Furthermore, by studying these processes in various stages across different regions of the universe, astronomers can develop a comprehensive picture of stellar evolution and its role in shaping galaxies.
Studying Black Holes and Dark Matter
Black holes remain one of the most enigmatic phenomena in astrophysics, and JWST is equipped to investigate their properties and influence on surrounding matter. These regions of spacetime exhibit gravitational forces so strong that nothing—not even light—can escape their grasp. By observing the effects of black holes on nearby stars and gas clouds, scientists can infer their mass and behavior.
JWST’s high-resolution imaging capabilities will allow researchers to study supermassive black holes at the centers of galaxies, providing insights into their growth and evolution over cosmic time. In addition to black holes, dark matter poses another significant mystery in modern astrophysics. Although it constitutes approximately 27% of the universe’s mass-energy content, dark matter remains undetectable through conventional means.
Its presence is inferred from gravitational effects on visible matter. JWST’s observations will help map out dark matter distribution by studying galaxy clusters and their gravitational lensing effects on background objects. This research could lead to breakthroughs in understanding dark matter’s role in cosmic structure formation.
