IC410, also known as Sh2-236, has two elongated structures with a thick head on its north-eastern edge that suggested the name of Tadpoles Nebula. Recent studies, based on spectrography and photometry, likely put the whole system at a distance of about 6000 parsecs.
The size of IC410 is around a hundred of parsec; in its centers there's the open cluster NGC 1893, which light is responsible of the ionization of the surrounding gases. This cluster is made of spread new young stars, obscured by some thick molecular clouds. [Wiki] |
