In the SHARC2
image of ARP 84, the pupil in the eye is barely visible.On the other hand the companion
galaxy shines brightly, suggesting a younger age compared to the main galaxy.What appears to be missing in the
optical and near-IR at the top end of the eye-shaped galaxy is possibly the
dominant feature in the SHARC2 image, signaling the most active sites of
starburst in the system.
