Description

The Tadpoles Nebula (aka IC410) - Tadpoles swim in the cosmic ocean.

This faint, dusty, emission nebula locates in the constellation Auriga about 12,000 light-years away from Earth.

The cloud of glowing hydrogen gas structures(red color) in this picture is lit by the radiation from a galactic cluster of stars NGC1893 that lies in the center of the nebula. There are two tadpole shapes in the center of the image about 10 light-years long which consist of denser, cooler gas, and dust, and it is known as the Tadpoles of IC 410.

This is a Hubble Palette (SHO) narrowband imaging that NASA tends to use RGB mapping with Sulphur II, Ha, OIII filter data.
