Multiwavelength observations involve studying astronomical objects or phenomena across a wide range of different wavelengths of light, from radio waves to gamma rays. By collecting data at multiple wavelengths, researchers can gain a more comprehensive understanding of the physical processes at work in the universe. This approach allows scientists to study phenomena such as black holes, galaxies, and supernovae in greater detail and can provide valuable insights into the nature of these objects and their interactions with their surroundings. Multiwavelength observations are often conducted using a combination of ground-based telescopes, space-based observatories, and other instruments to cover the full spectrum of electromagnetic radiation.
