Kasanka National Park in Zambia, Africa, is home to an unlikely natural phenomenon — the world’s largest mammal migration. Each year, from October to December, millions of straw-colored fruit bats from across Africa converge on this evergreen swamp forest. These nocturnal mammals spend their nights feasting on wild fruits in the surrounding farmlands and their days resting in the forest. This cycle continues daily until January when the bats disperse and return to their respective habitats across the continent....

Nicknamed the "900-pound gorilla of meteor showers" by NASA, the Geminids outshine others with dust streams that are 5 to 500 times more massive. The "shooting stars" are also easier to spot because they travel through the skies at about 22 miles (35 km) per second. This is about half the speed of the Perseid meteors, which zip by at about 37 miles (60 km) per second every year in August....
