A 1 m telescope has a collecting area of pi x 1 x 1 = 1 pi
A 3 m telescope has a collecting area of pi x 3 x 3 = 9 pi.
Therefore, the bigger telescope collects 9 times as much light.

Why are most large telescope reflecting telescopes?

It is cheaper and easier to create mirrors rather than lenses. Large lenses become difficult to support the larger they become. Additionally, mirrored telescopes fold light waves so that a telescope can be shorter, the same size telescopes with lenses are greater in length.


What could you do with a telescope?

With a telescope, you can observe celestial objects such as planets, stars, galaxies, and nebulae. Telescopes allow you to see these objects in greater detail and can also be used for stargazing, astrophotography, and scientific research.


What is the difference between formal telescope and space telescope?

A formal telescope typically refers to ground-based telescopes located on Earth, while a space telescope is positioned in space outside Earth's atmosphere. Space telescopes can observe celestial objects with greater clarity and detail due to being above the distortion caused by Earth's atmosphere, while ground-based telescopes may be limited by atmospheric conditions such as turbulence and light pollution.


For a research telescope (with a long focal length) would the thickness be greater or less than for a backyard telescope (with a short focal length)?

Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.


Instrument used to gaze the stars?

A telescope is an instrument used to gaze at stars in the night sky. Telescopes collect and focus light from distant objects, allowing astronomers and enthusiasts to observe celestial bodies more clearly and in greater detail.

Why do astronomers currently prefer orbiting telescopes over earth-base telescope?

Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.


What do we use to make distant objects appear closer and larger?

If you use warm colors like Red, Orange it would make the objects appear closer than they are


What tools help modern people study objects in space in greater details than was possible in the past?

Modern people use advanced telescopes such as the Hubble Space Telescope, the Chandra X-ray Observatory, and the James Webb Space Telescope to study objects in space in greater detail than was possible in the past. These telescopes allow for high-resolution imaging across various wavelengths of light, enabling scientists to uncover new insights about the universe.

Why does the HST get better pictures than a telescope earth?

The Hubble Space Telescope doesn't get affected by the Earth's Atmosphere. It also has the advantage of being in space so the quality and variety of images are a lot greater then any optical telescopes on Earth.


What are some telescopes names?

The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.


What instrument is used for seeing stars and a planet clearly?

A telescope is commonly used to see stars and planets clearly in the night sky. Telescopes work by gathering and focusing light to magnify distant objects, allowing observers to see them more clearly and in greater detail. Telescopes come in different types and sizes, suitable for various astronomical observations.

Is the telescope manned?

No, telescopes are typically not manned. Observations are often automated or remotely controlled by astronomers to gather data from distant objects in space. This minimizes the risk of human error and allows for more efficient data collection.
