Explanation: This eagle ray glides across a cosmic sea. Officially cataloged as SH2-63 and LBN 86, the dark nebula is composed of gas and dust that just happens to appear shaped like a common ocean fish.
The
interstellar dust nebula appears light brown as it
blocks and
reddens visible light emitted behind it. Dark nebulas glow primarily in
infrared light, but also reflect
visible light from surrounding stars. The dust in dark nebulas is usually sub-millimeter chunks of
carbon, silicon, and oxygen, frequently coated with frozen
carbon monoxide and
nitrogen. Dark nebulas are also known as
molecular clouds because they also contain relatively high amounts of
molecular hydrogen and
larger molecules.
Previously unnamed, the here dubbed Eagle Ray Nebula is normally quite dim but has been imaged clearly over 20-hours through dark skies in Chile.
