A team of scientists in Australia and the United States, led by Associate Professor Miroslav FilipoviÄ“¡ from the University of Western Sydney, have discovered a new class of object which they call "Super Planetary Nebulae."  They report their work in the journal Monthly Notices of the Royal Astronomical Society.

Ring Nebula -- Discovered by Antoine Darquier de Pellepoix in 1779. The famous ring nebula M57 is often regarded as the prototype of a planetary nebula, and a showpiece in the northern hemisphere summer sky. Recent research has confirmed that it is, most probably, actually a ring (torus) of bright light-emitting material surrounding its central star, and not a spherical (or ellipsoidal) shell, thus coinciding with an early assumption by John Herschel. Viewed from this equatorial...

Dumbbell Nebula -- Discovered by Charles Messier in 1764. The Dumbbell Nebula M27 was the first planetary nebula ever discovered. On July 12, 1764, Charles Messier discovered this new and fascinating class of objects, and describes this one as an oval nebula without stars. We happen to see this one approximately from its equatorial plane (approx. left-to-right in our image); from near one pole, it would probably have the shape of a ring, and perhaps look like we view the Ring...
