Mimas and Pandora

07/29/2013 08:00 PM EDT
The Saturn moons Mimas and Pandora remind us of how different they are when they appear together, as in this image taken by NASA’s Cassini spacecraft. Pandora’s small size means that it lacks sufficient gravity to pull itself into a round shape like its larger sibling, Mimas. Researchers believe that the elongated shape of Pandora (50 miles, or 81 kilometers across) may hold clues to how it and other moons near Saturn’s rings formed. This view looks toward the anti-Saturn hemisphere of Mimas (246 miles, or 396 kilometers across). North on Mimas is up and rotated 28 degrees to the right. The image was taken in blue light with Cassini’s narrow-angle camera on May 14, 2013. The view was acquired at a distance of approximately 690,000 miles (1.1 million kilometers) from Mimas. Image scale is 4 miles (7 kilometers) per pixel. Pandora was at a distance of 731,000 miles (1.2 million kilometers) when this image was taken. Image scale on Pandora is 4 miles (7 kilometers) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Google Time-lapse offers view of Earth over 3 decades

(05/10/2013) Google has released a series of time-lapse images showing global change between 1984 and 2012. The images are sourced from NASA’s Landsat mission, a series of Earth-observation satellites that have orbited the planet since 1972, providing scientists, policymakers, and the general public with a wealth of data and imagery used for a wide range of applications.

Weird Underwater Waves Spotted from Space off the coast of Trinidad

Repeating Islands

trinidad-waves-nasa-EO

In the ocean, there are more waves than meet the eye, Douglas Main reports for ouramazingplanet.com.

Below the whitecaps breaking on the sea surface, so-called internal waves ripple through the water. These waves can travel long distances, but rarely does evidence of their existence surface — unless you’re looking down from space, that is.

This photograph, taken on Jan. 18 by a crewmember on the International Space Station, shows internal waves north of the Caribbean island of Trinidad, as featured by NASA’s Earth Observatory. From space, the appearance of the waves is enhanced due to reflected sunlight, or sunglint, aimed back at the space station, making the waves visible to an astronaut’s camera.

The most prominent waves can be seen in the upper left of the photograph, moving in from the northwest due to tidal flow toward Trinidad, according to the Earth Observatory. Another set can be seen moving…
