These two great grey owls look like they're ready to play, which seems fitting on Super Bowl (or 'superb owl') Sunday. Great greys are bigger than most other owls, with broad wings and a long tail. But before you pencil them in at offensive line, consider that most of their size comes from feathers—they're relative lightweights. They generally live in pine and fir forests with meadows nearby, hunting small rodents at night and avoiding areas with people. Great greys hunt by listening and watching from a perch, then swooping down on their prey—sometimes plunging into more than a foot of snow to make a diving catch. Super Bowl LV will be played tonight at Raymond James Stadium in Tampa, Florida, with the Weeknd performing at halftime.

Chamonix is a winter sports resort town and one of the oldest ski resorts in France. As the highest European mountain west of Russia, Mont Blanc attracts mountain climbers. There is a cable car up to the 3,842 m (12,605 ft) Aiguille du Midi. Constructed in 1955, it was then the highest cable car in the world and remains the highest vertical ascent cable car in the world.

When the sky is clear, and the moon hangs low in the horizon, you can sometimes spot a halo around it, like the one captured in this image from Hug Point Falls on the Oregon coast. And sometimes within that halo, you may also see a bright spot that appears to be a second moon. No, it's not the moon's long-lost twin, but an optical phenomenon called a paraselene, more commonly referred to as a moon dog or mock moon. This 'false' moon can appear when the real moon is at least a quarter visible and is bright enough for its light to refract off hexagonal-plate-shaped ice crystals floating in the atmosphere. Moon dogs are more commonly seen in winter months, when the ice crystals are more prevalent in the clouds.
