Object Details

IC 410 / NGC 1893
NGC 1893
refers to a small open star cluster in the Auriga constellation. IC 410 describes the associated HII region. It is assumed that the region is approximately 4'500 light years away from Earth.

The nebula was named the Tadpole Nebula because of the two gas globules, which look as if they are swimming towards the centre of the nebula. The Hubble Space Telescope was first able to confirm this phenomenon conclusively. The image that was published at that time is now the world-famous image "Pillars of Creation" (Eagle Nebula). These gas globules are probably predecessors of protostars. Gravity pulls the nebula cloud together, increasing the heat and density. Depending on how much mass is present, a star is formed according to the HR diagram.
