How many stars can you see in the night sky with your naked eye? A million? A Billion? As Carl Sagan liked to say, “Billions and billions?” On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are investigating how many stars you can really see.
Neil explains why the number of stars you can see might be drastically lower than you think. Find out why the Moon poses a problem for seeing stars. Neil tells us how a full Moon can wash out a good amount of visible stars. Find out more about “dark time” and “bright time” when using telescopes.
We discuss how binoculars can help you see a lot more stars. We dive into the evolutionary history of our eyesight. Also, Neil gives us a way to use your fist to calculate how many stars you can see in the sky. Lastly, discover more about how Andromeda went from being what we thought was a simple nebula to an entire other galaxy.
