It takes that long for the light depicting the event, to get here. If a star is 1,000 light-years away, that means it will take 1,000 years for the light depicting the event to get here. In other words, we see it as it was 1,000 years ago.
Light dosent travel to us that quickly and it's so far away that the light takes so many years or so to arrive here for us to see.
When a distant star explodes, the light and other radiation from the event must travel long distances to reach Earth. This can take years or even centuries, depending on the distance of the star. Once the light reaches us and is detected by telescopes, scientists can then confirm that a star has exploded.

Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies.

When did a supernova actually occur if it happened in a galaxy 160000 light years away?
If a supernova occurred in a galaxy 160,000 light years away, we would see the event 160,000 years after it happened due to the time light takes to travel that distance. So, if we observe a supernova today in that galaxy, it actually occurred 160,000 years ago.
