2020 Sky Almanac

Newly Revised!

This year offers up some beautiful skywatching treats, including the opposition of Mars and the closest conjunction between Jupiter and Saturn in four centuries. You can find all the details on these and many other events in our 2020 Sky Almanac. The digital version of the Almanac was revised on July 1 with additional skywatching information and the latest details on upcoming milestones in space exploration! Plan your skywatching adventures with tips on eclipses, meteor showers, and more, plus keep an eye on the naked-eye planets. And we tell you about the rights and wrongs of astronomy and space exploration in science fiction with essays on everything from spinning space stations to the search for extraterrestrial life.
