Astronomers Build Large-diameter Telescopes for Which of the Following Reasons

-The telescope has the highest resolution possible for its diameter. It is easier to make a large reflecting telecope than a large refracting telescope.

The giants of today however have primary mirrors the largest mirrors in the telescope that are 8- to 10-meters in diameter and larger ones are being built Figure 1.

. The diameter is squared because the area of a circle equals πd 2 4 where d is the diameter of the circle. This is a very basic answer and you may be wondering what kind of objects even emit light to begin with. Large telescopes are needed to collect the weak radiation coming from faint or very distant sources.

On the ground astronomers have started building the Large Synoptic Survey Telescope LSST an 84-meter telescope with a significantly larger field of view than any existing telescopes. Generally here are what Astronomers primarily use telescopes to see. It will rapidly scan the sky to find transients phenomena that change quickly such as exploding stars and chunks of rock that orbit near EarthThe LSST is expected to see first light in 2021.

A larger telescope means more light can be gathered and fainter objects can beseen. The job of a telescope is to gather light and bring that light to the eyepiece or camera. The best-known space telescope is also arguably the most famous telescope of all.

Telescopes have three functions 1 to collect more light 2 To resolve close objects 3 To magnify. Benefits of a Bigger Aperture. Ato increase the resolving power bto see fine detail in the image.

- Diffraction fringes are. The Moon the Planets of our Solar System the Sun Deep Sky Objects Comets Stars Light pollution Novae Supernovae and Satellites. To separate two close objects a also we need large aperture So by making large telescopes we can see more faint objects and more deeper into universe.

Gamma-ray telescopes work by absorbing high-energy photons not by reflecting or refracting them. -Further improvements in the quality of the optics would not improve the image. To collect more light we have to build large sized mirrorsThen only we can see very faint objects.

The amount of light a telescope can collect increases with the size of the aperture. The first is size. Telescopes have three functions 1 to collect more light 2 To resolve close objects 3 To magnify.

This image shows one of the primary mirrors of the European Southern Observatorys Very Large Telescope named Yepun just after it was. Bigger telescopes have larger light-collecting area and can achieve better angular resolution. The Hubble Space Telescope HST.

The larger the aperture the brighter the final image will be. If the light-collecting area is large we would be able to detect fainter objects. 6What is the resolution of the Hubble Space Telescope focusing visible light.

Its mirror is 24 meters in diameter. To collect more light we have to build large sized mirrorsThen only we can see very faint objects. The larger the lens or mirror diameter or aperture the more light your scope gathers and.

On the ground astronomers have started building the Large Synoptic Survey Telescope LSST an 84-meter telescope with a significantly larger field of view than any existing telescopes. NASAs upcoming James Webb telescope will boast a primary mirror 65 meters just over 21 feet in diameter but the Thirty Meter Telescope planned for Mauna Kea is well 30 meters more than. Although astronomers such as Spitzer had speculated on the possibilities of a large telescope in space much earlier the HST was launched into orbit in 1990 by the Space Shuttle Discovery and is a joint enterprise of NASA and the.

The bigger the better Why do astronomers want to build large telescope currently the biggest telescope has a diameter of 10 meter. It will rapidly scan the sky to find transients phenomena that change quickly such as exploding stars and chunks of rock that orbit near Earth. Gamma-Ray telescopes are hard to make because they require large lenses or mirrors for focusing in order to make images.

The reason astronomers keep building bigger and bigger telescopes is that celestial objectssuch as planets stars and galaxiessend much more light to Earth than any human eye with its tiny opening can catch and bigger telescopes can detect fainter objects. A telescope with a mirror that is 4 meters in diameter can collect 16 times as much light as a telescope that is 1 meter in diameter. A0047 arc seconds b027 arc seconds cnone of these d024 arc seconds 7Astronomers build large-diameter telescopes for which of the following reasons.

To separate two close objects a also we need large aperture. Unlock all answers Please join to get access. The larger the telescopes aperture the more light the telescope can gather making the image brighter sharper and able to produce more detail.
