You are peering into the past as you gaze up at the night sky. The stars you see have travelled infinite distances with their light.
When people talk about "looking into the past," they frequently mean the idea that the majority of the stars in the night sky have long since passed away.
Even moving at a brisk 300,000 km per second, light takes a long time to travel across the vast distances of space.
With a cosmos that old (13.8 billion years), stars should have plenty of time to die. Although this is accurate in theory, it has actually grown into a little bit of a myth in and of itself.
Every star and planet visible in the night sky, including the one you are standing on, is a part of the Milky Way, which is our galaxy.
Given that our sun is located in a galaxy that is around 105,000 light-years across, if you were to observe a star that is said to have already died, it would have to have done so no more recently than 60,000 years ago.
The truth is that we don't actually know which stars are dead; instead, we only know that certain stars are on the verge of dying, heading towards supernova
In addition, the processes of star origination and death alone take millions of years; stars don't simply turn on and off.
