Types of Moons
- Blood Moon: A total lunar eclipse where Earth’s atmosphere scatters blue light and lets red light reach the Moon, giving it a reddish colour. It occurs only during a total lunar eclipse.
- Blue Moon: The second full moon in a calendar month (modern definition), which happens about once every 2–3 years. It has no colour change.
- Black Moon: An event where a calendar month has no full moon, or the 2nd new moon in a month.
- New Moon: The Moon lies between Earth and the Sun, making it invisible from Earth.
