Upload your astronomy photos to identify stars and objects in the sky. Get accurate coordinates and detailed info for any astronomical image.
Identify stars in your astronomy photos
Astrometry.net is a handy tool for anyone with photos of the night sky who wants to know exactly what's in their images. You can upload an astronomical image—whether you know the coordinates or not—and the site will analyze it to pinpoint the exact celestial coordinates, calibrate the image, and list known objects in the field of view.
This makes it especially useful for amateur astronomers, educators, and researchers who want to learn more about their sky images or verify their observations. You don't need to be an expert; just provide your photo and get back reliable information and helpful metadata.
Whether you're cataloging your observations, sharing discoveries with friends, or just curious about what you captured, Astrometry.net makes it easy to identify stars, galaxies, and other celestial objects in your photos.
