"On Sat., Aug. 27, 2011, International Space Station Astronaut Ron Garan pointed an HD camera out a window of the Cupola to film one of the sixteen sunrises astronauts see each day. This sunrise image shows the rising sun as the International Space Station flew along a path between Rio de Janeiro, Brazil and Buenos Aires, Argentina."

Probably, this sunrise image is showing us an appearance of mesosphere among Earth atmospheric layer.
Amazing picture! It's curious if we can capture the moment of diffraction phenomenon through the sunrise at Space.
