Why Do Astronomers Always Look at the Same Point in the Sky?

Astronomers can look at the same point of the sky for long periods of time. As well as in the vast universe, While there are so many things to observe.

Of course, looking at the same point so many times There are some reasons behind it. How about taking a look at these reasons together?

Astronomical objects, they are very far away…

such as distant galaxies and quasas (an extremely luminous active galaxy core supported by a supermassive black hole surrounded by a disk of gas) emits very weak light and cannot be detected with short-term observations. There are astronomical items.

In order to see them clearly, it is necessary to look at them for a long time so that weak light sources accumulate. For example, the Hubble Space Telescope was once for weeks By looking at a very small region of the sky, he revealed the most distant galaxies of the universe.

They better examine things that change over time.

Star explosions, movements of matter, supernova explosions It may be necessary to look at the same point for a very long time to understand how events such as these occur.

They also ensure that unexpected events are noticed by continuous observation. If If they kept changing regions they might not have seen these changes.

It is needed to map the universe in detail.

In order to map the universe, elements such as cosmic background radiation and galaxy distribution must be carefully examined, and a certain point must be constantly looked at to examine them. But this way more detailed and accurate results can be obtained.

It should not be forgotten that the margin of error decreases when looking at the same point for a long time. As in all other scientific research; length and repetition of observations, reduces possible errors.
