The Dark Energy Spectroscopic Instrument (DESI), currently pointed at the skies from its home in the Nicholas U.

The main objective of DESI is to reveal more about the dark energy that is thought to make up 70 percent of the Universe as well as speeding up its expansion.

This dark energy could drive galaxies into an infinite expansion, cause them to collapse back on themselves or something in between – and cosmologists are keen to narrow down the options.

The best way to spot a black hole is to identify the gas, dust, and other material being dragged into it, but that's not easy to see in smaller galaxies – something that the high-precision spectra data collected by DESI should help with.
