Channel: Introduction to Astronomy
Date: 22/04/2024

In today's image, we see a thin waning crescent moon in the sky over Mt. Etna. We also see smoke rings from the volcano - this is a rare effect that occurs only when conditions in both the volcano and the atmosphere are just right.

The Women in Astronomy video will be uploaded each Wednesday.
The Exploration of the Solar System video will be uploaded each Friday.
