NASA says Roundworms to be used to study Microgravity effects on the Human Body

 

Written by Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Humans have long been fascinated by the cosmos. Ancient cave paintings show that we’ve been thinking about space for much of the history of our species.  The popularity of recent sci-fi movies suggest that the human mind just might be coming to grips with the harsh environment “out there.”

The human body is another matter.

When gravity is greatly reduced—as in spaceflight—we no longer use our muscles to resist the usual pull of a planetary mass, and, without additional exercise astronauts lose both bone and muscle.

NASA’s Wide-field Infrared Survey Explorer (WISE) data used to find Bright Distant Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A remote galaxy shining with the light of more than 300 trillion suns has been discovered using data from NASA’s Wide-field Infrared Survey Explorer (WISE).

The galaxy is the most luminous galaxy found to date and belongs to a new class of objects recently discovered by WISE — extremely luminous infrared galaxies, or ELIRGs.

“We are looking at a very intense phase of galaxy evolution,” said Chao-Wei Tsai of NASA’s Jet Propulsion Laboratory in Pasadena, California, lead author of a new report appearing in the May 22nd issue of The Astrophysical Journal. “This dazzling light may be from the main growth spurt of the galaxy’s black hole.”

Montgomery County Sheriff's Office - MCSOWashington, D.C. – A group of Montgomery County Sheriff’s deputies and a Clarksville Police officer sat around the dinner table during National Police Week last week. They first exchanged stories about Deputy David “Bubba” Johnson, but they soon found themselves discussing the devastating night they lost him.

On January 12th, 2014, Johnson was killed in a crash where his car left the roadway.

They all remember responding to the crash, unable to believe that they had lost one of their own. Some couldn’t finish their stories as tears welled up in their eyes and their voices broke.

NASA’s Mars rover Opportunity completes Martian Marathon in 11 years

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Earth, the fastest runners can finish a marathon in hours. On Mars it takes about 11 years.

On Tuesday, March 24th 2015, NASA’s Mars rover Opportunity completed its first Red Planet marathon– 26.219 miles – with a finish time of roughly 11 years and two months.

“This mission isn’t about setting distance records; it’s about making scientific discoveries,” says Steve Squyres, Opportunity principal investigator at Cornell University. “Still, running a marathon on Mars feels pretty cool.”

NASA experiments show Dark Material on Jupiter’s moon Europa likely Sea Salt

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA laboratory experiments suggest the dark material coating some geological features of Jupiter’s moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation.

The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor — an important consideration in determining whether the icy moon could support life.

The study is accepted for publication in the journal Geophysical Research Letters and is available online.
