go out with a light show?

The Planetary Nebula in the 500 Myr Old Open Cluster M37. The Astrophysical Journal Letters , 2022; 935 (2): L35 DOI: 10.3847/2041-8213/ac88c1 Cite This Page : ...

Other ring-shaped planetary nebulas, such as the Helix Nebula (NGC 7293 in Aquarius), have also been shown to have bi-lobed structures by which we are looking "down" the end of one lobe.

K3-35 is an emission-line nebula that contains a bipolar precessing jet, which is the origin of strong emission from N +, emanating from a bright core 5,6.These structures are embedded in an ...

The Butterfly Nebula is changing, and astronomers are puzzled as to why these changes are occurring. Observations of this planetary nebula show dramatic changes in the butterfly’s ‘wings’ in ...
