No need for a telescope! Here are a couple fun astronomical tidbits for April.

Watch for a Supermoon!

In April 2021, the full Moon arrives on the night of Monday, April 26. It will be its brightest and fullest at 11:33 P.M. Eastern Time.

This full Moon is extra special because it will also be a supermoon! This means that it will be just a tiny bit bigger and brighter than the usual full Moon, though it’s difficult to tell just by looking at it. To really tell the difference between a supermoon and a regular full Moon, you would need to see them side by side in the sky!

For the best view of this full Moon, which is traditionally called the Pink Moon, venture outside with a parent on Monday the 26th. Read more about the Full Pink Moon here!

Find the Date of Easter with Astronomy

Did you know that the date of Easter depends on the full Moon and the spring equinox? 

That’s right! Easter’s date, which is different every year, is determined by the dates of the spring equinox and the full Moon. The holiday is celebrated on the first Sunday after the first full Moon of the spring season. This full Moon is called the “Paschal full Moon.”

Can you calculate Easter’s Date in 2021?
