Many more planetary nebulae await you in Cygnus the Swan. Download this table for detailed information about 53 planetaries, including where to find them and how they are classed.

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 ...

Something is amiss in the Butterfly Nebula. When astronomers compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic ...

An amateur astronomer discovered the planetary nebula, which is known as Kronberger 61. NASA's Kepler Space Telescope will look at the object to see if it has a companion object, be it another ...

The nebula, called HuBi 1, is strange, but it doesn’t defy the laws of physics—it’s a case of a planetary nebula surrounding a dim star that seems to have awaken on its way to death ...

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 ...

The European Southern Observatory has captured an image of a galactic phenomenon known as a planetary nebula. The beautiful colors of ESO 577-24 come from a shell of glowing ionized gas around the ...

The unique planetary nebula NGC 2818 is nested inside the open star cluster NGC 2818A. Both the cluster and the nebula reside over 10,000 light-years away, in the southern constellation Pyxis (the ...

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 ...

The sands of time are running out for the Sun-like star at the centre of this spectacular planetary nebula called the Engraved Hourglass Nebula MyCn18.
