Monday, July 30
9:00-11:00 pm

This summer, Mars will be the brightest and closest it’s been to Earth since 2003. On July 30, we’re pointing our telescopes toward Mars! Check out Earth’s closest neighbor through one of our ’scopes and imagine what life might be like on the Red Planet. The next time Mars will be this close is in 2035, so you won’t want to miss it! Come #Lookup with us!

This is an outdoor event only and weather permitting. The museum will not be open to guests, but restrooms will be made available. Please check this page closer to the event or follow @AdlerPlanet on Twitter for weather updates as July 30 approaches.


Can't Make it to the Adler? #LookUp Wherever You Are!

What will Mars look like?

To the naked eye, Mars will simply appear brighter in the sky. (You can’t miss it!) With a telescope, you’ll be able to see an orange-colored disc, and—depending on the strength of the telescope—you may even be able to make out some surface features! Because Mars will be so bright light pollution won’t affect its visibility much at all. (No, we’re sorry to say it won’t appear as big as a full Moon.)

In what part of the sky will Mars appear?

Starting around 9:00 pm local time from July 30-August 1, Mars will appear in the southeast sky although your local circumstances (trees, buildings, houses, etc.) will determine what time you will begin to see it. Mars will be low in the southeast, south, and southwest skies all throughout the night; at its highest point, it will be only about a third of the way up from the southern horizon.
