Despite being only 10% into its five-year mission, the Dark Energy Spectroscopic Instrument (known as DESI) has already mapped more than 7.5 million galaxies as it looks up to 10 billion light-years away. Ultimately, DESI intends to scan 40 million galaxies across a third of the sky. Thus far, scientists have used this data to learn about the way the universe is expanding and how quickly, as well as how it all pertains to the mysteries of dark energy.
