Telescopes

A telescope is a device used to form images of distant objects. There are two kinds: an optical telescope uses lenses and is known as a refracting telescope or a refractor, and a reflecting telescope, which uses a mirror and is known as a reflecting telescope or a reflector. The earliest telescope was a refractor built by the Dutch eyeglass maker Hans Lippershey. This category is for questions related to telescopes, including using them to view distant planets and objects in space.

What uses a wire mesh as a reflector to collect radiation from space?

A radio telescope uses a wire mesh as a reflector to collect radiation from space. The mesh acts as a surface to focus electromagnetic waves, such as radio waves, enabling astronomers to study celestial objects and phenomena. The collected signals are then directed to a receiver for analysis and interpretation.

Is telescope boon or curse?

A telescope is generally considered a boon as it allows us to observe and study celestial objects that are millions of light years away, providing valuable insights into the universe. However, misuse of telescopes, such as invading privacy or spying on others, can turn it into a curse.

Why are near infrared telescopes located on mountaintops and ultraviolet telescopes in Earth orbit?

Mountaintops are ideal for near-infrared telescopes because the high altitude reduces atmospheric interference and light pollution. Ultraviolet telescopes are placed in Earth orbit to avoid absorption of ultraviolet light by Earth's atmosphere, which allows for clearer observations of objects emitting in the ultraviolet spectrum.

What would be the equivalent single-mirror diameter of a telescope constructed from two serparate 11 m mirrors?

To find the equivalent single-mirror diameter, you would add the individual mirror diameters and then take the square root. So for two 11m mirrors, the equivalent single-mirror diameter would be √(11m + 11m)^2 = √(242) ≈ 15.56 meters.

What are the ethical or moral issues regarding the hubble telescope?

Some ethical or moral issues regarding the Hubble Telescope include the potential risks of space debris generated by its operation, the allocation of resources for space exploration versus other societal needs, and concerns about the impact on indigenous communities or cultures if celestial bodies are exploited for commercial gain. Additionally, there may be questions about the justification for the significant financial investment required to build and maintain the telescope.

How did the hubbles telescope work?

The Hubble Space Telescope works by capturing light from celestial objects using a large primary mirror and then focusing that light onto various instruments for analysis. It orbits Earth to avoid atmospheric distortion, allowing for high-resolution images across different wavelengths of light. The data collected is transmitted back to Earth for scientists to study and better understand the universe.

How does collecting area affect the ability to see faint objects?

A larger collecting area allows more light to be gathered, which improves the ability to detect faint objects. This increased sensitivity results in better resolution and the ability to see objects that might otherwise be too dim to observe with smaller collecting areas.

What is best way to study young stars hidden behind interstellar dust clouds?

One effective way to study young stars hidden behind interstellar dust clouds is by using infrared telescopes. Infrared light can penetrate dust clouds more easily than visible light, allowing astronomers to observe these young stars more clearly. Additionally, combining data from multiple telescopes and techniques, such as radio astronomy, can provide a more complete picture of these hidden stars.

What can radio telescopes see in space?

Radio telescopes can detect and study radio waves emitted by astronomical objects in space, such as stars, galaxies, black holes, and cosmic microwave background radiation. They provide valuable insights into the composition, structure, and behavior of celestial objects that may not be observable through other wavelengths of light.

How do you get to the telescope on shrink ray island?

You go to C.J's room, go left, jump on the dresser,and look for the telescope.

To come back from the desk:

-- climb to the wall thermostat and walk on it to turn it into the red zone

-- go left and push over the wastebasket

-- climb on the papers floating in the updraft

The telescope coordinates for the school are on the bulletin board.

They are 87 (left dial) and 16 (right dial). When you have read C.J.'s secret note (on the kitchen table), you will see her through the telescope. You will need the Morse code book from her bed.

I hope I helped! ;)

Which type of telescope uses grazing incidence?

X-ray telescopes use grazing incidence to focus X-ray photons onto a detector. By reflecting the X-rays at a very shallow angle, these telescopes can overcome the limitations faced by traditional optical telescopes in detecting X-ray emissions from astronomical sources.

What is length of galilean telescope?

Galileo's telescope was about 92.7 centimeters long. 36.5 inches long.

What is refracting glass?

Refracting glass is glass that has been shaped or curved to bend light as it passes through, causing it to converge or diverge. This is used in lenses, prisms, and other optical instruments to manipulate and focus light for various applications such as in microscopes, cameras, and eyeglasses.

What date did they put hubble space telescope in orbit?

The shuttle that would put the Hubble into orbit finally launched on April 24, 1990.

Can telescopes see mars in detail?

Yes, telescopes can see Mars in detail, especially larger telescopes with higher magnification capabilities. Features such as the planet's polar ice caps, surface markings, and even some of its larger geological features can be observed when viewing Mars through a telescope.

Where can I get a telescope in sims social?

You can purchase a telescope in the Sims Social game from the in-game home store under the "Outdoor" or "Hobbies" category. Alternatively, you may also receive a telescope as a reward for completing certain quests or tasks in the game.

Who improve the telescope?

The telescope was improved by several astronomers and inventors over time. Some key figures include Galileo Galilei, who made significant advancements in telescope design in the 17th century, and Hans Lippershey, who is often credited with inventing the first practical telescope in the early 1600s.

How do you get the the coordinates to cjs telescope poptropica?

To find the telescope in Poptropica, you need to go to the main street of CJ's school and use the map to locate the telescope. Once you're there, click on the telescope and interact with it to have a closer look. The coordinates are C-6.

What are the coordinates for the telescope on poptropica?

The coordinates for the telescope on Poptropica vary depending on the island you are on. You will need to provide the specific island you are playing to get the accurate coordinates.

Which telescope was the first to use a honeycomb pattern to avoid the difficulties associated with large mirrors?

The Keck Telescope, located on Mauna Kea in Hawaii, was the first telescope to use a honeycomb pattern on its primary mirror to reduce weight and address some of the challenges associated with large mirrors, such as cooling and handling. This design allowed for a lightweight and more manageable mirror while maintaining structural rigidity and optical quality.

What are the most effective ways of reflecting on your own practice?

Effective ways of reflecting on your practice include journaling your thoughts and experiences, seeking feedback from peers or mentors, and engaging in self-assessment exercises. Reflecting on both successes and challenges can help you identify areas for growth and improvement. Additionally, setting aside dedicated time for reflection regularly can help you make the most of the process.

What is the numbers for the telescope in poptropica?

The numbers for the telescope in Poptropica can vary depending on the specific island you are playing. It is best to consult a walkthrough or guide for that particular island to find the correct numbers needed to solve the telescope puzzle.

What is meant by the size of a telescope?

The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.

Is the design of radio telescopes very similar to the design of refracting telescopes?

No, radio telescopes and refracting telescopes have different designs and functions. Radio telescopes are designed to detect radio waves from space, whereas refracting telescopes use lenses to bend light to create images of distant objects. While both types of telescopes have a common goal of observing the universe, their designs are optimized for different wavelengths of electromagnetic radiation.
