December’s deep sky: Nebulae, clusters and more

Large, bright red cloud of gas in deep sky over a multitude of distant stars.
View at EarthSky Community Photos. | Jeremy Likness in Monroe, Washington, captured this telescopic view of the California Nebula (NGC 1499) in Taurus on December 3, 2022. He wrote: “West of the Pleiades is a red streak that spans 2.5 degrees of sky. NGC 1499 is the designation for an emission nebula that emits mostly in a set of narrow hydrogen bands. Named for its distinct shape, this is the California Nebula.” Thank you, Jeremy! See more of December’s deep sky below.

Diffuse nebulae in the deep sky

View at EarthSky Community Photos. | Kurtis Markham in Alexandria, Virginia, captured the Flaming Star Nebula (IC 405) in Auriga on December 19, 2022. His work was made under light-polluted skies, rated at class 8 or 9 in the Bortle dark-sky scale. He wrote: “The flaming star’s origin is supposedly from the nearby star nursery of the Orion Nebula.” Thank you, Kurtis!

View at EarthSky Community Photos. | Jelieta Walinski in Hickiwan, Arizona, completed this telescopic view of the reflection nebula Messier 78 in Orion on December 21, 2022. This impressive image is the result of 48 hours of integration. She wrote: “This is M78, aka NGC 2068. It is a reflection nebula in the constellation of Orion.” Thank you, Jelieta!

View at EarthSky Community Photos. | Karl Diefenderfer in Quakertown, Pennsylvania, captured this telescopic view of NGC 2264 in Monoceros. NGC 2264 is a deep-sky object comprising 2 astronomical bodies (the Cone Nebula and the Christmas Tree Cluster) on December 24, 2022. He wrote: “Merry Christmas from 2,300 light-years away in the constellation Monoceros.” Thank you, Karl!

A star cluster

View at EarthSky Community Photos. | Karrar Mohammed in Alkut, Iraq, captured this telescopic view of the Pleiades star cluster on December 17, 2022. He wrote: “The Pleiades, also known as the 7 Sisters, Messier 45 and other names by different cultures, is an asterism. It is an open star cluster containing middle-aged, hot B-type stars in the northwest of the constellation Taurus. At a distance of about 444 light-years, it is among the nearest star clusters to Earth. It is the nearest Messier object to Earth. And it’s the most obvious cluster to the unaided eye in the night sky.” Thank you, Karrar!

A supernova remnant

Swirls of orange and green nebulosity over a background of distant stars.
View at EarthSky Community Photos. | Jeremy Likness in Monroe, Washington, captured the Crab Nebula (Messier 1) in Taurus on December 15, 2022. He wrote: “In the late 1600s, comet hunter Charles Messier mistakenly observed a smudge he thought was a comet but realized it wasn’t moving. Annoyed, he started a catalog of things to avoid, and entry M1 was the Crab Nebula. This time of year, it remains high in the sky all night in the Pacific Northwest, so I took advantage of 2 clear nights to capture just over 5 hours of data. You are looking at the remnants of a stellar explosion or supernova that happened less than 10,000 years ago. The light took 6,500 years to reach my telescope.” Thank you, Jeremy!

Bottom line: Members of the EarthSky community shared these amazing photos of December’s deep sky.
