Release No.: 03-25: First Spectacular Images From SAO's IRAC Camera onSpitzer Space Telescope For Release: 1:00 p.m. EST, Thursday, December 18, 2003
Caption: IRAC scientists named this portion of IC 1396 the "Flaming Ghost" nebula. Located 2500 light-years away in the constellation Cepheus, the Flaming Ghost nebula is a globule of gas and dust about 12 light-years in size. This globule is a remnant of a much larger molecular cloud complex that has formed populous star clusters. Radiation and hot winds from nearby massive, young stars are carving away the nebula like rust sandblasted from an old car. Eventually, it will vanish completely. Credit: NASA/JPL-Caltech/W.

Caption: The spiral galaxy Messier 81 (M81), located 12 million light-years away in the constellation Ursa Major, is a near-twin to our own Milky Way galaxy. In this visible light image, it displays an unremarkable disk and central bulge of stars. Dust lanes wind throughout the disk, hiding details of the galaxy's structure and composition.Credit: N.A.

Caption: IRAC uncovered areas in M81 where star formation is taking place, visible in this image as reddish, infrared-bright clumpy knots within the well-defined spiral arms. The huge amounts of hot dust revealed by IRAC, and the associated hydrogen gas, will provide raw materials for future star formation.Credit: NASA/JPL-Caltech/S.

Caption: Herbig-Haro 46 (HH 46) and its partner, HH 47, show where twin jets of material spew out in opposite directions from a previously hidden source, generating huge shock waves as they plow through anything in their way. The sharp infrared eyes of IRAC exposed the source of these jets - a young protostar embedded in an obscuring cloud of matter.Credit: NASA/JPL-Caltech/A.
