Header Image: While C/2019 Q4 (Borisov) is too far away for us to get detailed images, it probably looks something like this image taken on March 27, 2016, by the Rosetta spacecraft, 329 km from the nucleus of Comet 67P/Churyumov-Gerasimenko. The image measures 28.7 km across. Image Credit: ESA/Rosetta/NavCam The Day the Adler Met an […]

Every summer, Michelle Larson, President and CEO of the Adler Planetarium, loves to attend a star party (or two!) with her family. Star parties are one of those scenarios where groups of people get together and camp out in a place where the night sky is highly visible. People bring tents, blankets, hot chocolate… and […]
