“Lewin's Challenge: 360 Degree Star Trails” is copyrighted by Peter Wienerroither (U. Wien). NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThis image from Vienna, Austria, shows 360-degree star trails, a digital trick. Real star trails from Earth's spin cannot complete a full circle in a single exposure because the sun would rise. The Earth's rotation makes the sky appear to rotate around us, creating these trails.
