Light from tiny galaxies over 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it today, a new study has found. Ultraviolet (UV) ...
Pasadena, CA— New work from a team of scientists including Carnegie’s Josh Simon analyzed the chemical elements in the faintest known galaxy, called Segue 1, and determined that it is effectively a fo...
