We’ll get a lunar eclipse this Tuesday morning, and it’s generating a lot of buzz, especially since such eclipses have been dramatically called Blood Moons in recent years. That’s because the Moon turns reddish when the eclipse is total. In truth it’s actually a coppery hue, which isn’t really the color of blood unless there’s something very wrong with your hemoglobin.

The winter solstice occurs on Sunday, December 21, around nightfall, when Earth’s south pole tilts most directly toward the Sun, giving the Northern Hemisphere its shortest day of the year; starting Monday, daylight increases slightly and the Sun climbs higher, bringing a hint of added warmth. The Sun rises and sets at its most extreme points along the horizon, and although often labeled the start of winter, that date is a human convention rather than a physical change. Astronomically, the solstice features the Sun’s most curved, rainbow-like path across the sky, reaching its lowest noon height of the year and producing the longest shadows.
