As a teenager at boarding school, Tom Sever, later a NASA archaeologist at the John C. Stennis Space Centre in Mississippi, began sneaking outdoors after lights out. 'I fell in love with the sky and started inventing my own constellations,' he says. Two of his night-sky creations: a 1957 Chevy convertable and a railroad boxcar.
'I know the constellations, and I've even taught them,' says Sever. 'But even today, the most vivid ones in the sky are the ones I first created.'
