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 Truth Telescope on Sims 2 for PS2?

In The Sims 2 for PS2, the Truth Telescope is an object that allows your Sims to discover other Sims' secrets and motives. Sims can use it to gather information on their relationships or to uncover hidden aspects of other Sims' personalities. It can lead to new interactions and story developments within the game.

Can you get dizzy in space?

The concept of getting dizzy is based on liquid that is somewhere inside your head near both of you ears. When you spin around and around, that liquid keeps swiahing around too. When you stop, the liquid is still spinning, so you still feel like your spinning. That's how you get dizzy. So yes obviously now you can get dizzy in space.

Did Galileo invent the telescope?

Galileo did not invent the telescope, but he made significant improvements to its design and was one of the first to use it for astronomical observations in the early 17th century. The telescope was actually invented in the Netherlands by Hans Lippershey around 1608.

What is a well known space project that uses a gyroscope to operate other than the Hubble telescope?

The Cassini-Huygens mission to Saturn also used gyroscopes to stabilize and control the spacecraft during its mission. Gyroscopes are commonly used in spacecraft to help maintain orientation and stability in the absence of gravity.

Sims 2 How do you Debug telescope?

To debug the telescope in Sims 2, you can press Ctrl + Shift + C to bring up the cheat console, then type "boolprop testingcheatsenabled true" and press Enter. After that, shift + click on the telescope and choose the "Debug" option to fix any issues with it. Remember to turn off the testing cheats after you're done by entering "boolprop testingcheatsenabled false" in the cheat console.

Why did Galileo invent the telescope?

because he wanted to know a way to look at the night sky and the planets up in full detail and much much closer because he was imensly interested in Astronomy and wanted to study the planets.

Can a helicopter work in space?

No, only specially designed rockets can go up into space. As soon as a helicopter reaches our atmosphere boundaries, it would burn up. Rockets on the other hand, have been specially made to hold such extreme temperatures. :)

Why did Isaac Newton invent the telescope?

Isaac Newton did not invent the telescope. The telescope was actually invented by Hans Lippershey in 1608. Newton's contributions to science were in the fields of physics, mathematics, and astronomy, particularly with his laws of motion and the development of calculus.

What state is the HALE telescope from?

The Hale telescope is at the Palomar Observatory, located in Mount Palomar, California.

Can a telescope view be shown on a computer monitor?

Most mid-level and up telescopes have the capability to externally attach a camera in some way. However, this often takes the form of a connection for an old style 35mm film camera. There are moderately-priced computer cameras available which can be used with older 35mm lenses and hardware, and would thus be able to hook up to your telescope with pretty good clarity. Your other option may be to purchase a purpose-built ccd camera unit such as I have linked below. They can be mounted inside the telescope or on it in lieu of an actual eyepiece. These can be very expensive, but will likely give you better results.

How much information does a Hubble Space Telescope hold?

How the telescope works In orbit about 380 miles (610 kilometers) above the earth, the Hubble Space Telescope views the heavens without looking through the earth's atmosphere. The atmosphere bends light due to a phenomenon known as diffraction, and the atmosphere is constantly moving. This combination of diffraction and movement causes starlight to jiggle about as it passes through the air, and so stars appear to twinkle. Twinkling blurs images seen through ground-based telescopes. Because an orbiting telescope is above the atmosphere, it can produce pictures in much finer detail than a ground-based telescope can. This false-color image taken by the Hubble Space Telescope using infrared light shows Uranus's rings and clouds. The different colors in the image represent different atmospheric conditions. Image credit: NASA The Hubble Space Telescope can also observe ultraviolet and infrared light that is blocked by the atmosphere. These forms of light, like visible light, are electromagnetic radiation. The wavelength (distance between successive wave crests) of ultraviolet light is shorter than that of visible light. Infrared light has longer wavelengths than visible light. Ultraviolet light comes from highly energetic processes, such as the formation of disks around black holes and exploding stars. Infrared light provides information about cooler, calmer events, such as the formation of dust clouds around new stars. The United States space agency, the National Aeronautics and Space Administration (NASA), operates the Hubble Space Telescope in cooperation with the European Space Agency (ESA). The telescope is controlled by radio commands relayed from NASA's Goddard Space Flight Center in Greenbelt, Maryland. Astronomers tell the telescope where to point, and computer -- driven instruments aboard the telescope record the resulting observations. The telescope transmits the data by radio to astronomers on the ground. The Hubble Space Telescope has two kinds of instruments: (1) imagers, which take pictures; and (2) spectrographs, which analyze light. Imagers are electronic detectors called charge -- coupled devices (CCD's). The CCD's convert light into electronic signals, which an on -- board computer records and sends to the ground. A spectrograph, like a prism, spreads light into its component colors, much as water droplets spread sunlight into a rainbow. The resulting band of light is called a spectrum (plural spectra). Using spectrographic data from the Hubble Space Telescope, astronomers can determine the composition of stars and galaxies--measuring, for example, the amounts of hydrogen, carbon, and other chemical elements in them How the telescope works In orbit about 380 miles (610 kilometers) above the earth, the Hubble Space Telescope views the heavens without looking through the earth's atmosphere.

What happened on Feb12003 to the space shuttle columbia?

While space shuttle Columbia was lifting off, a piece of Styrofoam the size of a briefcase fell on its wing. It made a hole in it. While reentering Earth's atmosphere, heat got inside the wing. It started making engines offline at mission control and the space shuttle disintegrated over Texas. Everyone died on Columbia. (I don't know how they would survive anyway)

Celestron 102ED refractor telescope When using an Orion 35mm Ultrascopic eyepiece racking the focuser all the way forward still cannot bring a star into focus just almost what is the problem?

I've had this problem with a Skywatcher 120mm refractor and Antares SWA eyepiece. I've heard that there are low-profile 1.25" adapters that you can use with 2" diagonals to give you more inward travel. I'm still searching for one myself. Also some people say aftermarket focusers (ex. Moonlite) may solve this problem.

How much did Chandra telescope cost?

Chandra X-Ray Observatory Cost: Development ~ $1.65 billion Launch Costs ~ $350 million Operations and Data Analysis (years 1-5) ~ $0.75 billion Operations and Data Analysis (years 6-10) ~ $245 million

What did Galileo discover with his telescope?

Galileo discovered the four largest moons of Jupiter (later named the Galilean moons), mountains and craters on the moon, phases of Venus, and sunspots on the sun. These observations supported the heliocentric model of the solar system and challenged the geocentric view of the universe.

Why you use mirrors as reflectors and not alluminium?

Nearly all modern mirrors are aluminum. An aluminum coating is placed on a sheet of polished glass. In common mirrors we observe this aluminum reflector through the glass layer. But if we turn the mirror around, we can bounce light directly off the aluminum, and this is called a "front surface mirror." (Common mirrors have a coating of hard paint over the thin delicate aluminum coating to prevent scratches.) It's perfectly possible to form a mirror by grinding and polishing a thick aluminum slab. But aluminum is softer than glass, and would collect scratches and dings. Also, aluminum is expensive, so an aluminum mirror costing several dollars might replace a glass mirror costing a few cents.

How do four telescopes of diameter 8m each gather as much light as one of diameter 16m?

Four telescopes with 8m diameter each can gather as much light as one with 16m diameter because they can be combined using interferometry techniques to effectively act as a single telescope with the equivalent light-gathering area. By correlating the signals from the individual telescopes, the resolution and sensitivity can be increased as if they were a single larger telescope.

Astronomical telescopes used for viewing visible light may be divided into two general classes refractors and reflectors Describe the main components of each?

Refracting telescopes have a lens at the front to gather light and focus it, while reflecting telescopes use a curved mirror at the back to collect and focus light. The main components of a refracting telescope are the objective lens, eyepiece, and tube, while the main components of a reflecting telescope are the primary mirror, secondary mirror, and housing.

What is the purpose of the lined space next to the handicapped space?

The lined space next to a handicapped parking space is designated as an access aisle and is meant to provide additional space for a wheelchair or mobility device to be loaded and unloaded from a vehicle. This area needs to be kept clear to ensure accessibility for individuals with disabilities.

How does a telescope work?

The telescope has a large diameter concave main mirror with a hole at it's centre.This is known as a Cassegrain configuration. Light from the stars enters the telescope tube and is reflected from the main mirror back up the tube and is then reflected by a small secondary mirror back down through the hole in the main mirror to a focus point behind it.

An array of cameras and spectroscopes share the light by means of a beam splitter at the main focus. The cameras digitally process the images they recieive using charge couple devices known as CCD's or electronic eyes. The digital signals are labelled and sent to a microwave dish which transmit the images back to Earth.

The telescope is powered by solar cells and has a lens cap that automatically closes whenever the sun is a danger to the sensitive cameras.The telescope is remotely pointed and stabilised using gyroscopes and it is these moving parts that are prone to failure.

Despite early problems the Hubble telescope a shuttle space mission was sent to repair the telescope and fit an optical fix known a 'Costar'. The mirror had been ground with an error in the measurement system and ever since has been a fantastic success. It was given major overhaul earlier this year in one of the last shuttle missions and is to be replaced by the James Webb Space Telescope (JWST)in the next decade.

What is focal length?

Focal length is the distance between the optical center of a lens and the image sensor when the lens is focused on a subject at infinity. It determines the magnification and field of view of the lens, with shorter focal lengths providing wider angles of view and longer focal lengths providing narrower angles of view. Focal length is commonly measured in millimeters.

What are the 4 properties of a telescope?

The four main properties of a telescope are its aperture (diameter of the primary lens or mirror), magnification (how much larger the telescope makes distant objects appear), focal length (distance from the lens or mirror to the focal point), and resolution (the ability to distinguish fine details or separate closely spaced objects).
