Chris Hadfield on the International Space Station
Chris Hadfield, commander on the International Space Station, has been capturing the attention of the followers of social media recently. Besides interactions with former Star Trek cast members, he has been posting some amazing pictures. Here are some of my favourites (mostly earth science related).
Noctilucent clouds. They form at high latitudes, at altitudes in excess of 75 km. They are rarely visible from the ground.
Winnipeg, the capital city of my home province of Manitoba. South is towards the left of this picture. The large linear structure on the bottom of the image is the Floodway, a large diversion channel that spares the city from catastrophic floods.
Mt Vesuvius. Pretty amazing that there are settlements encircling the entire volcano, considering it is still active.
