Dark Energy Spectroscopic Instrument lenses get their first look at space
Scientists are one step closer to precisely 3D mapping the galaxy and better understanding dark energy. For years, a team of more than 70 international organizations have been building the Dark Energy Spectroscopic Instrument (DESI), which will allow us to see the sky in a way we never have before. Earlier this week, DESI reached a "first light" milestone when scientists produced the first focused images with the instrument's precision lenses. The images show the Whirlpool Galaxy -- an estimated 23 million light years from Earth.
