Triangulum, also called Messier 33, can be spotted by lucky skywatchers without an assist from a telescope, but it looks like a smudge.
Study author Julianne Dalcanton of the University of Washington in Seattle, said, 'My first impression on seeing the Hubble images was, wow, that really is a lot of star formation.
ESA says the Triangulum image is the second-largest ever released by Hubble and will help astronomers better understand how stars form and evolve.More news: Trump threatens to withhold FEMA money from California to help with wildfires
Under excellent dark-sky conditions, the Triangulum Galaxy can be seen with the naked eye as a faint, blurry object in the constellation of Triangulum (the Triangle), where its ethereal glow is an exciting target for amateur astronomers. By comparison, the Andromeda Galaxy is 200,000 light-years across and the Milky Way is 100,000 light-years in diameter.
The runt of the litter also lacks the conventional bright bulge at its heart and does not have a bar connecting its spiral arms to the center.
But in a new 665-million pixel image taken by the NASA/European Space Agency (ESA) Hubble Space Telescope, the spiral galaxy's billions of stars are brightly showcased. "Most notably, Triangulum's star formation is 10 times more intense than in the comparable Hubble panorama of the neighboring Andromeda galaxy". If it were oriented with its side facing us we'd have a much harder time picking out the millions of individual stars that make up its spiral shape. That huge amount of gas and dust allows for rapid star formation, at a rate of approximately one solar mass every two years.More news: Carlos Ghosn appears in court to challenge his detention
The abundance of gas clouds in the Triangulum Galaxy is precisely what drew astronomers to conduct this detailed survey.

Which is freakish, because newborn stars devour dust and gas, leaving less fuel for new celestial bodies to emerge.More news: Alisson turned down Chelsea for Champions League football
The Triangulum Galaxy, also known as Messier 33, belongs to the Local Group - a gravitationally bound collection of more than 50 galaxies that includes the Milky Way and the nearby Andromeda Galaxy.
