Hubble Peers Into the Heart of the Milky Way Galaxy

Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy. via NASA http://ift.tt/1VVmCzh

Earth Art in Northwestern Australia

During an International Space Station flyover of Australia, NASA astronaut Jeff Williams captured a colorful image of the coast and shared it with his social media followers on March 29, 2016, writing, "The unique terrain of the northwestern Australian coast." via NASA http://ift.tt/1q2mrGx

Greenland's Ice Sheet From 40,000 Feet

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

Simulated Atmosphere of a Hot Gas Giant

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

Map of Mars Gravity

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

Haze Layers Above Pluto

This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. via NASA http://ift.tt/1MpKPpM

March 16, 1966: Gemini's First Docking of Two Spacecraft in Earth Orbit

On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit. This crucial spaceflight technology milestone would prove vital to the success of future moon landing missions. via NASA http://ift.tt/1VcGwFr

South Africa From the Space Station's EarthKAM

The remotely controlled Sally Ride EarthKAM aboard the International Space Station snapped this striking photograph of South Africa on Feb. 9, 2016. The EarthKAM program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the space station when it passes over those features. via NASA http://ift.tt/1RLHIu8
