New images of a "born-again" planetary nebula give a glimpse of what our sun might look like in 5 billion years when it transforms into stellar giant near the end of its life cycle.Scientists ...

Abell 33 is just one of the 86 objects included in astronomer George Abell's 1966 Abell Catalogue of Planetary Nebulae. Abell also scoured the skies for galaxy clusters, ...

100 Planetary Nebulae (to scale) (Image Credit: Judy Schmidt/NASA). The name "planetary nebula" might indicate planets are somehow involved, when it is actually a reflection of the way these ...

To appreciate how age can affect the apparent size of a planetary nebula, try sighting Abell 21, the 8th-magnitude so-called Medusa Nebula in Gemini.

This beautiful cosmic object is a planetary nebula named Abell 24, captured by the European Southern Observatory's Very Large Telescope (VLT). Located in constellation of Canis Minor (The Lesser ...

The term planetary nebula is a misnomer; early astronomers mistakenly thought these objects to be planets. The symmetry of Abell 39, one of the largest such spheres ever discovered, enables scientists ...

Astrophotographer Bob Franke captured this stunning image of planetary nebula Abell 39 6,800 light-years away from Earth. See how Franke made the image here.

Abell 39, the 39th entry in a catalog of large nebulae discovered by George Abell in 1966, is a beautiful example of a planetary nebula. <P> It was chosen for study by George Jacoby (WIYN ...

Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33. Created when an aging star […] ...

New images of a "born-again" planetary nebula give a glimpse of what our sun might look like in 5 billion years when it transforms into stellar giant near the end of its life cycle.

At present, there is a disagreement among astronomers about the exact chemical make-up of dying stars that produce these planetary nebulae. Abell 39 may help solve this problem.
