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 NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely ...

I'll admit to using AI for things it was probably never designed for. When my van threw a fault I couldn't immediately figure out—one that seems notorious for trips back and forth to a repair shop—I ended up in a long (but ...

What does it take to catch up with a small, tumbling rock hundreds of thousands of kilometers from Earth? For China's Tianwen-2 mission, the answer was a 400-day chase covering roughly 1 billion kilometers (621 million miles) ...
