Sarychev Peak is located on Matua Island in the Kuril Islands of Russia. When the volcano erupted on June 11, 2009, the expulsion of debris caused significant interruption to air traffic between east Asia and North America. The eruption was also so great that astronauts aboard the International Space Station were able to photograph the plumes of ash and smoke rising from its cone, as the force of its shock waves dispersed all clouds covering the area.

Exactly 50 years ago today — on December 21, 1968 — NASA launched the Apollo 8 spacecraft, which sent the first humans out of low Earth orbit and around the moon.

This photograph speaks to our mission here at Daily Overview; to give everyone a chance to appreciate our home in its entirety and reflect on its beauty and fragility all at once.
