Observational Astronomy and Telescope Technology

Observational astronomy focuses on gathering and analyzing data from celestial objects using telescopes and other instruments. It involves observing electromagnetic radiation from stars, galaxies, and other phenomena across multiple wavelengths radio, infrared, visible, ultraviolet, X-ray, and gamma-ray. Ground-based and space-based observatories work together to provide a more complete view of the universe.

Advancements in telescope technology such as adaptive optics, segmented mirrors, and interferometry have revolutionized observational capabilities. Instruments like the James Webb Space Telescope and the Extremely Large Telescope allow astronomers to look deeper into space and further back in time, uncovering cosmic structures and events that were previously beyond reach.
