Hubble Views a Galaxy Fit to Burst

NASA: Image of the Day -

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.

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.

Melt Water Over Arctic Sea Ice

NASA: Image of the Day -

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.

Hubble Spots a Secluded Starburst Galaxy

NASA: Image of the Day -

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.

Western Cuba and Gulf of Batabanó

NASA: Image of the Day -

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."
