We present two adjacent jet candidates with a length of \sim 9 \degr 
each – 10 \times longer than the largest known jets – discovered by us on 60 \mu m and 100 \mu m IRAS maps , but not observed at any other wavelength .
They are extremely collimated ( length-to-width ratios 20–50 ) , curved , knotty , and end in prominent bubbles .
Their dust temperatures are 25 \pm 3 K and 30 \pm 4 K , respectively .
Both harbour faint stars , one having a high proper motion ( 0 \aas@@fstack { \prime \prime } 23 yr ^ { -1 } ) and being very red , suggesting a distance of \sim 60 pc .
At this distance , the combined mass of both jets ( assuming a gas-to-dust ratio of 200 ) totals \sim 1 M _ { \sun } .
We suspect that these gigantic ( \sim 9 pc length ) jets have a common origin , due to the decay of a system of evolved stars .
They are the first examples of jets radiating in the far IR and might be the closest non-diffuse nebulae to the solar system .
