    Yes, what you are really seeing is the star twinkling millions of years before that moment. Creepy, huh? That star might not even exist now!

    • You can't see individual stars that are 1 million (+) light years away with your naked eyes.

      If you can see an individual star, it's less than 150,000 years ago. And likely to be a lot less than that.

    • Okay........so I rounded up...a bit. Regardless, you are seeing a star as it existed in the past.
