Stephen Sekula (steve)'s status on Thursday, 30-Jan-2020 09:50:53 EST Stephen Sekula Bittersweet day. NASA says farewell to its Spitzer Space Telescope. We will miss you, @NASAspitzer. I just used images from this telescope to show the Crab Nebula expansion in my #PHYS3305 class. https://www.latimes.com/science/story/2020-01-30/nasa-spitzer-space-telescope-retires
