Mars, Saturn and a Thin Crescent Moon Form Predawn ‘Cosmic Triangle’

A New Supermoon on May 16 will bring darker nights for easier planet watching.

Overview

  • The tight formation, which peaked before sunrise Thursday, sat low over the eastern horizon and faded fast in the dawn glow.
  • Best views came about 45 minutes before sunrise, with all three objects under roughly 20 degrees high, so a clear, flat eastern horizon was key.
  • The Moon appeared as a very thin waning crescent at about 8% illumination, marking the final days before the new phase on May 16.
  • Experts urged viewers to avoid telescopes or binoculars near sunrise to prevent eye injury from an accidental look at the Sun.
  • The new moon will darken evening skies, setting up easier views as bright Venus moves closer to Jupiter for a close pairing in early June.
