CITIZEN SCIENTISTS DISCOVER GREEN GHOSTS: Citizen scientists have discovered a new form of upper atmospheric lightning: The Green Ghost. Catalogued for the first time only a year ago, Green Ghosts appear above strong sprites, leaving a weird verdant afterglow at the edge of space. A fine specimen was just photographed over New Mexico.
