Comet C/2017 T2 PANSTARRS Meets Up With Messier 106

Another collaboration between Tom Masterson and Terry Hancock in this image taken at Grand Mesa Observatory, Comet C/2017 T2 takes another photo op as it passes by Galaxy Messier 106 (M106) in the night sky this past Tuesday night, June 23, 2020.


Discovered on Oct. 2, 2017 by the PanSTARRS sky survey, this comet has put on quite the show over the past couple months. Here it's seen passing within a degree from M106, a very close and beautiful event. While they might look really close to each other in this image If you were travelling at the speed of light it would take between 22 to 25 million light-years to reach M106 but only 14.5 light-minutes to reach Comet C/2017 T2.


Messier 106 is an intermediate spiral galaxy located in the constellation Canes Venatici and It’s is one of the largest and brightest nearby galaxies similar in size and luminosity to the Andromeda Galaxy.
