🪐 When astronomers observe a star like Betelgeuse in the constellation Orion, the light reaching Earth has traveled 642 years—limited by the constant speed of light, which is 299,792 kilometers per second. This means we never see stars as they are now, but as they were centuries or even millennia ago, so every starlit night is filled with messages from the deep past of our universe. ✨ #speedoflight⚡#betelgeuse⚡#spacedistances⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
