Skywatching This Weekend: July 11-14

Mars Speeds Past Spica

This weekend, try and observe Mars as it passes near the bright star Spica. Notice too the color difference: Mars is a bright orange-red planet and Spica is a blue, twinkling star.

If you have been watching Mars this summer, you have seen it get closer and closer to Spica. This Saturday, Mars will come closest to Spica, and then it will begin to pull away to the west. The GIF below (images from Stellarium) shows the southwestern sky at 9:30 pm Central time from Friday to Monday night. Notice how Mars moves past Spica.

Saturn is to the left of the pair, and Mars will be in good view throughout the summer.
