Expedition 48 Commander Jeff Williams of NASA captured photographs of western Cuba and the Gulf of Batabanó as the International Space Station flew overhead. Williams shared this composite image on social media, writing, "Wow! Look at how the navy blue contrasts with the aqua, Gulf of Batabano Cuba." (More at NASA Picture of The Day)
 
Hubble Spots a Secluded Starburst Galaxy

hubble_friday_07152016.jpg


This image, taken by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys (ACS), shows a starburst galaxy named MCG+07-33-027. This galaxy lies some 300 million light-years away from us, and is currently experiencing an extraordinarily high rate of star formation — a starburst. (More at NASA Picture of The Day)
 
Melt Water Over Arctic Sea Ice

Sea ice across the Arctic Ocean is shrinking to below-average levels this summer. NASA’s Operation IceBridge, an airborne survey of polar ice, just completed its first flights studying the aquamarine pools of melt water on the ice surface that may be accelerating the overall sea ice retreat.

On July 20, 1976, at 8:12 a.m. EDT, NASA received the signal that the Viking Lander 1 successfully reached the Martian surface. This major milestone represented the first time the United States successfully landed a vehicle on the surface of Mars, collecting an overwhelming amount of data that would soon be used in future NASA missions.

The NASA Extreme Environment Mission Operations (NEEMO) 21 mission began on July 21, 2016, as an international crew of aquanauts splashed down to the undersea Aquarius Reef Base, 62 feet below the surface of the Atlantic Ocean. The NEEMO 21 crew will perform research both inside and outside the habitat during a 16-day simulated space mission. (More at NASA Picture of The Day)
 
Hubble Views a Galaxy Fit to Burst

This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy — a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.

Field Testing NASA's New Carbon-Dioxide Measuring Instrument

dsc_1488_sciflt_south_of_elko.jpg


A team of NASA scientists and engineers is poised to realize a lifetime goal: building an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. Developers of the CO2 Sounder Lidar instrument snapped this photo during a field campaign over California and Nevada. (More at NASA Picture of The Day)
