What do astronomers do at an observatory?
Before using a research telescope, an astronomer submits a proposal detailing project goals and equipment needs fur approval by a committee of other astronomers. In some cases, even when a project is approved, the astronomer never visits the observatory at all. Instead, telescope specialists operate the instruments and gather data for the astronomer when an astronomer does travel to an observatory, then the engineers, electricians, opticians, computer scientists, cooks and crew who live there prepare for the astronomer’s “observing run,” which typically ranges from two to five nights. The astronomer sleeps through the day, then spends a few hours before sunset preparing for the observations. After dinner, when night falls, the observations begin. The astronomer spends the entire night pointing the telescope at distant objects — planets, stars, nebulae, or galaxies — and collecting the faint trickle of light from each object. A computer stores the data for later analysis. If clouds sp
