The summer solstice on June 21 may be an important annual observance on Earth, but aside from the sun being its highest in the sky in the Northern Hemisphere, it's not typically a stargazing event. That changes in 2023 with the appearance in the solstice's evening twilight of Venus, Mars and a slim crescent moon in the western sky.
The three celestial bodies won't appear this close together again to observers in North and South America until March 28, 2028, according to When The Curves Line Up. With alignments also appearing on the evenings before and after the solstice, it's a great week to be outside in twilight, with the added bonus of Da Vinci glow — or Earthshine, sunlight reflected by the Earth onto the dark lunar surface — visible on the waxing crescent moon.
