astroengine writes “NASA’s Spitzer Space Telescope had the unprecedented opportunity to observe the heart of the Orion Nebula for 40 days, returning 80 images of the star-forming region. In doing so, the observatory has been keeping track of 1,500 young stars as they undergo rapid variations in brightness, caused by large ‘cool spots’ on the surface of the stars and obscuring dust. However, the high resolution images Spitzer is returning take center-stage, showing a tight cluster of stellar birth amid the nebulous clouds of dust. This is an incredible achievement considering its primary mission is over (after using up all of its liquid helium coolant in May 2009) and only two instruments are still working.”

ogre7299 recommends an announcement out of Cal Tech on a milestone for HIFI, the Herschel Space Observatory’s Heterodyne Instrument for the Far Infrared. “The Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. … This detailed-spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) — one of Herschel’s three innovative instruments — demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space. The spectrum, one of the first to be obtained with HIFI since it returned to full health in January 2010 following technical difficulties, clearly demonstrates that the instrument is working well. … [The HIFI instrument had previously been offline since] August 2009 when HIFI experienced an unexpected voltage spike in the electronic system, probably caused by a high-energy cosmic particle, resulting in the instrument shutting down. On 14 January 2010, HIFI was successfully switched back on using its spare electronics, with science observations commencing on 28 February.”

The new VISTA telescope has captured a stunning image of the Orion nebula. By imaging in the infrared, the telescope can see through the dust that normally hinders our view.
