@remainhateful: One of the most fascinating discoveries in astronomy is that when you look up at the night sky, you are actually looking back in time. Light travels at a finite speed, so the glow from the Moon takes about 1.3 seconds to reach Earth, while sunlight takes around 8 minutes. The light from many of the stars you can see with your naked eye has been traveling for years or even centuries before reaching your eyes. Some distant galaxies are so far away that their light began its journey billions of years ago, long before humans existed. Every time astronomers observe the universe through powerful telescopes, they are not just exploring distant places—they are also uncovering snapshots of the universe's ancient past. #newzealand #ebba #btarrent
