Tonight's Stellar Spectacle

Get ready for a breathtaking celestial display this evening! On Monday, June 16, Mars will glide a mere 0.8° away from the brilliant star Regulus at midnight EDT, giving skywatchers an ideal opportunity to witness a cosmic duet.

How to Spot Mars and Regulus

As the sun dips below the horizon, turn your gaze westward and you’ll see these two luminaries positioned closely in the sky. Mars will twinkle just above the right side of Regulus, both shining with the same magnitude, but their colors will make them stand out. Regulus, a scorching hot blue-white star, boasts a staggering temperature of about 15,400 kelvins—over twice as hot as our Sun! In contrast, Mars radiates a warm orange-red hue, a result of sunlight reflecting off its rusty surface.
