A multi-spectrum view of our galaxy.
The Rings and Moons of Saturn
A time lapse taken from the front of the International Space Station as it orbits our planet at night. Beginning over the Pacific Ocean and continuing over North and South America before entering daylight near Antarctica.
Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Francisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, El Salvador, Lightning in the Pacific Ocean, Guatemala, Panama, Colombia, Ecuador, Peru, Chile, Lake Titicaca, and the Amazon. Also visible is the Earth’s ionosphere (thin yellow line), a satellite and the stars of our galaxy.

Artist’s concept of the four tails of the Sagittarius dwarf galaxy (orange clump on left of the image) orbiting the Milky Way. The bright yellow circle to the right of the Milky Way’s center is our sun (not to scale). We can see the Sagittarius galaxy’s star tails stretching across the sky.

Most Powerful Storms of the Solar System
NASA detects extreme temperatures on Saturn after an enormous storm
In December 2010, Saturn was quickly overrun by a storm several times the size of Earth. For months the atmospheric outburst raged, growing and traveling so quickly that it soon managed to wrap itself around the entire northern hemisphere. To date, it is the most massive storm we’ve ever observed on the ringed planet. Now, NASA scientists are saying the storm was even more powerful than previously believed — and that things got very, very hot.
Shortly after the Saturnian storm erupted in late 2010, NASA scientists used infrared imaging equipment onboard the Agency’s Cassini spacecraft to identify two “beacons” within the tempest, where temperatures were elevated above normal by around 20 degrees Kelvin. This temperature differential, explains planetary scientist Brigette Hesman, is regarded as “reasonable” for your typical Saturnian storm.
