IC 410, the Tadpoles Nebula - BBC The Sky At Night "is located 12,000 lightyears from Earth in the Auriga constellation, and is nicknamed the Tadpole Nebula because of the tadpole-shaped clouds of dark dust that appear to be swimming towards the centre. The Tadpole Nebula is a region of ionised hydrogen gas spanning over 100 lightyears across that's carved and sculpted by streams of charged particles called stellar winds emanating from open star cluster NGC 1893. NGC 1893 is about 4 million years old: the blink of an eye in cosmic terms. The 'tadpoles' that give the nebula its nickname are dense streams of dust and gas about 10 lightyears long that may well be sites of star formation."
