Thousands turned to the sky to witness a lunar eclipse as a blood moon rose over Victoria last Tuesday night. Lunar eclipses occur when the sun, Earth and moon all line up, with Earth casting a shadow across the moon. A blood moon is so called from the red hue of the moon at totality, but the hue the moon appears would depend on local atmospheric conditions: If there’s enough pollution, volcanic dust or cloud cover, the moon can appear quite red. We were lucky enough not to have cloud cover and the moon appeared quite red! Australians will not get to see another lunar eclipse until 2025.
