Look to the east of mighty Orion and you’ll see the constellation Monoceros, the Unicorn. While its stars are faint, Monoceros holds a small treasure chest of superb deep-sky sights for backyard stargazers. Perhaps the most striking is the Rosette Nebula, an achingly beautiful blossom of glowing gas and dust where new stars are forming. The Rosette is an immense nebula, some three times larger than the Orion Nebula and three times farther away. As you see in the image above by Terry Hancock, the nebula overlaps the star cluster NGC 2244 which has formed within the nebula and blown a bubble to give us a look inside. While hard to see the Rosette visually, even in large telescopes, the nebula is an excellent photographic target and the cluster is a superb sight [Read more…] about The Rosette NebulaShare This:
Never let a clear sky go to waste! After a quick look with binoculars at the Orion Nebula and the other features in and around the Sword of Orion, I tried to capture the same view with a quick snapshot through a DSLR. This view shows the Sword region framed against tree limbs over Washington, D.C.

In the months from late November through early March, in both the northern and southern hemispheres, the famous Pleiades star cluster grabs the attention of experienced and untutored stargazers alike. The little dipper-shaped cluster, which is about the width of your little finger held at arm’s length, takes its name from the seven sisters who were daughters of the titan Atlas and the sea nymph Pleione, but nearly every world culture has a name and legend for this group. In Sanskrit, the cluster is called Kṛttikā, which refers to the six sisters of the god Murugan. The Japanese refer to this cluster as Subaru, from which the famous car company takes its name and logo. In the middle ages in Europe, the Pleiades was associated with Halloween because it reached its highest point near midnight on that date. Legend also tells of the Pleiades reaching high into the sky on a night in 1650 B.C. when the island of Santorini in Greece exploded in a volcanic eruption and destroyed the Minoan civilization on a nearby island [Read more…] about The Merope NebulaShare This:
This marvelous image from the European Southern Observatory shows a small section of the Milky Way going about its business making new stars. Here you see in this dusty region the reflected light of a new main sequence star, HD 97300, as it settles down into its billion-year life span [Read more…] about The Dusty Birth of a New StarShare This:
The Jellyfish Nebula, also called IC 443, is the sprawling remnant of a massive star that exploded as a supernova some 3,000 to 30,000 years ago in a gas-strewn patch of the Milky Way in the constellation Gemini. As you can see in the above image by Jeff Johnson, the shock wave from the explosion produced the particularly intricate lacework of nebulosity that makes up the Jellyfish. The nebula, which is about 5,000 light years away, is adjacent to a rich region of star formation called Sharpless 249. [Read more…] about The Jellyfish NebulaShare This:
