| Description | It is well-known that supernovae play a key role in creating and distributingelements throughout the universe, but less well-known is their contributionto the overall budget of dust in the ISM. Theoretical models suggest that core-collapse supernovae should produce large quantities of dust, butobservational evidence for this is still debated. Even if significantquantities of dust are produced, does it survive the passage of the reverseshock to enter the ISM? Does the forward shock destroy all dust that it encounters? Near and mid-IR observations with Spitzer and AKARI have begun to answer these questions, but the long wavelength cameras of Herschel are necessary for a complete picture. We propose detailedobservations of G292.0+1.8, a large Galactic supernova remnant (SNR) that has been called the older cousin of Cassiopeia A. One of the few known oxygen-rich remnants, G292 is a 3000 year old textbook example of a core-collapse SNR expanding into its own circumstellar medium (CSM), the wind of a red giant. It is one of the most well-studied SNRs at all wavelengths, from radio to X-rays. At 8. in diameter, it is large enough for the emission from the forward-shock CSM to be well-separated from that of the reverse-shocked ejecta, yet it is still small enough to be fully covered by Herschel in a reasonably small amount of time. We will obtain PACS and SPIRE imaging of the entire remnant. PACS observations will be sensitive to forward-shocked material, while SPIRE data will tell us whetherlarge amounts of ejecta dust are present in the remnant. We will use thefar-IR data in conjunction with X-ray and optical data to obtain a completepicture of the dynamical evolution of the remnant, and advance our understanding of the nature of dust in the universe. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
