The Science daily today said that the NASA/ESA Hubble Space Telescope has imaged the faint irregular galaxy NGC 3738, a starburst galaxy.
“The galaxy is in the midst of a violent episode of star formation, during which it is converting reservoirs of hydrogen gas located in the galaxy’s center into stars. Hubble spots this gas glowing red around NGC 3738, one of the most distinctive signs of ongoing star formation”,said the same journal.
The journal further said :”Lying in the constellation of Ursa Major (The Great Bear), NGC 3738 is located about 12 million light-years from the sun, and belongs to the Messier 81 group of galaxies. This galaxy — first observed by astronomer William Herschel back in 1789 — is a nearby example of a blue compact dwarf, the faintest type of starburst galaxy. Blue compact dwarfs are small compared to large spiral galaxies — NGC 3738 is around 10,000 light-years across, just one tenth of the size of the Milky Way.”
