The youngest of three neighboring clusters in the southern part of Auriga, M36 is just 25 million years old and has about 60 known members. It was discovered, with M37 and M38, by the 17th Century astronomer Giovanni Batista Hodierna.
One of three neighboring clusters in the southern part of Auriga, M38 can be found 2.5 degrees NW of M36. It is about 220 million years old and was discovered, with M36 and M37, by the 17th Century astronomer Giovanni Batista Hodierna.
IC 342 is a type-Sc spiral galaxy belonging to the Maffei 1 Group, the closest group of galaxies outside our Local Group. Were it not for the obscuring dust of our own galaxy, IC 342 would appear as the brightest galaxy in the sky.
A complex of four individual objects, NGC 2264 includes the Cone and FoxFur Nebulae, and the Snowflake and Christmas Tree Clusters. The Cone Nebula, positioned near the bottom edge of this complex, looks exactly like its name.
R Mons, a massive Herbig Ae/Be star, has created this nebula from its own accretion disk. Gas and dust are blown into a thin-walled parabolic shell that is made visible by escaping light. Rotating dust casts shadows to effect a varying brightness.
A smaller, younger cluster of about 80 member stars roughly 100 million years old, M93 has been noted to look like a starfish, a butterfly, and a triangle. This cluster has a linear diameter of 20-25 light years and includes several blue giants.
This 500 member cluster is about 300 million years old. The planetary nebula NGC 2438, most apparent in the high-mag view, is an unrelated, evolving star some 1500 light years closer and several hundred million years older.
Though discovered by Giovanni Hodierna in the 17th Century, and re-discovered by both Charles Messier and William Herschel a century later, this cluster was considered 'missing' until it was officially identified by TF Morris in 1959.
About five-hundred stars reside within this 'ancient' cluster, including two-hundred white dwarfs and more than one-hundred sun-like stars. At four-billion-years, M67 is nearly as old as our Solar System.
