An instrument aboard NASAs recently launched orbiting infrared observatory has found evidence of organic molecules in an enormously powerful galaxy some 3.25 billion light years from the Earth. So powerful is the source, that it is equal to 10 trillion times the luminosity of the sun, making it one of the brightest galaxies ever detected.
The instrument on the newly named Spitzer Space Telescope (previously called the Space Infrared Telescope Facility, or SIRTF) is the infrared spectrograph, or IRS. James Houck, professor of astronomy at Cornell University, heads the scientific team on the $39 million IRS contract with the Jet Propulsion Laboratory, Pasadena, Calif., a division of the California Institute of Technology, manager of the mission for NASA.
Houck participated in a press conference at NASA headquarters in Washington, D.C., today (Dec. 18) at which the first observations and data from the half-billion-dollar observatory, launched Aug. 25, were released. Among the most spectacular details released were dazzling images taken with the space telescopes infrared-array camera and with its multiband-imaging photometer. The images include a glowing stellar nursery; a swirling, dusty galaxy; a disc of planet-forming debris; and organic material in the distant universe.

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...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
