Looking at distant stars allows us to look back in time because light takes time to travel across vast distances in the universe. When we observe a star that is, for example, 1,000 light-years away, we are seeing the light that left it 1,000 years ago. This means we are witnessing the star's past state rather than its current one. As a result, the farther away a star is, the further back in time we are looking.

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 do you mean by blue stars shiver in the distance?
This phrase likely refers to the twinkling effect observed when looking at distant stars through Earth's atmosphere. The twinkling, or shivering, of blue stars is caused by the turbulence in the atmosphere bending and scattering the starlight as it reaches our eyes.
What is the main use of the telescope?
to see a distant objects..like stars..
Do nearby stars have larger angles than distant stars have?
Yes, nearby stars generally have larger parallax angles than distant stars. Parallax is the apparent shift in the position of a star when observed from different points in Earth's orbit around the Sun. The closer a star is to Earth, the greater the angle of this shift, making it easier to measure compared to more distant stars, which exhibit much smaller angles due to their greater distances.
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..
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 do people say looking at stars is like looking in the past?
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
When was Distant Stars created?
Distant Stars was created in 1981.
How many pages does Distant Stars have?
Distant Stars has 352 pages.
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 the true shape of stars?
Stars are distant suns, which are roughly spherical in shape.

Why do you see the stars at night?
Stars are visible at night because the Sun has set, creating a dark sky that allows the stars' light to be visible. When it is dark enough, our eyes can adjust to the lower light levels and perceive the light emitted by distant stars in the night sky.
Distant radio sources that resemble stars?
quasars
