In February of 2010 the Spitzer Science website was redesigned and replaced with a site that is better organized and easier to maintain. Because of this redesign, many URLs changed, and it was deemed impractical to update old news items with new URLs. If you have a question about an event before 2010, please don't hesitate to contact us at the Spitzer Helpdesk.
