We have surveyed seven symbiotic stars which have extended optical nebulosity, using the Spitzer MIPS detector to obtain images at 24μ and 70μ with resolutions of 3 and 5 arc seconds respectively, covering fields several arc minutes across. The presence of extended optical emission in some symbiotics, in addition to theoretical considerations, suggests that many, if not all, symbiotics may have a history of ejection events. MIPS imagery has allowed a sensitive search for any older, colder dust surrounding symbiotics which could be much more extended than optical emission studies indicate, permitting an investigation of possible ejection events which may not yet have been detected by other means. In addition, cold dust can be a tracer of neutral gas. We have detected 24μ and 70μ extended emission around two of our targets. The sensitivity of this search places a strong constraint on possible extended dust where no emission is detected.
