Spiral galaxy IC 342, often known as Caldwell 5, is situated roughly 11 million light-years from Earth. Hubble captured this glowing, face-on view of the middle of the galaxy, which shows intertwined tendrils of mud in spectacular arms that wrap round an excellent core of sizzling gasoline and stars.

This core is a selected kind of area referred to as an H II nucleus – an space of atomic hydrogen that has develop into ionized. Such areas are energetic birthplaces of stars the place 1000’s of stars can type over a few million years. Every younger, extraordinarily sizzling, blue star emits ultraviolet mild, additional ionizing the encircling hydrogen.

Regardless of its comparatively brilliant 8.4 magnitude, this galaxy doesn’t stand out within the sky. It seems close to the equator of the Milky Way’s pearly disk, which is crowded with thick cosmic gas, dark dust, and glowing stars that all obscure our view. This has earned Caldwell 5 the nickname of the Hidden Galaxy.

Were it not obscured by so much interstellar matter, the Hidden Galaxy would be one of the brightest galaxies in our sky. A relatively close galaxy, it is roughly 50,000 light-years across and billions of years old.
