The sky on
your birthday.
“Red Nebula, Green Comet, Blue Stars” is copyrighted by Tom Masterson. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteThis colorful skyscape was captured following Comet Wirtanen's closest approach to Earth. The comet's green coma is brought out by digital exposures, registered on its position below the Pleiades star cluster. These exposures also reveal blue starlight reflected by dust clouds surrounding the young Pleiades stars. The comet was just visible to the eye.
