Early one February morning in 2013, a bright meteor and several flashes were seen near the Ural Mountains in western Russia. The 20-meter-diameter (65 ft) meteoroid broke apart in the atmosphere, releasing most of its energy about 20 to 40 kilometers (12 to 25 miles) up. A few days later, geologists collected 450 small fragments averaging 3 to 6 centimeters wide from an area 40 kilometers (25 miles) south of Chelyabinsk. They added up to 4 kilograms (9 lbs) of meteorites.

A new calculation of Saturn’s rotation period cuts its day down by a few minutes. A single day on the sixth planet from the sun lasts 10 hours, 32 minutes, 45 seconds (plus or minus 46 seconds). The findings were published in Nature this week.
