The final frontier is an unendingly beautiful expanse filled with unimaginable wonders, making it the perfect sandbox for photographers, astronomical observatories and space-based telescopes to capture incredible images that we can hardly fathom. And 2025 was no different.

This year, we covered a range of stunning space images, from an eye-catching alien comet and a planetary parade portrait to the first Vera C. Rubin photos and otherworldly animal lookalikes. Here are 10 of our absolute favorites.
