Listening for Milky Way Pulsars
"The center of our Milky Way galaxy, in the middle of the southern hemisphere winter riding high in the sky over the CSIRO Parkes Radio Telescope (‘The Dish’) ‘observing’ Milky Way pulsars." - Phil Hart

"NGC 346 is a nebulous cluster about 210k light years distant on the edge of the Small Magellanic Cloud in the constellation Tucana. NGC 346 is often described as a stellar nursery and in this image, one can see stars being born in the caldera of a stellar volcano." - Colin Eldridge
Atlantis shuttle experience simulates outer space for NASA
Simulating outer space, the Atlantis shuttle experience is boldly going where no other has gone before,suspending an orbiter 30 feet in the air to display it in full flight mode. dedicated to NASA’s space shuttle program, the $100 million exhibit uses tunable lighting techniques to celebrate a technological marvel – as it would have appeared in action. installed in the 90,000 square feet museum at The Kennedy Space Center, american architects Pgav Destinations in collaboration with design firm Fisher Marantz stone used over 250 LED fixtures from Lumenpulse to create the dynamic scheme. the fixtures can be varied in color temperature and hue to recreate the unusual lighting conditions in space, and make it seem as if sunlight is reflecting off the orbiter.
Many black holes in stellar systems are surely surrounded by disks of gas and plasma gravitationally pulled from a close binary star companion. Some of this material ends up being expelled from the star system in powerful jets emanating from the poles of the spinning black hole.
How fast are you moving when you’re sitting still?

These images, taken with NASA’s Galaxy Evolution Explorer and the Pan-STARRS1 telescope in Hawaii, show a brightening inside a galaxy caused by a flare from its nucleus. The arrow in each image points to the galaxy. The flare is a signature of the galaxy’s central black hole shredding a star that wandered too close.
The computer-simulated gif animation shows gas from a tidally shredded star falling into a black hole. Some of the gas also is being ejected at high speeds into space. Astronomers observed the flare in ultraviolet light using NASA’s Galaxy Evolution Explorer, and in optical light using the Pan-STARRS1 telescope. The light comes from gas falling into the black hole, and glowing helium from the star’s helium-rich gas expelled from the system.
