SIG

SIG, or Synthesis Imaging Grid, is a concept used in radio astronomy to improve the quality of images captured by radio telescopes. It involves combining data from multiple telescopes spread over large distances to simulate a much larger telescope. This collaboration enhances the detail and clarity of the images of celestial objects, much like how combining various pieces creates a clearer picture. By using SIG, astronomers can study distant galaxies, stars, and other cosmic phenomena with greater precision, allowing for more detailed scientific understanding of the universe.
