A very small version of the 20-gigapixel mosaic depicting part of the Milky Way.  The mosaic image was constructed from more than 2 million infrared snapshots taken over the past 10 years by NASA's Spitzer Space Telescope. (NASA)

On March 18, 2014,  NASA officials in Pasadena, Calif unveiled GLIMPSE360, a new website that offers a tour of the Milky Way with a new zoomable, 360-degree mosaic. The mosaic image was constructed from more than 2 million infrared snapshots taken over the past 10 years by NASA’s Spitzer Space Telescope. (NASA)

Engineers working inside the world's largest clean room located at NASA's Goddard Space Flight Center this week installed the Near Infrared Camera (NIRCam), into James Webb Space Telescope.  The NIRCam is considered to be an essential part of the new space telescope that's currently under construction. NASA is looking to launch the state of the art space telescope in 2018.

Researchers at the Georgia Institute of Technology recentlhy used this device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs. (Rob Felt/GA Tech)

This past week researchers at the Georgia Institute of Technology said that they found that aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The researchers used this device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs. (Rob Felt/GA Tech)

Images from NASA's Hubble Space telescope and Chandra X-Ray Observatory were assembled into a mosaic of the galaxy ESO 137-001 (top right) hurtling through massive galaxy cluster Abell 3627 which is some 220 million light years away. (NASA, ESA, CXC)

This mosaic photo, released March 4, 2014, shows the galaxy ESO 137-001 (top right) hurtling through massive galaxy cluster Abell 3627.  The mosaic was made from images taken by NASA’s Hubble Space telescope and Chandra X-Ray Observatory. This region of space is some 220 million light years away from Earth. (NASA)

Artists' reconstruction of Tamisiocaris borealis, an ancient marine animal that lived 520 million years ago during the Early Cambrian period. Research led by the University of Bristol UK that studied fossils of this creature found that they used some rather odd facial appendages to filter their food from the ocean.

Artists's concept of the ATHENA desktop human 'body' that's being built at the Los Alamos National Laboratory.  Scientists there say this device, that combines heart, liver, kidney and lung features, could reduce need for animal drug tests in checking a drug's toxicity. (Los Alamos National Laboratory)
