Watch the Exploratorium's live coverage of the lunar eclipse that occurred on January 20th, 2019.
A total lunar eclipse occurs when Earth comes between the Sun and the Moon and covers the Moon with its shadow. The eclipsed Moon sometimes appears to turn red, earning it the nickname of “Blood Moon.”
During the three-hour lunar eclipse, the Exploratorium attempted to broadcast a telescope view of the Moon live from Pier 15 on San Francisco’s Embarcadero but sadly the clouds blocked our view in San Francisco. Luckily, we are able to include the Griffith Observatory's amazing telescope feeds. We began just before the partial eclipse, continued through totality, and ended about 20 minutes before partial eclipse ended.
Along with the sight of Earth’s shadow moving across the Moon, you will experience live commentary from Exploratorium scientists. We also included a special audio track that was created a real-time and is a generative musical composition based on the features and geometry of a 3-D model of the Moon, which shifts and changes as the eclipse continues.
