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.

Where did the word telescope come from?
The word "telescope" comes from the Greek words "tele," meaning far, and "skopein," meaning to look or see. So, "telescope" essentially means "far-seeing" or "seeing at a distance."
How is the telescope important to space exploration?
Observing space objects and phenomena, from the ground or from orbit, provides many clues to their characteristics. Since it is not currently possible to visit many locations in space, astronomy can provide insight into the processes at work on planets and stars. In addition to optical viewing and photographs, scientists can examine other non-visible emissions, such as infrared and ultraviolet radiation, x-rays, gamma rays, and neutrinos.
What is the resolving power of a 25Cm telescope?
Resolving power is measured in arc seconds. The formula to find this is as follows:
arc seconds (x) = 11.6/(D)
11.6 is part of the formula
D- is the diameter of the telescope (which you have = 25cm)
Therefore the resolving power should be:
11.6/25 = .46 arc seconds
What do the numbers on a spectroscope represent?
The numbers on a spectroscope represent the wavelengths of light being measured. Each number corresponds to a specific color or frequency of light that is being analyzed by the spectroscope. By measuring the wavelengths, scientists can identify the chemical composition of a substance based on the unique way it interacts with light.
When light travels through the lens of a telescope it is?
focused onto a single point to form an image. This process enables an observer to view distant objects with greater clarity and magnification compared to the naked eye. The quality of the image produced is influenced by the precision and quality of the telescope's optics.
Was Edmund halley the discoverer of Halley's comet?
No, Edmund Halley was not the discoverer of Halley's comet. He predicted the return of the comet, which led to its recognition as a periodic comet and its eventual naming after him. The comet's true discoverer is unknown, as it has been observed and recorded by various cultures throughout history.
What telescope does not use visual light energy?
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light.
Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Why are you asking that, I mean really, does it matter if he is black or white, because if you want him to be black, then just ask yourself first, he's a prisoner....
Alright, now he does have a gental soul, but try enjoying the movie instead of thinking about race.........
I would really appreciate it...........
Thanks!

Who built the first telescope?
The first telescopes were developed independently by Hans Lippershey, a Dutch eyeglass maker, and Zacharias Janssen, his colleague, in the early 17th century. Galileo Galilei is also credited with improving upon their design and using the telescope for astronomical observations.
What kind of telescope is the hubble space telescope?
The Hubble Space Telescope, or HST, or just the "Hubble" for most folks, is a Ritchey-Chrétien reflector telescope. It has a primary mirror to reflect and focus the incident light. A link is provided below.
How old was the Telescope Inventor when he made the Telescope?
The Telescope Inventor, Hans Lippershey, was believed to have been in his 40s when he made the telescope around 1608.
The first telescope didn't look exactly like the ones that we see today, but it was improved though by the famous astronomer Galileo. The first one is said to have been made about 500 years ago.
Will you suggest a good still model for science exhibition?
A good still model idea for a science exhibition could be a solar system model showing the relative sizes and distances of planets. This model can be interactive and engaging for visitors of all ages, providing a visual representation of our cosmic neighborhood. You can also incorporate LED lights to represent the Sun and make it more visually appealing.
The speed of light in glass is the reciprocal of the refractive index of the glass or 1/(refractive index). Not all glass is the same: its refractive index can range from less than 1.5 for Pyrex (a borosilicate glass) to more than 1.9 for (impure) flint glass. This means the speed of light in glass can range between 0.52 and 0.68 of its speed in vacuum.
What are modern space facilities tools and equipment used to study the universe?
Modern tools and equipment used to study the universe include optical telescopes, radio telescopes, space telescopes, the electromagnetic spectrum, many branches of science including paleontology, physics, chemistry, biology, etc., computer science and much much more. For more about tools and equipment used in astronomy, see the related links.
What is the shape of the orbits of most members of the solar system?
round but some rounder than others. Every object is in an orbit which is an ellipse. The planets are in orbits which look almost exactly like circles with an offset centre, but some comets and dwarf planets have orbits with a high eccentricity.
Galileo got his idea for building a telescope from?
Galileo got his idea for building a telescope from hearing about a spyglass. He heard about this device from sailors and was inspired to create his own improved version, which eventually led to the invention of the telescope.
Who was the First person to use refracting telescope?
Thomas Harriot (c. 1560 - 2 July 1621) was an English astronomer, mathematician, ethnographer, and translator. Some sources give his surname as Harriott or Hariot or Heriot. He is sometimes credited with the introduction of the potato to Great Britain and Ireland.[1] Harriot was the first person to make a drawing of the Moon through a telescope, on July 26, 1609, over four months before Galileo.[2] After graduating from Oxford University, Harriot traveled to the Americas on expeditions funded by Raleigh, and on his return he worked for the 9th Earl of Northumberland. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed.
What is meant by the goldilocks zone?
The definition of the "Goldilocks zone" or "Habitable Zone" from Wikipedia [See Link] is "a region of space where stellar conditions are favorable for life as it is found on Earth".
The habitable zone is not to be confused with the planetary habitability.
The term is derived from the fairy story of Goldilocks and the three bears, where she tries the beds, chairs and porridge and finds only one "Just right".
Some people interpret this as meaning "the only zone (conditions) where life can be found" but this is too limiting. Life forms based on silicon, other chemical reactions etc. may have entirely different Goldilocks Zones
Even on Earth life exists outside of what many users of the term would consider habitable. Animals have been found living in the near boiling waters of hot springs, in deep below freezing waters under the Antarctic ice cap, at the -60oC temperatures of the Antarctic surface, without light in caves, in waters with high concentrations of sulfuric acid, and in the deep sea near "black smokers" or volcanic vents,
Radio telescopes have poor resolving power because?
"Poor" is really a woosy adjective.
If you're willing to express the size of the objective mirror in terms of wavelengths instead of
inches or meters or yards, then a radio telescope and an optical telescope with equal diameters
have equal resolving powers.
The familiar difference in their dimensions is simply the obvious consequence of the difference
in the wavelength of the signals they happen to be looking at. The shortest radio waves are
something like 2,000 times as long as the longest light waves.
Telescopes are placed in space to view distant galaxies primarily to?
Telescopes are placed in space to view distant galaxies primarily to avoid atmospheric distortion and light pollution, which can obscure and affect the quality of observations taken from Earth. Space telescopes also provide a clearer and more stable view of the universe, allowing for more accurate and detailed observations of distant galaxies.
How high above the Earth does the Hubble Space Telescope orbit?
The Hubble Space Telescope orbits approximately 547 kilometers (340 miles) above the surface of the Earth. It travels at a speed of about 27,000 kilometers per hour (17,000 miles per hour), completing a full orbit around the Earth roughly every 97 minutes.
Why have no large refracting telescopes been built since 1900?
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
Which us state has the most telescopes in the world A.Colorado B.Arizona and C. Washington?
Arizona is the US state with the most telescopes. The most famous telescope in AZ is the Large Binocular Telescope.
