Earth’s atmosphere bends and splits sunlight, creating rainbows and other displays, including the rarely seen “green flash.” Under clear, clean skies it appears with the first burst of sunlight before sunrise or the last glimpse at sunset.
Weekly Stargazing Tips
Unless otherwise specified, viewing times are local time regardless of time zone, and are good for the entire Lower 48 states (and, generally, for Alaska and Hawaii). Check out last week's tips if you missed a night.
Moon and Regulus
The Moon is in view most of the night tonight. Regulus, the brightest star of Leo, is close to its lower left as night falls, and stays close throughout the night.
Mercury in the Morning
The little planet Mercury just peeks into view over the next few days. Although it is quite bright, it’s also quite low in the east at first light, making it tough to find. In fact, from high northern latitudes it might not be visible at all.
The Moon will be full at mid-day tomorrow as it passes directly opposite the Sun in our sky. The full Moon of March is known as the Sap Moon, Worm Moon, or Lenten Moon.
Old Mars Rock
Mars is putting in a good showing right now. The planet rises in late evening and shines like a bright orange star. It will get even brighter over the coming weeks as Earth moves closer to it.
Moon and Companions
Spica, the brightest star of Virgo, stands almost directly below the Moon as they rise in late evening. The bright orange planet Mars is close to the left of Spica.
More Moon and Companions
A tight, bright triangle scoots across the south late tonight: the Moon, the planet Mars, and the star Spica. They climb into good view in late evening, with Mars and Spica like ears above the Moon — Mars to the left, Spica to the right.
