Question

Quizplus · Accepted Answer

The first rings of Uranus were discovered from Earth in 1977 when astronomers observed the planet passing in front of a distant star. As Uranus moved in front of the star, the star's light flickered, indicating the presence of rings that were blocking the light momentarily. This method of observation, known as stellar occultation, allowed for the discovery of the rings without direct imaging from space probes or telescopes.
