  In this paper, we present a briefly overview of the protoplanetary disks in
the Orion Nebula, incluiding some astrobiological aspects and an H$\alpha$
Fabry-Perot study of 16 of them. We found that Fabry-Perot interferometry
constitutes an effective technique for the detection of proplyds. We also
report heliocentric systemic velocities for the proplyds 82-336, 158-323,
158-326, 159-350, 161-314, 161-324, 163-317, 166-316, 167-317, 168-326,
170-337, 176-325, 177-341, 180-331, 197-427 and 244-440. The velocities were
measured between 22-38 km s$^{-1}$.
