The Tadpoles Nebula (Sh2-236) - 2025-10-24 - Hubble Palette (SHO)

            Description:
The large nebula just lower left of center is known as The Tadpoles. It is an emission nebula and a star forming region located in the constellation Auriga. It is named for the two bright streams of gas that when zoomed in resemble tadpoles. The nebula is four million years old, and is approximately 12,000 light-years from Earth. Its diameter is about 100 light-years, and each tadpole is about 10 light-years long. At the center of the nebula is an open cluster (NGC1893) that shapes the nebula and drives the Sulphur-2, Hydrogen-alpha, and Oxygen-3 (SHO) emissions.

The smaller nebula just above and right of center is known as the Spider Nebula (SH2-234).

This image records the SHO emissions using a 3-nanometer narrowband filter set. The stars are rendered in naturally colored RGB. 

This image is a single, un-mosiaced frame that was captured in a Bortle 6 suburban sky. Transparency as reported by Astrospheric was below average.
