astrophysical surveys

Astrophysical surveys are systematic investigations that gather data about celestial objects and phenomena across large areas of the universe. Using telescopes and advanced instruments, scientists catalog stars, galaxies, nebulae, and other cosmic entities, often across different wavelengths like visible, infrared, or X-ray. These surveys help us understand the universe's structure, composition, and evolution by providing comprehensive datasets for analysis. They can be targeted or wide-ranging, often involving international collaboration, and serve as foundational resources for many areas of astronomical research and discovery.
