APOD Explorer

Every day, NASA's official astronomy picture or video. Browse 30 years of archive, save favorites, and get on-device AI readings tailored to you.

Every day, NASA publishes a new astronomy picture or video, with an explanation written by a professional astronomer. APOD Explorer brings it to you with an experience built for exploring the universe, not just looking at it.

THE FULL ARCHIVE SINCE 1995 Over 11,000 photos and videos, from the very first APOD to today. Full-text search across titles and explanations, curated tag collections (galaxies, nebulae, eclipses, Earth from space, and many more), and an "On This Day" section showing what was published on this date across the years.

READINGS TAILORED TO YOU, ON DEVICE With Apple Intelligence, every explanation can be generated at different reading levels: quick, general, for kids, or for experts. NASA's original explanation can also be translated right on your device — nothing is sent to any server.

FAVORITES THAT SYNC Save the photos you love and access them from any of your devices through iCloud. No one else can see them.

WIDGETS AND LOCK SCREEN Two widgets — "Picture of the Day" and "Today's Sky" — that refresh themselves every morning, on the Lock Screen too.

SHARE WHAT YOU DISCOVER Share the photo or, when the day's APOD is a video, a poster generated from it, straight from the detail view or from the widgets extension.

NO ACCOUNTS, NO ADS, NO TRACKING APOD Explorer doesn't require sign-up and doesn't show ads. If you enjoy the app, you can leave a voluntary tip from Settings — a gesture of support that never unlocks features.

A daily window into the universe, with NASA's complete archive always in your pocket.
