Charae’ interviews assistant astronomer, Prof. Roy Gal, from the Institute for Astronomy at the University of Hawaii, Manoa. Roy works on sky surveys, which are essentially a closer look at the whole sky than is possible with the naked eye. Astronomical surveys generally involve imaging or “mapping” of regions of the sky using telescopes. It’s important to know that a sky survey isn’t always just a picture, like the ones you take on your camera. There are infrared surveys, radio surveys, and much more too. These images allow other scientists, who want to know more about any given star in the sky, a starting point in finding the information they need. What job could be better than observing the sky?
