Light gets dimmer as you get farther away from a source according to the inverse square law (like in the previous question). Why do you think it is so challenging for astronomers to view stars and galaxies that are millions or billions of light years away from Earth?


Sagot :

astronomers have a difficult time viewing stars and galaxies millions or billions of light years away because they're just so far away. based on the number of light years they are away, that number represents how long the light from that object took, in order to reach that astronomers eyes. so in reality, they're looking at the past when studying objects that insanely far away. if a star is 1 million light years away, that means the light from that star will take 1 million years to reach your position. so considering the distance that an object is in space and relative to an astronomers position, it's quite expected for it to become harder to view. the farther an object is from sight, the harder it is to see.

i hope this helps!
