The Dark Energy Spectroscopic Instrument (DESI) has successfully mapped the positions of galaxies within 11 billion light years of Earth, providing valuable insights into the universe’s expansion rates over time. DESI’s main focus is to measure the change in the expansion rates of the universe with time, taking into account the time it takes for light to travel from distant galaxies to Earth.
