In praise of Spitzer

Launched in 2003, the Spitzer infrared space telescope is past the end of its primary mission. The coolant for the main camera is all used up, but even so there is still important scientific work it can do.

Never quite so visually stunning as Hubble, the results from Spitzer are sometimes astonishing and still worth a look.

The following video from IRrelevant astronomy outlines some of the findings from Spitzer and is presented by Felicia Day and Sean Astin.

Hang on ...

That Felicia Day? This Sean Astin. Yup, seems right (?)
