The Iris Nebula (also known as NGC 7023 and Caldwell 4) is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487.

The Iris Nebula nebula is a damatic looking reflection nebula in the constellation Cepheus. Here;s how to find NGC 7023, and the best time to photograph it.

Nov 5, 2022 · This cloud of glowing gas is the Iris nebula, as seen in infrared light by NASA’s Spitzer Space Telescope. The main cluster of stars within the nebula is called NGC 7023. It lies 1,300 light-years away in the Cepheus constellation. Image: NASA/JPL-Caltech

Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers. Still, this deep telescopic image shows off the Iris Nebula's range of colors and symmetries, embedded in surrounding fields of interstellar dust.

The Iris Nebula has the designation NGC 7023, but is also known as Caldwell 4. NGC 7023 technically refers to the cluster of stars visible inside the nebulous gases of the Iris. The designation for the full-size nebula is LBN 487.

The Iris Nebula, designated NGC 7023 is a reflection nebula approximately 6 light years across and 1,300 light years away from Earth in the Cepheus constellation. Within the nebula, dusty nebular material (i.e.; interstellar dust and gas) surrounds a massive, hot, young star in its formative years.

Explanation: These cosmic clouds have blossomed 1,300 light-years away, in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers, though.

Oct 20, 2024 · NGC 7023 (the Iris Nebula) is located in Cepheus. Imagedx from Guelph, Ontario by Canadian astrophotographer Ron Brecher.

NGC 7023 is a reflection nebula located in the west central section of the far northern constellation of Cepheus. This nebula contains at its centre an extremely young star named V380 Cep (mag. +7.1), which is believed to have burst into life just 5,500 years ago.

NGC 7023 refers to the associated open star cluster to the west. The correct designation for the nebula itself is LBN 487.
