Pitt team used Sloan Digital Sky Survey to determine that the merger of double white dwarfs is a plausible explanation for Type Ia supernovae.

Astronomers from University of Pittsburgh seeking to find the true color of our very own Milky Way have revealed that it is so white that it would resemble a fresh blanket of snow to the naked eye.

Berkeley Lab scientists and their Sloan Digital Sky Survey colleagues use galactic brightness to build a precision model of the cosmos.

The Milky Way galaxy continues to devour its small neighboring dwarf galaxies and the evidence is spread out across the sky.
