NIRCam, the 0.6 to 5 micron imager for NASA's new James Webb Space Telescope, or JWST, was designed by scientists at the University of Arizona. The NIRCam Engineering Test Unit passed its test phase at Lockheed in Palo Alto, Calif., where it was constructed, and is being shipped to the NASA Goddard Space Flight Center in Maryland.
It is due to arrive there on Monday, May 3.
With its 6.5 meter (21-foot) mirror, JWST will look for the first light-emitting galaxies and star clusters that formed in the universe after the Big Bang. The NIRCam design is optimized for finding first light sources, peering through clouds of dust in space that obscure these objects.
"The camera also includes features that will make it a wonderful tool for studying star formation in the Milky Way Galaxy and for discovering and characterizing planets around other stars," said Marcia Rieke, an astronomer and professor at the UA Steward Observatory and a principal investigator for the JWST.
The test unit at Lockheed includes one fully functional optical channel and was used to demonstrate that the hardware that will be used in aligning JWST's mirror segments will work.
The JWST, formerly known as the Next Generation Space Telescope, is due to launch in 2014.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
