The Night Sky for July 2018

On July 27, Mars reaches its long-awaited opposition—and is visible all night. Look for its south polar cap and dark features that shift as the planet rotates. This month, you will also spot constellations Scorpius and Sagittarius, globular cluster M4, and the annual Delta Aquarid meteor shower.

Find out more about what you can see from your backyard, front stoop, or local park by viewing this monthly program. “Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope.
