The Hubble Space Telescope has revolutionized astronomy since its deployment in 1990. The telescope, which has a crystal-clear perspective of the universe and is far above rain clouds, light pollution and atmospheric distortions, has taken some stunning pictures of the most distant stars. As well as the planets in our solar system. A new image from the telescope reveals a fascinating spiral galaxy named Caldwell 5. This galaxy is about 11 million light years away from Earth. The image is notable for the galaxy’s well-defined star arms extending from its yellow center.
At the center of the Milky Way is an active star nursery capable of producing thousands of stars over a few million years.
Take a look at the image here:
Interconnected tendencies of hot gas and dust in breathtaking arms around a luminous core of stars can be seen in this gleaming, face-to-face image of the heart of the Milky Way. This core is a type of region known as an H II nucleus, which is the ionized region of atomic hydrogen. Thousands of stars can form in these intense birthplaces of stars over the course of a few million years. Each young, extremely hot blue star produces ultraviolet light, which further ionizes the gas around it, states A NASA blog post.
Caldwell 5, despite its reasonably bright 8.4 magnitude, doesn’t stand out in the sky. It is visible towards the equator of the Milky Way’s pearl disk, which is covered with thick cosmic gas, dark dust and bright stars. As a result, astronomers must stare into light-years of space full of visible obstructions to understand the complexities of the Milky Way. So, Caldwell 5 is also known as Hidden Galaxy.
Caldwell 5 would be one of the brightest galaxies in our sky if it were not hidden by so much interstellar matter. It is a small galaxy, about 50,000 light-years and billions of years old.
Caldwell 5 was discovered in the early 1890s by British amateur astronomer William Frederick Denning. states NASA. Located in the constellation Camelopardalis, Caldwell 5 is best viewed between late autumn and early winter in the Northern Hemisphere. Only people living near the equator in the Southern Hemisphere can see it low in the northern sky in late spring or early summer.
The Hidden Galaxy, as its name suggests, can be difficult to spot, especially if the sky is light-polluted or slightly foggy or hazy.
