IC410 Tadpoles

The emission nebula IC410 in the constellation Auriga. Two spermatozoa-like objects—Simeis 129 (right) and Simeis 130 (left), also known as the "Tadpoles"—each about 10 light-years long, owe their tailed shape presumably to the particle stream from the star HD 242935 at the center of the nebula. Active star formation is occurring inside the globules of the Simeis tadpoles. At the center of the nebula lies the open star cluster NGC 1893, consisting of arc-shaped chains of blue stars, likely OB-type stellar associations.
