We present infrared observations of the young , oxygen-rich supernova remnant 1E 0102.2-7219 ( E0102 ) in the Small Magellanic Cloud , obtained with the Spitzer Space Telescope .
The remnant is detected at 24 \mu m but not at 8 or 70 \mu m and has a filled morphology with two prominent filaments .
We find evidence for the existence of up to 8 \times 10 ^ { -4 } M _ { \odot } of hot dust ( T _ { d } \sim 120 K ) associated with the remnant .
Most of the hot dust is located in the central region of E0102 which appears significantly enhanced in infrared and radio continuum emission relative to the X–ray emission .
Even if all of the hot dust was formed in the explosion of E0102 , the estimated mass of dust is at least 100 times lower that what is predicted by some recent theoretical models .
