Messier 76 – the NGC 650/651 Planetary Nebula

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the “little dumbbell” itself, the planetary nebula known as Messier 76!

During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake. Today, the resulting list (known as the Messier Catalog) includes over 100 objects and is one of the most influential catalogs of Deep Space Objects.

One of these objects is the Messier 76 (aka. the Little Dumbbell Nebula, the Barbell Nebula, or the Cork Nebula) a planetary nebula located about 2,500 light years away in the Perseus Constellation. While it is easy to find because of its proximity to the Cassiopeia Constellation (located just south of it), the faintness of this nebula makes it one of the more difficult Messier Objects to observe.
