Defying its reputation as the gloomy planet, Saturn looks almost cheery as its southern hemisphere begins a 7-year-long summer, when temperatures will soar to a torrid −180 degrees Celsius. NASA's Planetary Photojournal provides a slew of snapshots showing the nine planets, along with local asteroids and comets. You can select from recent images by the Hubble Space Telescope and Cassini orbiter, for example, or classic portraits by the Voyager and Mariner spacecraft. Every picture carries an in-depth caption that clearly explains what you're seeing.

For down-to-earth imagery, visit this collection from the MISR project, which uses a bank of nine cameras mounted on the Terra satellite to monitor atmospheric and surface conditions on our planet. The site regularly posts timely shots of earthly events, such as dust streaming down the canyons of Southern California, driven by the Santa Ana winds, or smoke clouds from the ferocious fires that encircled Sydney, Australia, last December.
