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 ...

Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from RIT and Green Bank Observatory ...

The snapshot above showcases NGC 1514, a planetary nebula that resides roughly 1,500 light-years from Earth in the constellation Taurus.Despite the term, however, NGC 1514 has nothing to do with ...

One of the most spectacular is M2-9, a double-lobed beastie very roughly 2,000 light-years away. The image above was recently released, using older images from Hubble combined with a new one taken ...

As with planetary nebula M76, its discoverer, William Herschel, resolved this single bipolar object into two parts, thus the double NGC number. The southwestern lobe is NGC 2371, and the ...

This Hubble image shows ESO 455-10, a planetary nebula located in the constellation of Scorpius. The color image is composed of near-infrared and optical observations from Hubble’s Wide Field ...

Astronomers have discovered a rare celestial jewel -- a so-called Planetary Nebula (PN) inside a 500 million-year-old Galactic Open Cluster (OC) called M37 (also known as NGC2099). This is a very ...

The Hubble Space Telescope has snapped an image of a planetary nebula nested inside a star cluster. Both reside more than 10,000 light-years away in the southern constellation Pyxis. The nebula ...

A nearby planetary nebula shines like a huge golden eye in a new photo snapped by a telescope in Chile. The image shows the Helix Nebula, which lies about 700 light-years from Earth in the ...

A planetary nebula is an astronomical object consisting of a glowing shell of gas and plasma formed by certain types of stars at the end of their lives. They are in fact unrelated to planets; the ...

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." ...
