The Oceans Melting Greenland (OMG) field campaign team is flying NASA’s G-III aircraft at about 40,000 feet. On a clear day, this altitude also provides a stunning perspective of one of the world’s two great ice sheets (the other is Antarctica). The flight Saturday, March 26, over the northeast coastline was one of those clear days. via NASA http://ift.tt/1RF6bE2

The turbulent atmosphere of a hot, gaseous planet known as HD 80606b is shown in this simulation based on data from NASA’s Spitzer Space Telescope.Spitzer measured the whole heating cycle of this planet, determining its coolest (less than 400 degrees Fahrenheit) and hottest (2,000 degrees Fahrenheit) temperatures. via NASA http://ift.tt/22HDjDz

A new map of Mars’ gravity is the most detailed to date, providing a revealing glimpse into the planet’s hidden interior. The map was derived using Doppler and range tracking data collected by NASA’s Deep Space Network from three NASA spacecraft in orbit around Mars: Mars Global Surveyor, Mars Odyssey, and the Mars Reconnaissance Orbiter. via NASA http://ift.tt/1S0UaX5
