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 is the best telescope?

User Avatar

Asked by Wiki User

"Space" is actually a pretty boring thing to examine, since there's nothing there. What you probably want is to examine things in space, and what kind of telescope is "best" depends on exactly what those things are.

I've added a link to a website intended for newcomers to the hobby that details the sorts of tradeoffs in the various types of (optical) telescopes so that you can choose one that works for what you're interested in looking at.

Why is it possible to eavesdrop without being seen?

User Avatar

Asked by Wiki User

It is possible to eavesdrop without being seen because there are various methods of surveillance and communication interception that do not require physical visibility. These methods include wiretapping phone lines, utilizing hidden cameras or microphones, and hacking into electronic devices or networks. Additionally, advancements in technology have also made it easier for eavesdroppers to remotely monitor conversations or data without being physically present.

What telescope allows us to see through dust clouds and observe star formation?

User Avatar

Asked by Wiki User

The Hubble Space Telescope is able to observe star formation even in the presence of dense dust clouds. It is equipped with instruments that can detect different wavelengths of light, including ultraviolet and infrared, which can penetrate through the dust and provide clear views of star-forming regions. This allows scientists to study and understand the process of star birth in greater detail.

What is the advantage of using a concave mirror in the place of convex lens as objective in a telescope?

User Avatar

Asked by Wiki User

Using a concave mirror as the objective in a telescope offers several advantages over a convex lens. First, it eliminates chromatic aberration, which is the distortion of colors in an image caused by a lens. Second, it allows for a wider field of view. Lastly, it is easier to manufacture large mirrors compared to large lenses, making it more practical for telescopes with larger apertures.

Arecibo radio telescope is laid out like which optical telescope design?

User Avatar

Asked by Wiki User

The Arecibo radio telescope is not laid out like any specific optical telescope design. It is a unique design called an "active spherical reflector" where the dish itself is spherical in shape and fixed in position. This design allows for a large collecting area and a high sensitivity to radio signals.

If telescope mirrors were made in odd sizes the one with the most lightgathering power would be?

User Avatar

Asked by Wiki User

the largest odd-sized mirror with the largest surface area. This is because the larger the mirror, the more light it can collect and focus, resulting in increased light-gathering power. The odd size does not directly affect the light-gathering power, but the mirror's surface area is the determining factor.

What makes a telescope more powerful?

User Avatar

Asked by Wiki User

Several factors contribute to the power of a telescope. The size of the objective or primary mirror is a crucial factor, as a larger diameter allows the telescope to capture more light. The quality of the optics and the level of precision in their construction also affect the power of a telescope. Additionally, the type and quality of the eyepiece used can further enhance the power by magnifying the image.

Which planet is easiest to spot using a telescope?

User Avatar

Asked by Wiki User

The planet easiest to spot using a telescope is usually Jupiter. Its large size, bright coloration, and distinctive cloud bands make it easily distinguishable even with a small telescope. Additionally, Jupiter's four largest moons, known as the Galilean moons, can also be seen with a telescope.

Why telescopes that detect non optical radiation are useful for studying objects in space?

User Avatar

Asked by Wiki User

Visible light is a very narrow range of the electromagnetic spectrum. Even audible sound, at the very bottom, is part of this EM spectrum. Radio and other types of 'scopes are designed to 'see' these other ranges, often with surprising results. The space telescope employs more than visible light capabilities, as do many Earth and space-bound telescopes. Looking at Saturn in visible light is quite breath-taking, but in ultra-violet (UV) a remarkable geometric pattern is visible on one of its poles.

On what is the SOHO space telescope targeted?

User Avatar

Asked by Wiki User

The SOHO space telescope is primarily targeted towards studying the sun. It observes the sun's interior, atmosphere, and solar wind, and helps scientists understand various phenomena such as solar flares, sunspots, and coronal mass ejections. Additionally, SOHO also observes comets, asteroids, and other celestial objects in its field of view.

What is the radio interferometer?

User Avatar

Asked by Wiki User

A radio interferometer is a scientific instrument used to observe and study radio waves emitted by celestial objects such as stars, galaxies, and quasars. It consists of multiple radio antennas or dishes that are spread out over a large area and work together to create a combined signal. By combining the signals from different antennas, a radio interferometer can create high-resolution images and precise measurements of radio sources in the universe.

How do I build a simple telescope?

User Avatar

Asked by PranavPadavu

A simple Galilean telescope consists of a plano convex lens for the objective (front) and a plano concave for the eyepiece. An easy way to make one is to find the optics (lenses) first. You'll need to determine the focal length for the objective, as this will give you an idea of how long the tube needs to be. Once you've obtained your optics, you'll need to make the tube. The simplest method is to simply use two cardboard tubes, one that slides inside the other. The larger tube will hold the objective lens. Make sure that the flat surface of the objective is to the inside of the tube. There are several ways you can fix this into place, such as making cardboard rings or slightly smaller tubes ahead and behind the lens. Next, you'll need to mount the eyepiece into the second "focuser" tube. Again, make sure that the flat side of the lens is facing into the tube, and again you can use the same method used to mount the objective. Once both tubes are finished, you can slide the focuser tube into the main tube. You may need to decrease the inner diameter of the main tube so that the focuser does not sit loose. You can use more cardboard for this, and even felt for an inner layer to help the focuser move. Remember, as with all telescopes, basic safety; never look at the Sun.

Why do astronomers currently prefer orbiting telescopes over earth based telescopes?

User Avatar

Asked by Wiki User

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 the most major difference between telescope and microscope?

User Avatar

Asked by Wiki User

A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
