In March, observers in Chile were treated to an especially spectacular sight, as the night sky lit up with orange and green hues. To top it off, the moon was in a full lunar eclipse.
What is it?
Where is it?
Both telescopes are located 310 miles (500 km) north of Santiago, Chile, at an altitude of 7,200 feet (2,200 meters).
Why is it amazing?
Lunar eclipses are captivating to watch, as Earth passes directly between the sun and the moon, casting its shadow onto the surface of the moon. This only happens when the Earth, sun and moon are all perfectly aligned. According to NOIRLab, this alignment period was used by ancient astronomers as early as 600 BCE and called a "saros." The time between saros periods is around 18 years, 11 days, and 8 hours.
