It's the 40th anniversary of Earth Day today. To honor our beloved planet, it's nice sometimes to stop and envy the view enjoyed by such a tiny slice of humanity: the astronauts. Here we've compiled some of our favorite views of Earth from space.
In addition to more conventional images taken from spacecraft and satellites, we've also included more data-rich visualizations of the sort that continue to help us understand our great planet.
Launch the gallery above for images of earthquakes, fires, sunsets, ice shelves and more. Happy Earth Day!
