Telescopes

The reflecting telescope deals with light. It uses mirrors to gather and focus incoming light from distant celestial objects for observation. Sound waves are not used in reflecting telescopes.

Because the Space Shuttle will have to fly at a higher altitude and different inclination that if it was going to the ISS (International Space Station), it will take a little under 3 days to get there. The Hubble Telescope operates past the reach of the Earths Atmosphere, at an orbit of approximately 360 miles above the Earth. Although it could techincally reach it sooner, there is a slight chance that the Space Shuttle may encounter some space junk, especially after the recent collision of two satellites orbitting the planet.

Hand lenses do not refract light themselves. They allow you to see objects more clearly by magnifying them. Refraction of light occurs when light passes through different mediums with varying densities or refractive indexes.

Yes, the Hubble Space Telescope was launched by the United States space agency NASA in 1990. It has provided invaluable insights into our universe and has made countless discoveries in the field of astronomy and astrophysics.

Refraction is the phenomena that occurs when a ray of light changes direction when it passes through a medium with a different refractive index.

This is observable as by submerging an object half in water half out. It looks like at the surface of the water the object, lets say your arm for example, is in the water at a different angle than it is outside of the water.

Microwave transmission also requires line of sight in order to work properly. In order to allow two way communications two frequencies are used. However, this does not mean that there has to be two antennas because the frequencies can be dealt with by one antenna at both ends.

The distance covered by microwave signals is based upon the height of the antenna. In order to increase this coverage each antenna has a built-in repeater that regenerates the signal before passing it on to the next antenna in line. The placement of the antenna to do this is approximately 25 miles.

The main drawback of microwave signals is that they can be affected by weather, especially rain.

The cost of building an observatory can vary widely depending on factors such as size, location, design, equipment, and technology. Small private observatories can cost tens of thousands of dollars, while larger professional observatories can cost tens of millions of dollars. Maintenance, staff salaries, and ongoing operations also contribute to the overall cost.

A hole in the ozone layer would increase the amount of harmful UV radiation reaching the Earth's surface, potentially affecting the sensitive components of a UV telescope. This increased exposure to UV radiation could degrade the telescope's optics and detectors, leading to decreased performance and accuracy of observations. Regular maintenance and protection measures would be necessary to mitigate these effects.

The light collecting power of a telescope depends on the diameter of its objective lens or primary mirror. A larger objective lens or mirror can gather more light, allowing the telescope to produce brighter and clearer images of celestial objects.

Although Galileo's telescope was the first to be used for astronomical purposes, he didn't invent

the telescope.

A man named Hans Lipperhey invented the telescope. Many people claimed to have invented the telescope however Hans Lipperhey was the only one to apply for a patent.

The Hubble space telescope uses optical sensors to gather data of distant objects; as it is located outside of the Earths atmosphere it is not subject to the distortions associated with terrestrial telescopes.

The Chandra (X-ray observatory) gathers x-ray data about the universe; again, this cannot be achieved with terrestrial based observatory instruments

Reflecting telescopes are most commonly used to map the surfaces of planets and moons due to their ability to gather and focus light effectively. These telescopes use mirrors to capture light, providing clear and detailed images of celestial bodies. The larger the mirror, the more detail can be observed.

It only has to remain stable around the 3 axes through its center of mass. That's 'relatively'

easy to accomplish with gyros and heavy flywheels. Once 3-axis stability is achieved, it doesn't

matter where the whole thing goes ... it still stays pointed toward the same field of view for

long exposures. (Just remember to rig a timer to close the shutter when the earth is in that

direction from it, to avoid sunlight or artificial light from the surface being added to the exposure.)

Actually ... you know what ? That may actually be easier in space than it is on the surface

of the revolving earth. Never thought about that before!

there is a refractor and a reflector telescope. refrator is the narrow telescope that works just like a maginifying glass and the reflector telescope takes the image from the lense to the mirror in it's side and thus shows a image. both have their advantages, reflector the narrow telescope is good for viewing objects like planets and moons in the solar system, reflector the wide and short ones are good for stars, nebulas and other bodies out side of the solar system. most scientist and begineers prefer reflector though its a bit more expensive

An artificial telescope refers to a telescope that is man-made and not naturally occurring. They are designed to collect and focus light from distant objects for observation and study. Artificial telescopes can be found in various forms, including optical, radio, x-ray, and infrared telescopes.

Theoretically as far as infinity, it all depends on what one wants to observe. It also depends on how much distortion there is - atmosphere etc.

However, if a mountain is 50 feet from you and it is pitch black, then you cannot see it. If it is day light, then you can see it. Yet if that same mountain is a thousand miles away you may see it as a "feature" of the horizon.

The same with the universe. Some objects are so far away that there is "nothing" to "see" even if they exist.

If there was a star with a luminosity of 500 trillion times that of our Sun located 90 billion light years from Earth then there is a good chance we could observe it. If that same Sun had a luminosity of our own Sun then there is no chance we could observe it.

"See" relies on the ability to observe, based on luminosity and distance.

The word "scope" in microscope refers to the instrument's ability to view objects that are too small to be seen with the naked eye. In this context, "scope" indicates the device's capacity to magnify and visualize tiny objects or details.

Yes, asteroids can be observed by telescopes. Astronomers use telescopes to study asteroids by tracking their movements, observing their size and shape, and even detecting their composition by analyzing the light they reflect. Telescopes on Earth and in space are used for asteroid observations.

Most telescopes are designed for observing distant celestial objects such as stars, planets, galaxies, and nebulae. They are used for tasks like astronomical research, astrophotography, and amateur stargazing.

Mars is made predominantly of rock, mineral, and metallic compounds, much like Earth. While it is cold, it is not "frozen" in the sense that it is made from something that would otherwise be a liquid. It is not an ice planet, for example.

The light from our own sun takes roughly 8 minutes to travel the distance to us. That means when you look up at the sun (don't do that without special glasses) you are looking at the sun as it was 8 minutes earlier. Or you can say you are seeing the sun 8 minutes back in time. The stars which are far away galaxies, the light takes years to reach us. So the light we see at night now can be 100 years old. Or we are seeing that galaxy as it was 100s of years ago.

Radio telescopes extend the sense of sight by detecting and measuring radio waves emitted by celestial objects in space. This allows astronomers to observe objects and phenomena that are not visible with optical telescopes.
