Here is a HSO narrowband image of IC 443, the Jellyfish Nebula. IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation of Gemini. It is located near the bright star Propus (Eta Geminorum; the 3rd magnitude star in the bottom of the image). Read More …

Here is NGC 2174, The Monkeyhead Nebula, found in the constellation of Orion. NGC 2174 is an H II emission nebula, associated with the open star cluster NGC 2175. It is thought to be located about 6,400 light-years away from Earth. The purple glow inside the monkey’s “head” is predominantly oxygen III emissions, captured through Read More …

Here is IC 2177, a region of nebulosity that lies along the border between the constellations of Monoceros and Canis Major. The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. This latter region includes Read More …

Our first Digital Image of 2022: here is IC 405, the Flaming Star Nebula. The Flaming Star Nebula (IC 405) is a diffuse emission/reflection nebula in Auriga constellation. It surrounds the irregular variable star AE Aurigae, a runaway star believed to originate in the Orion Nebula area in the constellation of Orion. The nebula is Read More …

Here is the Rosette Nebula (Caldwell 49), an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s gas and dust. The Read More …
