IC 405, IC 410 & IC417 - Nebulas in Auriga

2020

May 4

One of the most beautiful paintings that our sky allows us to admire in photography.
In this image we can see IC405, a nebula that can only be admired well in photos, placed at 1630 light years from us and illuminated by a variable star, AE Aurigae. This star ionizes the gases of the nebula giving it the red color.

Below and in the center we find IC410, also an emission nebula, this time however the gases are ionized by an open cluster of stars, NGC 1893. It is also called the Tadpole Nebula due to two filaments in which there are large formation processes stars that look exactly like tadpoles. It is 19640 light years from us.
The third nebula has the initials IC417 is also called Spider Nebula, and this time the typical red color due to ionized gas is caused by the open Stock 8 cluster. It is 7500 light years away.
From the distances it can be understood that IC410 is the largest nebular area of the three, being at a distance of more than ten times greater than IC405, while in the photo, for obvious reasons, they appear on the same plane.
