Many people who stayed up last night may have been lucky enough to witness the blood moon of the spectacular full lunar eclipse. During the moment of maximum totality the moon turned a deep rusty red, but do you know what caused that colour?

To answer this you need to take a flight of the imagination... If you were an astronaut on the moon during the full eclipse in that moment you'd see Earth ringed with the red of all the sunsets and sunrises happening all around the planet. The Earth’s atmosphere bends that light and it falls across the moon... Our astronaut would see the moon’s surface bathed in ruby light. Now isn’t that a magical thought!

Maybe one day when we rediscover our pioneering spirit for human exploration and we will have a permanently crewed based on the moon, and someone will witness this for themselves. And maybe, just maybe it might be one of our children.
