What are the astronomical instruments and their uses?
The main astronomical instruments are the armillary sphere, the triquetrum, the quadrant, the astrolabe, and the various kinds of telescopes. These instruments are all used to observe, measure, and study celestial bodies. They can be used to collect data on planets, galaxies, radiation, stars, nebulas, etc.
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.
Why the astronomers observe stars?
Stars are like the bread crumbs left by the Big Bang. By studying stars scientists get to know the elements that are found in them and how are they connected to us. They also teach us the way the universe works. They illuminate the darkest secrets of the universe.
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
What is A PERSon who studies planets and galaxys?
A person who studies planets and galaxies is called an astronomer. Astronomers observe and analyze celestial bodies such as planets, stars, and galaxies to understand their composition, behavior, and evolution. They use telescopes and other instruments to gather data and make scientific discoveries about the universe.
Who studies the stars moons and planets?
Astronomers study stars, moons, and planets. They observe, analyze, and interpret data gathered from telescopes and other instruments to learn more about the universe.
What are scientists called who study the Universe?
Scientists who study the Universe are called astronomers. They use telescopes and other instruments to observe and analyze celestial objects like stars, planets, galaxies, and black holes. Some astronomers also study the fundamental forces and laws that govern the Universe.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
How do radio waves help astronomers?
They are simply one more way to observe distant objects and events.
Why do astronomers depend on technology?
Back in the older times astronomers didn't have our current instruments, but as time went on technology advanced and made it easier for astronomers to do what they do. But to answer your question astronomers depend on Technology because they want accurate observations and plus like i said earlier it is easier to use technology.
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.

What is the name is people who studies the stars?
People who study stars are called astronomers. They observe and analyze celestial objects and phenomena, including stars, planets, galaxies, and more, to better understand the universe.
What does the Astronomers use to observe the sky?
a stethoscope
Which planet rings were discovered in 1977 when the planet occulted a distant star?
The rings of Uranus were discovered in 1977 when the planet occulted a distant star. This event allowed astronomers to observe a series of fading and brightening of the star's light, indicating the presence of rings around Uranus.
How do astronomers observe the spiral of the milky way?
by eyes
