This Is What the Moon Looks Like From Space

"On Sunday, July 31, 2011, when Expedition 28 astronaut Ron Garan aboard the International Space Station looked out his window, this is what he saw: the moon. And, he saw it 16 times. Said Garan, "We had simultaneous sunsets and moonsets." For Garan and the rest of the station crew, this extraordinary event is a daily occurrence. Since the station orbits the Earth every 90 minutes, each day the crew experiences this about 16 times a day."

Tuesday's coronal mass ejection spewed tons of gas and radioactive material into space in the general direction of Earth. (You can watch a video of it here.) The solar material is expected to reach Earth sometime Friday, when it may trigger spectacular polar light shows, said Dr. Tony Phillips of Spaceweather.com. Ejections of this size can also cause minor radio interruptions in polar regions, according to the site.
