The space agency shared a new video showcasing its 2023 achievements, ranging from its first asteroid sample return project to its outline of how to send humans to Mars — and beyond.

The night sky of 2023 delivered many amazing views of the moon, comets, meteors and even space debris. Here are this year’s most memorable skywatching sights.

The "forbidden" light of the spiral galaxy MCG-01-24-014 is captured in a new image from the Hubble Space Telescope, suggesting the galaxy contradicts common rules of quantum physics.

The Hubble Space Telescope photographed NGC 2814, an irregular galaxy that belongs to a group of four "late-type galaxies" collectively called Holmberg 124.
