Flames from the solid rocket boosters lit up the clouds of smoke and steam trailing behind shuttle Atlantis on May 19, 2000, as it lifted off on mission STS-101. It was the shuttle program’s third space station assembly flight, and first space flight for astronaut Jeff Williams, currently aboard the station as a member of the Expedition 47 crew. via NASA http://ift.tt/20aXPa5

Together with irregular galaxies, spiral galaxies make up approximately 60 percent of the galaxies in the local universe. However, despite their prevalence, each spiral galaxy is unique — like snowflakes, no two are alike. This is demonstrated by the striking face-on spiral galaxy NGC 6814. via NASA http://ift.tt/1TKk7dX

Shown in this Hubble Space Telescope image, NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. via NASA http://ift.tt/1rZSvvv

The rear wheels of the space shuttle orbiter Columbia touched down on Rogers dry lake at Edwards Air Force Base, NASA’s Armstrong Flight Research Center (then Dryden), California, to successfully complete a stay in space of more than two days. Astronauts John W. Young, STS-1 commander, and Robert L. Crippen, pilot, were aboard the vehicle. via NASA http://ift.tt/1TTGD8R

Astronomers have uncovered a near-record breaking supermassive black hole in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii, may indicate that these monster objects may be more common than once thought. via NASA http://ift.tt/1UWtvRX

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
