Astronomy Picture of the Day (or APOD) has just released new 2015 calendars filed with magnificent photos of the Earth and space. Currently there are eight calendars total – Galaxies, General, Skyscapes, Moons & Planets, Star Clusters, Spaceflight, Sun, and Weather & Volcanoes. The calendars can be downloaded for free from Friends of APOD's website though they accept donations for anyone willing to pitch in. Printed copies are now available for a fee, as well.
The best calendar, in our opinion, is Weather & Volcanoes. Here you'll find everything from beautiful iridescent clouds photographed in 2009 from the Himalayan Mountains in Nepal, behind the 6,600-meter peak named Thamserku, to lightning bolts illuminating the ash pouring out of the Eyjafjallajkull volcano. Each photo is a reminder of the amazing power and beauty of Mother Nature and the world in which we live in.
