2023 Space-Telescope Advent Calendar

Once again, it’s time for one of my favorite holiday traditions: the 16th annual Space-Telescope Advent Calendar, featuring images from both NASA’s Hubble telescope and its new James Webb Space Telescope. Every day until Monday, December 25, this page will present a new, incredible image of our universe from one of these two telescopes. Be sure to come back every day until Christmas, and follow us on social media for daily updates. I hope you enjoy these amazing and awe-inspiring images, as well as the continued efforts of the science teams that have brought them to Earth. I say this every year, but it really is a joy to put this calendar together each December.

Wishing you all a merry Christmas, happy holidays, and peace on Earth.
