Comet NEOWISE is visible in an aurora-filled sky in this photo by Aurorasaurus Ambassador Donna Lach. The photo was taken early on July 14, 2020, in western Manitoba, Canada. The purple ribbon-like structure to the left is STEVE, an aurora-related phenomenon discovered with the help of citizen scientists working with the Aurorasaurus project. The bright streak near the top of the image is a meteor.

This image of comet NEOWISE was captured by NASA’s Solar and Terrestrial Relations Observatory, or STEREO, on June 24, 2020, as the comet approached the Sun. The comet was visible in the field of view of STEREO’s Heliospheric Imager because of a special observing campaign: STEREO underwent a 180-degree roll on June 24 in order to observe the star Betelgeuse, whose brightness variations over the past several months have intrigued scientists. This image has been processed to increase contrast.
