A Warm-Blooded Fish, Thunderstorms From Space, And Other Amazing Images Of The Week

Plus, the skeleton of the man who brought leprosy to Britain
Astronaut Terry Virts, the commander of NASA's current expedition at the International Space Station, tweeted this picture of shadows cast by thunderstorms, calling the picture #EarthArt. This isn't the only media he's posted--Virts has also posted Vines of a massive lightning storm over India and Super Typhoon Noul as it approached the Philippines. But he doesn't just document Earth happenings--he's also posted photos of space experiments at the ISS, mealtimes with floating food, and haircuts in space. Virts and his crew have spent the last few months conducting astrophysics research, physical science investigations and technology demonstrations. Terry Virts via Twitter
