Members of SDSU’s student astronomy club, the Schwartz Astronomical Society, toted their telescopes and Unisteller eVscope to Mission Hills to spot a once-in-a-lifetime green comet. Fox 5 San Diego asked them their best tips for casual observers to see the comet.

Dubbed C/2022 E3 (ZTF), the comet will still be visible in the night sky with binoculars or telescopes for the next few nights in February 2023.

The comet was first discovered by researchers at Palomar Observatory and last passed earth 50,000 years ago.

Department chair, Eric Sandquist, also explained how comets provide information about the chemical ingredients of the universe.
