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.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
