Interestingly, this control is considered promising for the search of life on exoplanets, since it is possible to observe the signatures of the molecular chirality inherent in biological matter.

How do they know that chirality is intrinsic to exo-life?

Yes, that was just a statement of opinion it seems. I was trying to figure that one also. One would think any such polarization would be smeared out of contention with our present level of astronomical tools. Maybe if we had a Hubble like scope in space but a kilometer wide mirror...
