Perhaps well known, but if you're looking for amazing wall art, the NASA Exoplanet series is fantastic

This is a poster series in a retro style. They look fantastic in large prints. The space telescope series is also on the page. I personally adore the JWST poster and have a large print of it in canvas form: https://exoplanets.nasa.gov/resources/2294/james-webb-space-telescope-poster/?layout=magic_shell&travel_bureau=true&cid=4,travel_bureau_missions
