Astronomers who use NASA Hubble Space have taken a stunning new image of part of a spiral galaxy called NGC 45.
This image displays Hubble to NGC 45, a spiral galaxy, about 22 million light -years away in the CETUS constellation. The colorful image of separate exposure to UV, visual and close to infrared radiation is manufactured with the Hubble’s Wide Field 3 (WFC3). It depends on the data obtained through seven filters. The color is caused by the appointment of different shapes for each monochromatic image associated with an individual filter. Credit Image: Nasa / Esa / Hubble / D. Calzetti / R.

NGC 45 It is about 22 million light years in the CETUS constellation.
Also known as DDO 223, ESO 473-1 or LEDA 930, this galaxy is present 81,000 light years Air.
NGC 45 was discovered by English astronomer John Hershel on November 11, 1835.
“The Hubble data used to create a NGC 45 image of two complementary programs has been extracted,” Hubble astronomers said in a statement.
“The first took a wide view of 50 nearby galaxies, as it benefited from Hubble’s ability to monitor light from UV rays to infrared near to study the formation of stars in these galaxies.”
“The second program studied many nearby galaxies, such as the first, and narrowed along a specific wavelength of the red light called H-Alpha.”
“The stars, the stars are powerful for the H-Alpha light, and many of these areas can be recognized via NGC 45 by their bright red color.”
“These monitoring programs aim to study the formation of stars in galaxies of different sizes, structures and isolation – and NGC 45 makes a particularly interesting goal.”
Although it may seem to be a regular spiral galaxy, NGC 45 is actually a great type called a Low surface brightness galaxy.
The researchers said: “Low surface brightness galaxies are dim from the sky of the night itself, which makes it difficult to discover them incredibly.”
“It seems unexpectedly pale because they have a relatively few stars for the amount of gas and dark materials they hold.”
“In contracts that have passed since the first brightness of low brightness, a superficial galaxy was discovered in 1986, and the researchers have learned that 30-60 % of all galaxies may fall into this category.”
“The study of these galaxies, which is difficult to discover, is the key to understanding how to form galaxies and develops, and sensitive Hubble tools equal to the task.”
