Space Scientists Study Galactic Nursery Using Hubble Space Telescope

Irregular galaxy NGC 1140 starbursts at same rate as larger Milky Way

 Smaller irregular galaxies like NGC 1140 are of interest to astronomers studying the first galaxies to appear in our universe some 13.7 billions years ago because their composition is thought to be similar in nature to the early galactic building blocks that combined to make galaxies like our Milky Way.

Space news (July 29, 2015) – 60 million light-years away in constellation Eridanus

NASA space scientists recently viewed the dwarf galaxy NGC 1140 undergoing starburst, an intense, but brief period of star formation believed to be characteristic of the first galaxies born in the universe billions of years ago. 

Astronomers estimate during this starburst NGC 1140 will spawn a star like Sol every year, but knowledge concerning possible star-forming rates during starburst is rudimentary at this point. The bright, blue-white regions in the image above indicate the presence of young stars made up primarily of hydrogen and helium and fewer heavy metals than stars like Sol.

NASA space scientists plan on studying this irregular galaxy to gather data and facts concerning the evolution of the first galaxies to appear in the universe. The first galaxies born in the universe are much more distant in space-time, than galaxies like NGC 140, and therefore much harder to study. Studying this starburst is an opportunity for space scientists to learn more about the first galaxies to appear in the universe, without having to make a 13.77 billion year trip to the beginning of spacetime.
