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 would life be without telescopes?

Without telescopes, our understanding of the universe would be limited to what we can observe with the naked eye. We would have a smaller understanding of the vastness of the cosmos, the nature of celestial bodies, and our place in the universe. Science and astronomy would be severely hindered without the ability to observe distant objects and phenomena.

What new telescope is nasa going to launch when the hubble space telescope falls back to earth?

The James Webb Space Telescope is scheduled for launch in 2018.

The Webb telecope is not a direct replacement for the Hubble.

The Hubble has been so reliable since its launch in April, 1990, that

it's expected to function through 2014, and possibly as long as 2020.

What is the best classification for a natural satellite?

The best classification for a natural satellite is based on the object it orbits. For example, Earth's moon is classified as a natural satellite because it orbits Earth. Natural satellites can also be classified based on their size or composition.

What landmark is found west of the reflecting pool?

The Washington Monument is located west of the reflecting pool in Washington, D.C.

Why astronomers uses telescope if you can see the planet by naked eyes?

With a telescope, you can see a lot more detail on the planets surface. Without a telescope you can only see bright dots, like surrounding stars, but with a telescope you can make out more - you can see the rings of Saturn for example of the bands and red spot on Jupiter.

How much does a telescope that can see neptune cost?

Telescopes that can see Neptune typically range in price from a few hundred to several thousand dollars, depending on the quality, size, and features of the telescope. High-quality telescopes with advanced features will generally cost more.

Why would you use telescopes to see planets?

Telescopes allow us to see planets in greater detail, revealing their features such as surface markings, moons, and rings. They also help astronomers study planetary atmospheres, temperatures, and compositions, providing valuable information about these celestial bodies. Telescopes enable us to observe planets from great distances and gather data that may not be possible with the naked eye.

How a man can be a martian?

firstly you should know about it that what is a martian...actually a martian is that person which live on mars....a man can be a martian as i am a martian.....as you all know science is so vast and is now at high lebel of technology.many of mars rovers are gong to mars by NASA..which take the names and pics of the persons on mars and make them a martian and add them in the name of istory.in the result of which they indicate a certificate too to the person which have ability to be a martian.

What kinds of telescopes are used to see stars in visible light?

Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.

Can you see Antares in a telescope?

Antares is the 16th brightest star in all the heavens, the 11th brightest normally visible from most heavily populated regions of the Northern Hemisphere. It is a bright orangish star, the brightest star in the fishhook-shaped constellation of Scorpius (not "Scorpio"), and is due south at roughly midnight (standard time) on May 30. The farther south you are the better, but at the time of culmination (midnight May 30), Antares is easily visible to the south from all of the continental US and most of Canada and Europe. Nearly 40 degrees high in Miami (at best), Antares is still easily visible -- at times -- from Calgary -- but doesn't even get above the horizon in Fairbanks.

What are refractor lens?

Good telescopes don't use glass lenses for magnification, because they refract different colors is slightly different angles (known as prism effect), but they use spherical mirrorsinstead. Telescopes with lenses have the advantage of being smaller, cheaper and lighter.

Therefore refracting telescopes use lenses, and reflecting telescopes use mirrors.

What is the name of the process used by the telescopes on earth that allowed them to overcome the effect of the atmosphere blurring caused by the earths atmosphere?

Adaptive optics is the process used by telescopes on Earth to overcome the blurring effect of the atmosphere. It involves using deformable mirrors to correct for distortions in real time, resulting in sharper images of astronomical objects.

Is it true that the clearest images of objects in deep space are produced by a telescope in space?

Yes, telescopes in space, such as the Hubble Space Telescope, are able to capture extremely clear images of objects in deep space. These telescopes are not affected by the distortion caused by Earth's atmosphere, resulting in sharper and more detailed images compared to ground-based telescopes.

How did telescopes improve our knowledge of the universe?

Technology can provide the motivation and direction for scientific research as well as the tools to carry it out.

New technology often requires new understanding; new investigations often require new technology

become more aware that telescopes magnify the appearance of some distant objects in the sky, including the moon and the planets.

The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye.

What type of data does a refracting telescope collect?

A refracting telescope collects light data, which is then focused and magnified by the curved lenses or mirrors inside the telescope. This light data allows astronomers to observe distant objects such as stars, planets, and galaxies.

When did Galileo use the telescope to observe moons?

He was the first to see Jupiter's four largest moons: Ganymede, Callisto, Europa and Io.

These four are now called the Galilean moons in his honor.

Who inveted the first electric telescope?

The first electric telescope was not invented by a single individual, but rather it refers to a telescope that is motorized or has electronic features to aid in its operation. The specific inventor or creators of the first electric telescope are not widely credited or known.

What is the difference between formal telescope and space telescope?

I think that a land-based telescope has the atmosphere as an obstacle for good observations, while the space telescope hasn't, so the images taken are more defined. Moreover, the earth orbit of the space telescope allows it to get a wide range of angles.

What is the name of a placethat uses telescopes and other scientific eguipment to research space and astronomy?

An observatory is the name of a place that uses telescopes and other scientific equipment to study space and astronomy.

The Mount Polamar Observitory in the west of the US is an iconic example.

Today, Earth based observitories are supplimented by space telescopes.

Which method has not yet detected planets around other stars?

Gravitational microlensing has not yet been used to detect planets around other stars. This method involves the gravitational deflection of light from a background star due to the presence of a foreground object, such as a planet, but no planets have been directly detected using this technique.

What does a reflecting telescope use to form images of faraway objects?

A reflecting telescope uses mirrors to form images of faraway objects. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece or camera for viewing.

How many ALMA telescopes are there?

There are a total of 66 ALMA (Atacama Large Millimeter/submillimeter Array) telescopes located in the Atacama Desert in Chile. These telescopes work together as a single interferometer to observe astronomical objects in millimeter and submillimeter wavelengths.

Which shows more detail-a telescope with a resolution of 10 or a telescope with a resolution of 6?

A telescope with a resolution of 10 shows more detail than a telescope with a resolution of 6. Resolution is a measure of an instrument's ability to distinguish between closely spaced objects or features in an image. A higher resolution value means that the telescope can produce sharper and more detailed images.

Is there any negative consequences to being able to see so far in to space?

we are wasting time and money on pointless projects that will not even affect us unless we are announcing our existence to some aliens who want to kill us and that would be stupid because then we'd all die.

Are telescopes and microscopes used by astronomers?

Telescopes are commonly used by astronomers to observe objects in space such as planets, stars, and galaxies. Microscopes are not typically used by astronomers as they are designed for studying very small objects on Earth, such as cells and microbes.
