thinking of Earth as ‘the blue planet’ has been a popular myth, particularly since we saw the first snap shots the astronauts took from orbit and the moon
but from farther away, ‘pale blue dot’-distance and beyond, planets like Earth actually look red because biological molecules such as oxygen, water, carbon dioxide and methane show up in the red wavelengths
so if E.T. is looking for us, she’s not likely to be paying attention to blue dots
more next time
Blessed Be
