Because starlight takes over four years to reach us from even the neaarest star, we can say we are looking into the past when we look at stars. Therefore some stars might have exploded already but we would not know until their light reached us.
The delay in the apparent positions of Jupiter's four main moons at times when Jupiter was far away was used by Ole Romer to make an early estimate of the speed of light.

Why do people say looking at stars is like looking in the past?
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
