NASA’s newest space telescope, called SPHEREx, finally got off the ground this week, after a series of delays that had stalled its launch since late February. From low-Earth orbit, it will gather data on millions of stars and galaxies—and search for the ingredients of life.

A NASA telescope was launched into space from California on Tuesday for a mission to explore the origins of the universe and to scour the Milky Way galaxy for hidden reservoirs of water, a key ingredient for life.
