The Royal Observatory in Greenwich, England is currently exhibiting the shortlisted entries for the Astronomy Photographer of the Year competition. This amazing picture of the Milky Way and orographic lenticular clouds hanging above Liberty Cap, a granite dome in Yosemite National Park, was taken by Rogelio Bernal Andreo.
Summertime vacation timelapse tour of Yosemite National Park. For the first half you can watch shadows of clouds dance over the mountains and forests, and in the second half the night and the Milky Way surround a campsite.
Just sit back for a few seconds and gawk at this time lapse video from Yosemite National Park. Really cool lenticular clouds, the moving Milky Way, planes darting across the sky, and cars darting across the landscape.
