Discovery
Tiny Galaxies Reveal How First Stars Formed

Back to article | Note about images

Color-enhanced optical image of the galaxy DDO 87 in the constellation Ursa Major showing stars.

An astronomer at Lowell Observatory studies how stars form in "dwarf" galaxies, which may provide insight into the birth of the first stars after the Big Bang. Here, a color-enhanced optical image of the galaxy DDO 87 in the constellation Ursa Major shows the stars.

This VLA radio image is of DDO 87, one of the LITTLE THINGS galaxies. The image shows integrated atomic hydrogen, the ubiquitous gas between the stars. Areas in red show the most concentrated hydrogen, an indicator of where star formation could occur.

Lowell Observatory astronomer Deidre Hunter recently presented her work on LITTLE THINGS to an audience of visitors to Lowell Observatory's Mars Hill campus in Flagstaff, Ariz. The event was part of a monthly series of talks in 2010 by Lowell astronomers designed to bring the results of astronomical research to the public.
