About StellarSnap
StellarSnap is an astronomy and space-education website that helps curious readers explore the universe through imagery, interactive tools, and accessible explanations. Its daily feature presents NASA’s Astronomy Picture of the Day, with accompanying descriptions and image credits, while a browsable archive lets visitors revisit astronomy pictures dating back to 1995. The site also offers recent picture highlights and links to the full NASA APOD story.
Visitors can learn by experimenting with StellarSnap’s interactive simulators. The Orbit Simulator lets users explore satellite motion around Earth or other planets by adjusting altitude, velocity, and eccentricity. The Time Dilation tool compares how time passes near different objects, including planets, neutron stars, and black holes. A plain-language astronomy glossary defines terms found in image captions and connects them with relevant pictures. Longer articles cover topics such as black holes, redshift, and gravitational lensing.
StellarSnap also offers optional email updates about new tools, features, and articles, with no daily messages. The site states that it is not affiliated with or endorsed by NASA.
