A wisp of a galaxy is rich with new, blue-white young stars and primordial gas in this new cosmic photo from the Hubble Space Telescope.
The irregular dwarf galaxy is creating stars the size of our sun at a prodigious rate of about once a year. That's the same speed of star creation as our own Milky Way, but from a galaxy that is one-tenth the size.
The dwarf galaxy, called NGC 1140, is located about 60 million light-years away in the constellation Eridanus (the River). Scientists are interested in this type of galaxy because it harks back to the earliest galaxies in the universe, formed of mostly hydrogen and helium and building new stars at a frantic pace in a process called "starbursting." From those early galaxies, large modern star systems eventually blossomed — and by studying their contemporary counterparts researchers get a glimpse of galactic evolution.

But alas, the celestial fireworks of NGC 1140 won't last forever.
"The vigorous star formation will have a very destructive effect on this small dwarf galaxy in its future," European Space Agency officials wrote in an image description.
As the galaxy's largest stars explode into supernovas, they will blow the star-creating gas away into space — "throwing out its potential for future stars," officials said. "NGC 1140's starburst cannot last for long."
