Crescent Moon, Saturn and Mars Form Predawn 'Cosmic Triangle' Low in the East

The slim crescent, two days from new moon, is easiest to spot about 45 minutes before sunrise from an unobstructed eastern horizon.

Overview

  • Skywatchers get a short viewing window about 45 minutes before sunrise, with example times near 4:55 a.m. in New York, 4:36 a.m. in Boston, and 5:01 a.m. in Philadelphia.
  • All three objects sit under roughly 20 degrees above the eastern horizon, so buildings, trees, or hills can block the view.
  • Saturn appears to the lower right of the thin moon like a bright star, while Mars sits to the left with a reddish glow.
  • Experts urge people to avoid telescopes or binoculars near sunrise because a magnified glance at the sun can cause instant, permanent eye damage.
  • As Earth turns, the trio’s positions shift minute by minute, which tightens the already brief chance to see the pattern.
