Explore observational astronomy for scientific applications through practical use of optical equipment, satellite tracking, exoplanet hunting, galaxy and black hole studies, spectroscopy, and astrophotography.
Track satellites from the ground with optical imaging, using a wide-field, fast monochrome setup to derive light curves and compare magnitudes from two-line elements.
Learn how exoplanets are hunted with transit photometry and radial velocity, using light curves and Doppler shifts to confirm detections and leverage the NASA exoplanet archive.
Learn how astronomers infer black holes indirectly—from the Milky Way’s Sagittarius A* to active galactic nuclei—using the Event Horizon Telescope, Doppler broadening, and Kepler’s laws for mass estimates.
Explore how a lunar orbiter uses a multi-spectral spectroscopy suite to map surface minerals and guide future mining mission concepts on the Moon.
Apply affordable astrophotography techniques to backyard observing, choosing camera sensors, lenses, and tripods, and using tracking mounts and image stacking to capture the Milky Way, exoplanets, and variable stars.
