On Sunday night, Match 22, the strange planet Uranus will float to the left of the crescent Moon. Here’s where the fun begins. Uranus is green because its atmosphere has lots of methane, which absorbs the sun’s red light but reflects the green and blue to our eyes.Grab those binoculars you haven’t used in years and sweep them leftward of the Moon until you see a little green star.
