2020 saw many exciting astronomical events from the great conjunction to meteor showers. Stargazers in 2021 can look forward to an even more impressive lineup of events from supermoons, lunar eclipses, meteor showers as well as a total solar eclipse.
While some of these events such as the full moon and the supermoon can be viewed from anywhere in the world, this year’s total solar eclipse can be seen only in Antarctica.
You may use the calendar to plan your trip to dark sky areas for better chances of viewing meteor showers.
