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.
Why astronomers have difficulty looking at distant star ecept?
Astronomers face challenges when observing distant stars primarily due to the vast distances involved, which can lead to light from these stars being faint and redshifted. Additionally, interstellar dust and gas can obscure their visibility, complicating detection. The Earth's atmosphere can also distort observations, making it harder to obtain clear images. However, advancements in technology, such as space telescopes, help mitigate some of these issues.
How long have astronomers been looking for a new planet?
Since the beginning of astronomy. Astronomers are ALWAYS looking for new things.
What happens to the pupil when looking distant object?
When looking at a distant object, the pupil typically dilates, which allows more light to enter the eye. This process is controlled by the iris and helps improve visual acuity for distant vision. Additionally, the ciliary muscles relax, causing the lens to flatten, further aiding in focusing on objects far away. Overall, these adjustments help the eye to better see and interpret distant images.
Explain how the eye focuses on distant objects?
When looking at a distant object, the ciliary muscles in the eye relax, causing the lens to flatten. This allows the light rays from the distant object to focus directly on the retina at the back of the eye, creating a clear image.

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.

Why are astronomers finding planets with half the mass of Jupiter?
There are three main reasons for this phenomenon: 1). Those objects exist. 2). Technology has advanced to the level capable of identifying them. 3). Astronomers are looking for them.

Since the beginning of astronomy. Astronomers are ALWAYS looking for new things.
Who said that there were other galaxies?
Astronomers, looking at deep space photographs of the Universe.
Do astronomers see distant stars as they were long ago?
Yes. Because they are so far away, the light from the stars takes a long time to reach us (other than our star, the sun, which takes 8 minutes for the light to get here.) That way, a star 8 lightyears away, will be seen as it was 8 years ago.
If you have difficulty knowing where your foot is when you are looking at it you may have a problem with what?
Proprioception
Why are constellation useful for the sky?
they help us "map out" the sky, and almost like sectioning off places so astronomers can say, "the star we are looking at resides in the Draco constellation" and all the other astronomers can have an understanding of the general area they should be looking at
How are spectrums used to study?
Astronomers use the light spectrum of distant objects to determine the chemical composition of those objects. Each element on the period table gives off a different spectrum, and by looking through a spectrometer an astronomer can read the spectrum and figure out what that object is made up of to gain better understanding of our universe.
How did a Sextant work?
It work by looking in a distant look though the glass you can see the sun from where you are at.
Can you tell what the climate of a distant city is just by looking at one day's weather?
yes
