This composite color infrared image of the center of our Milky Way galaxy reveals a new population of massive stars and new details in complex structures in the hot ionized gas swirling around the central 300 light-years. This sweeping panorama is the sharpest infrared picture ever made of the Galactic core. Credit: NASA, JPL, ESA, and Q.D. Wang (University of Massachusetts, Amherst) and S.
