﻿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2023 November 27 [2]A light brown nebula is seen on a dark starfield. The outline of the nebula makes it appear like an eagle ray fish. Please see the explanation for more detailed information. LBN 86: The Eagle Ray Nebula Image Credit & Copyright: [3]Vikas Chander Explanation: This [4]eagle ray [5]glides across a cosmic sea. Officially cataloged as [6]SH2-63 and LBN 86, the dark nebula is composed of gas and dust that just happens to appear shaped like a [7]common ocean fish. The [8]interstellar dust nebula appears light brown as it [9]blocks and [10]reddens visible light emitted behind it. Dark nebulas glow primarily in [11]infrared light, but also reflect [12]visible light from surrounding stars. The dust in dark nebulas is usually sub-millimeter chunks of [13]carbon, silicon, and oxygen, frequently coated with frozen [14]carbon monoxide and [15]nitrogen. Dark nebulas are also known as [16]molecular clouds because they also contain relatively high amounts of [17]molecular [18]hydrogen and [19]larger molecules. Previously unnamed, the here dubbed [20]Eagle Ray Nebula is normally [21]quite dim but has been imaged clearly over 20-hours through [22]dark skies in [23]Chile.
