First Light: Cosmic Viewer

The oldest light in the universe, now in the palm of your hand.

Look up. What you're seeing isn't the night sky. It's the afterglow of the Big Bang, captured by three of the most important space missions ever launched.

First Light turns real cosmic microwave background data from COBE, WMAP, and Planck into an immersive sky you can explore by simply moving your phone. Pan across the oldest light in the universe. Switch between satellites. Dial through frequency bands and watch the universe shift.

This is real data. Real science. And it fits in your pocket.
