2020, January 21: Mars, Moon, and Antares

Advertisements

During a cold, clear morning in the Chicago area, the planet Mars is about 5 degrees to the upper left of the star Antares, the Red Planet’s rival.  The star is about the same color and brightness as Mars when the planet passes by about every 2 years.

This morning the old moon (overexposed in the image above) appears to the lower left of the Mars-Antares pair.  Notice that the night portion of the moon is gently illuminated by the sunlight reflected from our planet.
