Mars and Uranus came as close as 1.75 degrees from each other during their January 21 conjunction. Despite the bright moon passing so near at the same time (January 20-21), our readers managed to capture a number of really great photographs on January 20, when the waxing moon was a bit fainter than the following day!
Bottom line: Mars and Uranus passed close to each other in a conjunction on January 21, 2021. Photos from the event captured by EarthSky readers available here.
Theresa Wiegert is a Swedish-Canadian astronomer with a Ph.D. in astrophysics and a master's in physics. She has loved the sky and everything in it and beyond ever since she was four years old and asked her father about the very bright star she saw one early Christmas morning. Learning it wasn’t a star but the planet Venus, she started reading anything astronomy-related she could find. Eventually she ended up as a radio astronomer, researching gas in spiral galaxies. She loves science outreach and teaching, especially showing the night sky to groups of kids (and adults!).
