Humans can see stars almost instantly after they look up at the night sky, as light from the stars reaches our eyes in a matter of minutes to millions of years, depending on the star's distance. However, the human eye takes about 20 to 30 minutes to fully adjust to darkness, allowing us to see fainter stars. This process, known as dark adaptation, enhances our ability to perceive the stars clearly.
