Deployment of the Space Station’s Roll Out Solar Array Experiment Over the weekend of June 17-18, engineers on the ground remotely operated the International Space Station’s Canadarm2 to extract the Roll Out Solar Array experiment from the SpaceX Dragon resupply ship. The experiment will remain attached to the Canadarm2 over seven days to test this advanced, flexible array that rolls out like a tape measure. via NASA http://ift.tt/2tp28oW

Webb Telescope Set for Testing in Space Simulation Chamber NASA’s James Webb Space Telescope sits in front of the door to Chamber A, a giant thermal vacuum chamber located at NASA’s Johnson Space Center. The telescope will soon be moved into the chamber, where it will spend a hot Houston summer undergoing tests at sub-freezing cryogenic temperatures. via NASA http://ift.tt/2sKRZWE

Jupiter’s Clouds of Many Colors NASA’s Juno spacecraft was racing away from Jupiter following its seventh close pass of the planet when JunoCam snapped this image on May 19, 2017, from about 29,100 miles (46,900 kilometers) above the cloud tops. via NASA http://ift.tt/2s9872E

Celebrating Flag Day NASA astronaut Jack Fischer took this photograph of an American flag in one of the windows of the International Space Station’s cupola, a dome-shaped module through which operations on the outside of the station can be observed and guided. Throughout NASA’s history, spacecraft and launch vehicles have always been decorated with flags. via NASA http://ift.tt/2rsJ3EW

Illustration of Cool Dust Around an Active Black Hole This artist illustration shows the thick ring of dust that can obscure the energetic processes that occur near the supermassive black hole of an active galactic nuclei. Researchers have found that the dust surrounding active, ravenous black holes is much more compact than previously thought. via NASA http://ift.tt/2sxGp0k

Turquoise Swirls in the Black Sea On May 29, 2017, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured the data for this image of an ongoing phytoplankton bloom in the Black Sea. The image is a mosaic, composed from multiple satellite passes over the region. via NASA http://ift.tt/2sl9b4F

Watching a Volatile Stellar Relationship In biology, “symbiosis” refers to two organisms that live close to and interact with one another. Astronomers have long studied a class of stars – called symbiotic stars – that co-exist in a similar way. Astronomers are gaining a better understanding of how volatile this close stellar relationship can be. via NASA http://ift.tt/2rI8dMJ
