The countdown for the year's first (and only) total lunar eclipse begins. The celestial event, which will see the moon change to rusty red hues, will occur in the U.S. on the night of March 13-14.

Without protective gear, looking directly at an eclipse can cause serious damage or scarring to the eyes. “Solar retinopathy is a photochemical injury to your retina,” Dr. Nicole Bajic, a surgical ophthalmologist at the Cleveland Clinic, previously told TIME via email.

Sometimes sleep takes priority over cool celestial events. Luckily, you can catch a partial solar eclipse this month and a blood moon again in 2026.
