The distance is the largest factor, since "normal" optical magnification cannot be used for objects much beyond the solar system. The other concurrent problems are interstellar dust and gas, interference from other luminous bodies, and having to use expensive and complex space-based telescopes.
The light from objects outside our galaxy was actually given off many millions of years ago, so we see images of their distant past.
Factors that limit astronomical observations:
- The atmosphere of the Earth, with its clouds, heat shimmer and of course manmade light pollution, obscures an optical view of dimmer stars. The farther away they are, the smaller the fraction of their light that reaches Earth.
- Radio astronomy, which detects electromagnetic emissions other than visible light, is complicated by Earthbound interference and by emissions from other stars along the same path.
- Another limitation is availability of equipment, even with the greater number of Earth-based telescopes and the latest orbital satellites. New technology is expensive and in great demand.
What else can I help you with?
Do All of the following are reasons why astronomers have difficulty looking at distant stars except?
They don't understand how redshift affects stars.
Reasons why astronomers have difficulty looking at distant stars except?
Light years of dust lanes obscure the view of distant stars in visible light. However, radio telescopes can penetrate the dust and can detect (in the x-ray and infrared spectra) the stars in the core of our galaxy.They don't understand how redshift affects stars.
Which of the following is not a reason that astronomers have trouble viewing distant stars?
Distant stars give off less light
What is not standing in the way of astronomers getting a good view of distant stars?
Forgetting to remove the telescope lens cap is not usually the problem. The answer to this multiple choice question is "red shift" which is actually a useful phenomenon in viewing and analyzing the light from very distant stars. Light is shifted in wavelength by the movement of stars toward or more typically AWAY from the observer, or by moving through strong gravitational fields.
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. By observing how a star's position changes when viewed from different points in Earth's orbit around the Sun, astronomers can calculate the star's distance based on the angle of this apparent shift.
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. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.

What are not a reason that astronomers have trouble viewing distant start?
Astronomers do not have trouble viewing distant stars due to their brightness, as many distant stars are incredibly luminous. Instead, challenges arise from factors like cosmic dust obscuring light, the expansion of the universe redshifting light from distant objects, and limitations of current telescope technology. Additionally, atmospheric interference can hinder ground-based observations, but these issues are not related to the inherent brightness of the stars themselves.

What is the primary source of data on distant stars?
still looking for answers i dont know..
How do astronomers use parallax to describe how we measure the distance to other stars?
Astronomers use parallax to measure the distance to other stars by observing how a star appears to shift its position against the background of more distant stars as the Earth orbits the Sun. By measuring this apparent shift, astronomers can calculate the distance to the star based on the angle of the shift and the known distance between the Earth and the Sun.
Is there a lot of light pollution on Earth that makes it difficult for astronomers to observe at distant stars?
Yes, human electric lighting is polluting the night sky.
