Journey into space with the astonishing images from NASA's Hubble and James Webb Space Telescopes. Since 1990, Hubble has recorded more than a million observations, making it one of the most productive scientific instruments ever built-and Webb, deployed in 2022, promises to reveal even more of the known universe, thanks to its infrared vision. Together, these telescopes probe the cosmos, peering deep into time and allowing greater understanding of what lies beyond our atmosphere. Discover new horizons with the 12 images in this calendar, each accompanied by a description of the celestial phenomenon depicted. Important dates in the history of space exploration, as well as this year's eclipses and major meteor showers, are noted throughout.
