Stargazing Through Time #reels #universe #deepspace

When we peer up at the night sky and see those shimmering stars, we're actually taking a trip back in time. The light from those stars travels immense distances to reach us here on Earth. Some of the stars we observe are so far away that the light we see today may have begun its journey thousands or even millions of years ago. This means that when we stargaze, we're essentially looking into the past, witnessing how those stars appeared long before our time.

Here are some fascinating facts about this concept:
1. The light from the nearest star to Earth (besides the Sun), Proxima Centauri, takes about 4.24 years to reach us. So, when we see Proxima Centauri in the night sky, we're viewing it as it was over four years ago.
2. The light from the famous Orion Nebula, which is a stellar nursery where new stars are born, takes around 1,344 years to reach us. So, the light we see from the Orion Nebula actually started its journey during the medieval ages!
3. The most distant galaxy ever observed is GN-z11, located about 13.4 billion light-years away. This means that the light we see from GN-z11 today set off on its journey when the universe was relatively young.
