Virtual Astronomy Laboratory

Computer Based Labs for Introductory Astronomy

Many of the astronomical observations and measurements which are of interest in intro astronomy labs are not practical for a variety of reasons, including equipment restrictions, complexity, and night time viewing requirements. The 25 computer-based labs contained in Virtual Astronomy Laboratory are designed to give students a simulated view of the sky, allow them to make measurements on the computer, and analyze the data they have collected. Virtual Astronomy Laboratory brings a hands-on experimental lab component to astronomy courses, and requiring only basic math skills on the student’s part, the carefully selected collection of labs are appropriate for introductory astronomy courses at the high school and college level.

Virtual Astronomy Laboratory puts some of astronomy’s most useful instruments into the hands of students - precise telescope controls to measure angular size; a photometer to measure light intensity; and a spectrograph to measure Doppler-shifted spectral lines. Time-lapse and time-exposure photographic observing methods are also simulated.

Each lab activity provides everything required to perform a thorough investigation from start to finish - (1) Lab manual which includes background information and step-by-step instructions, (2) interactive simulations for hands-on data collection, and (3) on-screen assistance including input fields allowing students to enter and check their results.
