Comet C/2017 T2 makes quite the photo op as it passes by Galaxies Messier M81 and M82 in the night sky this past Sunday night, May 24, 2020, in this image taken at Grand Mesa Observatory, www.grandmesaobservatory.com. Captured and processed by Terry Hancock and Tom Masterson.

Discovered on Oct. 2, 2017 by the PanSTARRS sky survey, this comet has put on quite the show this year. Here it's seen passing about one and a half degrees away from Bode's Galaxy (M81) and the Cigar Galaxy (M82). At about 12 million light-years distant, these galaxies would take a bit longer to get to than the 13.79 light-minutes it would take you to get from Earth to C/2017 T2. Next month around June 16, C/2017 T2 will make another close rendezvous in our night sky with another Galaxy, M109, coming within a degree of it. Then, on June 23, it'll be less than one degree from Galaxy M106. It is now visible in small telescopes or decent binoculars, a nice treat to those with dark and clear skies in the Northern Hemisphere!
