Shortly after the birth of the universe, space was filled by a plasma that was literally red-hot. The light radiated by that plasma has traveled the vast emptiness of space for billions of years, with the expansion of the universe slowly stretching its waves until today it appears as microwave radiation. This is the Cosmic Microwave Background (CMB), a glow still visible in the night sky. This glow is almost uniform, but small variations from point to point hold information about the conditions of the universe 13.8 billion years ago.
After viewing the previous public lecture by SLAC staff scientist Zeeshan Ahmed on the CMB and its measurement, get an update on our plans for studying it with a new observatory called CMB-S4 from remote outposts near the South Pole and in Chile's Atacama Desert, during the live virtual Q&A.
