On April 22 was Earth Day, since 1970 it's been a day set aside to remember and appreciate the Earth's environment, and all of our roles within it. As a way to help appreciate and observe our environment, I've collected 39 recent images here, each a glimpse into some aspect of the world around us, how it affects and sustains us, and how we affect it. Here's hoping everyone had a great Earth Day.
The most detailed true-color image of the entire Earth created to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer of our planet. Much of the information contained in this image came from a single remote-sensing device-NASA's Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite.

A gray whale surfaces near the mouth of the Duwamish River late Saturday March 27, 2010 in Seattle, Washington. The nearly 40 foot-long animal was watched by excited spectators as it hugged the shore around the West Seattle peninsula earlier in the day. Gray whales are not as common in Puget Sound as orca whales; gray whales are rarely seen in Elliott Bay near downtown Seattle. Maritime officials with the Port of Seattle were concerned the whale would attempt to travel up the Duwamish River, a major industrial area and Superfund site.

The Sun appears slightly squished in this image of the Earth eclipsing the Sun seen from NASA's recently-launched Solar Dynamics Observatory in high orbit. An instrument on board, the Helioseismic and Magnetic Imager, was undergoing a series of adjustments when its view was partially blocked by the Earth. At the edges of the shadow, the Sun's shape bends, due to the light's refraction by the Earth's atmosphere.
