What does the light astronomers observe through telescopes tell them about galaxies?
The light astronomers observe through telescopes provides crucial information about galaxies, including their composition, temperature, distance, and motion. Different wavelengths of light, such as visible, infrared, and ultraviolet, reveal the presence of elements, star formation rates, and the dynamics of galaxy structures. By analyzing the spectra of this light, astronomers can also determine redshift, which helps measure the galaxy's speed and distance from Earth, offering insights into the universe's expansion. Overall, light serves as a fundamental tool for understanding the nature and evolution of galaxies.

Who looks through telescopes at the stars?
Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.
Can an asteroid be seen?
yes any asteroid can be seen which is in our solar system can be seen.they are very small so they can not be seen through the naked eye(but an asteroid called vesta which was discovered in 1807 is the only asteroid which can be seen).you will need a telescope to see and to observe asteroids but since space is dark and also since asteroids are small and dark we can see them even better through bigger telescopes,radio telescopes, and orbiting telescopes(Hubble).
When scientists look at very distant galaxies through powerful telescopes they see the galaxies as they were millions or billions of year ago. Why is this?
The vast distances involved means that the light we see left those galaxies a long time ago.
How have people observed Halley's comet since 1682?
People have observed Halley's comet through telescopes, spacecraft missions, and by tracking its trajectory through the sky. Amateur astronomers also observe the comet during its periodic appearances every 75-76 years, providing valuable information about its behavior and characteristics.
What is light telescope?
Telescopes that work with visible light, as opposed to other radiations such as infrared, ultraviolet, x-rays, etc.

Used to see stars and planets?
A telescope is used to see stars and planets by collecting and magnifying light from distant objects in the night sky. Telescopes come in different types such as refracting, reflecting, and compound telescopes, each with its own advantages for observing celestial bodies. Professional astronomers and amateur stargazers alike use telescopes to explore the universe and observe objects like galaxies, nebulae, and planets in detail.
Telescopes are used by astronomers for?
To study outer space in greater detail through magnification.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
What evidence do astronomers have that supports the idea that the galaxies are moving away from us?
Observations through telescopes, red shift and several other recordings proves this.
What is optical astronomy?
The term optical telescope refers to telescopes that are used to make observations in the visible light spectrum, that the human eye can see. This is in comparison to such things as X ray telescopes, radio telescopes, etc., which are designed to make observations in parts of the electromagnetic spectrum that are invisible to the human eye.
Can a telescope see through clouds to observe celestial objects?
Yes, telescopes can see through thin clouds to observe celestial objects, but thick clouds can obstruct the view.
Can an asteroid be seen?
yes any asteroid can be seen which is in our solar system can be seen.they are very small so they can not be seen through the naked eye(but an asteroid called vesta which was discovered in 1807 is the only asteroid which can be seen).you will need a telescope to see and to observe asteroids but since space is dark and also since asteroids are small and dark we can see them even better through bigger telescopes,radio telescopes, and orbiting telescopes(Hubble).
Do astronomers spend all their time looking through a telescope and recording their results?
Nowadays, the bulk of the work astronomers do is on computers. They spend a small portion of their time at telescopes actually taking data. Astronomically-useful telescopes rarely have eyepieces you can look through. Radio, ultraviolet, or infrared telescopes collect light that you can't even see with your eye! Telescopes that collect visible light often have electronic cameras called CCD cameras that create an image in a computer. Many telescopes are used to create a spectrum (the light is split into a rainbow, and the brightness of each color is measured). Radio telescopes record signals that astronomers can reconstruct using a computer to make an image or a spectrum.

How do astrologists get their answers when they look through the telescope?
Scientists who look through telescopes are known as Astronomers (Astronomy). Astrologers are those who deal with the divination art of Astrology.
