Title: Jupiter in Infrared
Caption: Infrared image of Jupiter from SOFIA’s First Light flight composed of individual images at wavelengths of 5.4 (blue), 24 (green) and 37 microns (red) made by Cornell University’s FORCAST camera. Ground-based infrared observations are impossible at 5.4 and 37 microns and normally very difficult at 24 microns even from high mountaintop observatories such as Mauna Kea due to absorption by water and other molecules in Earth's atmosphere. The white stripe in the infrared image is a region of relatively transparent clouds through which the warm interior of Jupiter can be seen. A recent visual-wavelength picture of approximately the same side of Jupiter is shown for comparison. (Images are oriented with Jupiter's south pole at the top.)

NASA's Sofia Investigates the Southern Sky from New Zealand
WASHINGTON -- NASA's SOFIA airborne observatory will be based in New Zealand for the next two weeks, taking advantage of the Southern Hemisphere's orientation to study celestial objects that are difficult or impossible to see in the northern sky.
SOFIA, formally known as the Stratospheric Observatory for Infrared Astronomy, deployed to the United States Antarctic Program's facilities at Christchurch International Airport last week and completed its first science flight at 4 a.m. local time July 18 (noon EDT July 17). A team of scientists, engineers, pilots and technicians from the United States and Germany are deployed with SOFIA to support as many as nine research flights through Aug. 1.
SOFIA is a modified Boeing 747SP aircraft that carries a telescope with an effective diameter of 100 inches (250 centimeters). It provides astronomers access to the visible, infrared and submillimeter spectrum.
On the first flight in New Zealand, astronomers used SOFIA to observe the disk of gas and dust orbiting the black hole at the center of our Milky Way galaxy, and two dwarf galaxies, the Large and Small Magellanic Clouds, which accompany the Milky Way. The Magellanic Clouds can be seen easily with the naked eye in the southern sky.
"SOFIA's deployment to the Southern Hemisphere shows the remarkable versatility of this observatory, which is the product of years of fruitful collaboration and cooperation between the U.S. and German space agencies," said Paul Hertz, director of NASA's Astrophysics Division in Washington. "This is just the first of a series of SOFIA scientific deployments envisioned over the mission's planned 20-year lifetime."
A vital part of the collaboration is a far-infrared spectrometer, the German Receiver for Astronomy at Terahertz Frequencies (GREAT). Mounted on SOFIA's telescope for the entire deployment, GREAT is especially suited for studies of interstellar gas and the life cycle of stars.
"The success of the GREAT spectrometer in addressing exciting scientific questions at far-infrared wavelengths was demonstrated during SOFIA's earlier, Northern Hemisphere flights," said Rolf Guesten of the Max Planck Institute for Radio Astronomy in Bonn, Germany, and leader of the German researchers who developed the spectrometer. "Now, we are turning the instrument to new frontiers such as the Magellanic Clouds, including the Tarantula Nebula -- that is the most active star-forming region known in the local group of galaxies."
SOFIA project scientist Pamela Marcum said the results anticipated from observations made during the aircraft's deployment will further scientists' understanding of star formation, stellar evolution and chemistry in stellar clouds.
"The deployment exemplifies the synergistic relationship between SOFIA's international partners, with NASA playing a crucial role in the planning and execution of the science observations," Marcum said.
SOFIA is a joint project of NASA and the German Aerospace Center, DLR. The aircraft is based at NASA's Dryden Flight Research Center's Aircraft Operations Facility in Palmdale, Calif. Dryden manages the program. NASA's Ames Research Center in Moffett Field, Calif., manages SOFIA's science and mission operations in cooperation with the Universities Space Research Association (USRA) of Columbia, Md., and the German SOFIA Institute (DSI) at the University of Stuttgart. The National Science Foundation's U.S. Antarctic Program provided vital support for SOFIA's deployment operations in Christchurch.

NASA's SOFIA Featured in the Astrophysical Journal Special Edition :

MOFFETT FIELD, Calif. -- The Astrophysical Journal, a leading professional astronomy research publication, will issue a special edition of its Letters volume on April 20 with papers about observations made with NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne telescope.

SOFIA is a highly modified Boeing 747SP aircraft that carries a telescope with a 100-inch (2.5-meter) diameter reflecting mirror that conducts astronomy research not possible with ground-based telescopes. By operating in the stratosphere at altitudes up to 45,000 feet, SOFIA can make observations above the water vapor in Earth's lower atmosphere.

"This is really SOFIA's debut on the world scientific stage," said Chris Davis, SOFIA program scientist at NASA Headquarters in Washington. "World-class observatories such as the Hubble, Chandra and Spitzer space telescopes had their Astrophysical Journal special editions, and now SOFIA joins their prestigious ranks."

The eight SOFIA papers featured in the special edition cover diverse research on topics including SOFIA's capabilities as a flying observatory and its study of star formation in our galaxy and beyond.

Studies of star and planet formation processes are one of SOFIA's 'sweet spots,'" said SOFIA Science Mission Director Erick Young. "SOFIA's infrared instruments can see into the dense clouds where stars and planets are forming and detect heat radiation from their construction material. By getting above the Earth's atmospheric water vapor layer that blocks most of the infrared band, SOFIA's telescope can view the glow from forming stars at their strongest emission wavelengths."

The infrared images analyzed in these papers were obtained with the FORCAST (Faint Object Infrared Camera for the SOFIA Telescope) instrument during SOFIA's first science observations in December 2010. Papers based on observations with SOFIA and the GREAT spectrometer (German Receiver for Astronomy at THz Frequencies) will be published in a May 2012 special volume of the European journal Astronomy and Astrophysics.

SOFIA is a joint project of NASA and the German Aerospace Center and is based and managed at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif. NASA's Ames Research Center at Moffett Field, Calif., manages the SOFIA science and mission operations in cooperation with the Universities Space Research Association, headquartered in Columbia, Md., and the German SOFIA Institute at the University of Stuttgart.

NASA Selects Science Instrument Upgrade For Flying Observatory :
WASHINGTON -- NASA has selected a science instrument upgrade to the Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne observatory. The instrument, the High-resolution Airborne Wideband Camera (HAWC), will provide a sensitive, versatile and reliable imaging capability to the SOFIA user community. The upgrade involves two proposals that will allow the observatory to measure the structure and strength of magnetic fields in diverse objects throughout the universe, such as star-forming clouds and galaxies. This will help astronomers better understand how stars, planets and galaxies form and evolve.

"SOFIA has the ability to become a world-class airborne observatory that complements the Hubble, Spitzer and Herschel space telescopes," said John Grunsfeld, NASA's Science Mission Directorate associate administrator. "This upgrade will greatly broaden SOFIA's capabilities.
"Last August, the agency released an Announcement of Opportunity for SOFIA second-generation instrument investigations and received 11 proposals. The selected proposals were judged to have the best science value and feasible development plans.
The selected proposals are:
-- The High-resolution Airborne Wideband Camera Polarization (HAWC-Pol), Charles Dowell, principal investigator, NASA's Jet Propulsion Laboratory, Pasadena, Calif. This investigation upgrades the HAWC instrument to include the capability to make polarimetric observations at far-infrared wavelengths. The investigation's main goals are to measure the magnetic field in the interstellar medium, star forming regions and the center of the Milky Way.
-- HAWC++, Johannes Staguhn, Johns Hopkins University, Baltimore. This investigation will provide a sensitive, large-format detector array to the HAWC-Pol investigation, increasing its observing efficiency and providing a broader range of targets.
