Spiral galaxyIC 342, often known as Caldwell 5, is positioned 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 fuel and stars.
This core is a particular kind of area known as an H II nucleus – an space of atomic hydrogen that has turn 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 gentle, additional ionizing the encircling hydrogen.
Regardless of its comparatively shiny 8.4 magnitude, this galaxy doesn’t stand out within the sky. It seems close to the equator of the Milky Method’s pearly disk, which is crowded with thick cosmic fuel, darkish mud, and glowing stars that each one obscure our view. This has earned Caldwell 5 the nickname of the Hidden Galaxy.
Had been it not obscured by a lot interstellar matter, the Hidden Galaxy can be one of many brightest galaxies in our sky. A comparatively shut galaxy, it's roughly 50,000 light-years throughout and billions of years outdated.
