Cosmic Dawn: The First Star in the Universe

Celebration of SSRL’s 50th Anniversary, group photo held on main quad on April 20, 2023.

In this conceptual art, an electron and positron collide, resulting in a B meson (not shown) and an antimatter B-bar meson, which then decays into a D meson and a tau lepton as well as a smaller antineutrino.

When stars explode, the supernovas send off shock waves like the one shown in this artist's rendition, which accelerate protons to cosmic-ray energies through a process known as Fermi acceleration.
