July 10

Today was an interesting day. Our morning intern meeting was transformed into a quick example of how our eyes work. We turned the lights out in the room and allowed our pupils to dilate so we could see ( sort of ) in the dark, then covered one eye and went outside exposing the other eye to light, then back into the room. After that we could see with the eye that had been covered but not with the other. I am supposed to explain this phenomenon in my blog so here goes... when your eye is exposed to light the pupil contracts, reducing the amount of light entering the eye to avoid damage, however, when little light is present the pupil dilates to allow as much light in as possible. As a result, the uncovered eye contracted when we left the room and the covered eye remained dilated, so we could only see effectively with the dilated eye when we returned to the room. After that I spent basically the entire day viewing the images I downloaded and reformatted yesterday. For each one I had to find the galaxy of interest, highlight it and print both a close and far view of the galaxy. Then each printout had to be labeled with the correct image information, galaxy name, and exact coordinates within the image of the galaxy. Overall it was a pretty repetitive day and I am looking forward to Friday and the weekend.
