STScI will be down completely for electrical work from 2:00 PM Friday, 2 December – 6:00 AM Monday, 5 December, 2016. Mail will be queued and delivered after the work is completed, but there may be a delay. DADS and data processing won't be up until some time Monday morning. Our apologies for the inconvenience.

Please take a very short 6 question survey found on the front page of the MAST Discovery Portal.

Getting Started

The XMM optical/UV data was provided to MAST starting in 2006. Updates are obtained weekly? from the Guest Observer Facility at HEASARC. The data are accessible using the XMM Search Form. The search results page also has links to the XMM preview pages which allow individual images to be displayed as gif images or using Aladin..
