@connorastro: Whenever we look up at the night sky, we are actually seeing the past because light takes time to travel through space. For example, the light from the Sun takes about 8 minutes to reach Earth, so we see the Sun as it was 8 minutes ago. Stars are much farther away, so their light may have taken hundreds or even thousands of years to reach us. This means that when we look at distant stars and galaxies, we are seeing what they looked like long ago, making the night sky like a window into the past. #scary #viral #physics #spacethings #Science
