Lucianne Walkowicz: Look up for a change (TED TALK)

“Lucianne Walkowicz asks: How often do you see the true beauty of the night sky? At TEDxPhoenix, she shows how light pollution is ruining the extraordinary — and often ignored — experience of seeing directly into space. Lucianne Walkowicz works on NASA’s Kepler mission, studying starspots and “the tempestuous tantrums of stellar flares.” Several research projects developed by the NASA proves how urgent is the problem of the environmental issue of the polluted air.
