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.
