HST previews are not currently working. We are investigating and apologize for the inconvenience. For image previews we suggest that you try the Aladin option, and for spectral previews the SpecView option. Links to these options are found near the bottom of the preview page. For ACS, STIS and NICMOS grism data you may find the HLA another good option.

About XMM-OM

The Newton X-ray Multi-Mirror Mission (XMM) was launched in December, 1999 with a projected lifetime of 10 years. Although intended primarily as an X-ray observatory, XMM included a small but powerful optical/UV 30 cm telescope co-aligned with the X-ray telescopes for contemporaneous observations. The modified Ritchey-Chretien telescope is capable of detecting 24th magnitude sources in its 17 arcmin field of view. It provides images in the 160-600nm wave band with 1 arcsec resolution.

The links below give more information on the optical detectors used. Users interested in XMM x-ray data should go to the ESA XMM-Newton Science Operations Center
