Pressure is on to find the cause for vision changes in space
The human body is approximately 60 percent fluids. During spaceflight, these fluids shift to the upper body and move across blood vessel and cell membranes differently than they normally do on Earth. One of the goals of the Fluid Shifts investigation, launching to the International Space Station this spring, is to test the relationship between those fluid shifts and a pattern NASA calls visual impairment and intracranial pressure syndrome, or VIIP. It involves changes in vision and the structure of the eyes and indirect signs of increased pressure in the brain, and investigators say more than half of American astronauts have experienced it during long spaceflights.

Cloudy, with a wisp of liquid rock: Clouds around exoplanets analyzed
Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system, thanks to new research.

New data on the nature of dark matter
Recent research contributes to the effort to determine the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.

Vanishing Binary Star Calibrates Space-Time Warp | Animation
Two stars, each more massive than our Sun but orbiting 100 times closer, affect each others gravity wells allowing astronomers to gauge space-time itself., Tue, 03 Mar 2015 18:30:48 GMT

LEGO 'Star Wars' Show Heading to Disney: Report
"Star Wars" is about to get the LEGO treatment. Disney XD is planning to air "LEGO Star Wars: Droid Tales" later in 2015, according to a report from the Hollywood Reporter. The five-episode series will act as a re-telling of the six "Star Wars" films from, Tue, 03 Mar 2015 18:30:48 GMT

Mars on Earth: Mock Space Mission Examines Trials of Daily Life
Put six people into an isolated environment for months at a time, and lots of things can happen: frustration, conflict, or at best ? a tight-knit group of people working happily for a common goal., Tue, 03 Mar 2015 18:30:48 GMT

Far from home: Wayward cluster is both tiny and distant
Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's "suburbs." It is located where astronomers have never spotted such a small cluster of stars before.

Why don't we search for different life?
If we really want to find life on other worlds, why do we keep looking for life based on carbon and water? Why don't we look for the stuff that's really different? Astronomy & Space News, Tue, 03 Mar 2015 18:30:48 GMT

OSIRIS catches glimpse of Rosetta's shadow
Several days after Rosetta's close flyby of comet 67P/Churyumov-Gerasimenko on 14 February 2015, images taken on this day by OSIRIS, the scientific imaging system on board, have now been downlinked to Earth. With a resolution of 11 centimeters per pixel, these data from OSIRIS' Narrow Angle Camera reveal highly detailed structures on the comet's surface. Since at closest approach Sun, spacecraft and comet were almost perfectly aligned, few shadows are visible in the images. With one exception: as a side-effect of this exceptional observational geometry Rosetta's shadow on the surface can be seen surrounded by a bright halo-like region.

Fierce 'superflares' from the sun zapped an infant Earth
Our young sun may have routinely blasted Earth with gobs of energy more powerful than any similar bombardments recorded in human history. Astronomy & Space News, Tue, 03 Mar 2015 18:30:48 GMT
