NASA’s Spitzer telescope launched into orbit in August 2003 with the goal of surveying the cosmos in infrared frequencies. Since launch, the incredible instrument has discovered new regions of star formation, has identified the most common ingredients of comets and even located distant supermassive black holes. But on the eve of its 16th anniversary, NASA has unexpectedly posted an update on Spitzer blog, announcing the mission’s end. The solemn message, penned by Spitzer project manager Dr Lisa Storrie-Lombardi, revealed the mission’s end date.
