Ground-based astronomy is a research area focused on observing celestial objects and phenomena using instruments located on Earth’s surface, typically at high-altitude, low-humidity sites optimized for atmospheric transparency and stability. It encompasses optical, infrared, submillimeter, and radio observations employing telescopes, interferometers, and advanced detector arrays. Research addresses topics such as stellar and galactic structure, exoplanets, cosmology, and transient events, while contending with atmospheric turbulence, absorption, and light pollution. Adaptive optics, interferometric techniques, and sophisticated data reduction pipelines are central to mitigating atmospheric effects and enhancing spatial and spectral resolution, making ground-based facilities critical complements to space-based observatories.
A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by University of Tsukuba, could uncover between 1 and 10 million dusty star-forming galaxies throughout cosmic ...
