December 21 is always a notable day – the winter solstice is a time when many celebrate a new season and the shortest day of the year (it’s all uphill from there, for those of us who like daylight!). This year, though, stargazers and astronomers are counting down the days until the 21st for a different reason. For the first time in eight centuries, the Christmas Star will appear in the sky!

On December 21, Delawareans will be able to see a rare sight when the “Christmas Star” appears over Delaware in the night sky.

When Jupiter and Saturn align, you’ll be able to see a remarkably bright spot in the sky!

You won’t need a telescope to see the Christmas Star, but if you’ve got one, you’ll get an amazing view.

If you’ve ever wondered why those who celebrate Christmas top their trees with a star, well, now you know!

Head to the beaches or the bay to see it under some of the darkest skies in Delaware.

To find the darkest skies in Delaware, use the Dark Site Finder map. Sussex County’s beaches tend to be particularly bright, and Brandywine Creek State Park’s Hawk Watch Parking Lot is a great place to stargaze.
