What is a lunar eclipse? What is a solar eclipse? This short video explains the difference between these regularly occurring events that can be observed from Earth.

The video uses a mix of ground- and space-based imagery of eclipses, including footage from the International Space Station, ESA's Proba-2 satellite and the Japanese-led Hinode satellite. 
Remember: never look directly at the Sun, even when partially eclipsed, without proper eye protection such as special solar eclipse glasses, or you risk permanent eye damage.
