Telescopes

This distance is more than 600 miles -- too far for a land-based telescope to be useful.

A spectroscope operates by dispersing light into its different wavelengths, typically using a prism or diffraction grating. This separation allows scientists to analyze the composition, temperature, and velocity of celestial objects based on the absorption or emission lines in the spectrum.

Venus, Earth, Mars, and Triton (Neptune's largest moon) have carbon dioxide in their atmospheres.

It is 33 METERS in diameter

The questions seems incomplete so I will interpret it to be: which is better to observe with: an x-ray telescope or an infrared telescope.

A telescope is a tool. Tools are designed to do a specific job. Humans eyes are able to see only part of the total light spectrum which physicist and astronomers call the electromagnetic spectrum (EMS). The part of the EMS that we see, we call visible light and runs the colors of the rainbow. Light above or below the range (wavelengths) of visible light can tell us different things about the same object being viewed. Infrared light (radiation) tells us thing about the universe in terms of physical and chemical activity that can occur in the energy (heat) ranges that produce IR light waves while x-ray radiation (x-ray light) does the same thing in the energy (heat) ranges that produce x-rays (light).

Returning to the tool statement, you have a tack and sledge hammer, which hammer would you use to drive a: tack, a railroad spikes? Each tool has its specific purpose, the same with Infrared vs X-ray telescopes. In the case of the two types of telescopes, it is nice to be able to view the same celestial object at different wavelengths of light.

If you are a sci-fi fan think of the classic move: "Predator" with Arnold. The alien viewed the world in infrared vision because it came from a world whose sun emitted light energy predominately in the infrared range of the spectrum (EMS). We use infrared and x-rays for many purposes in medicine can you think of a few instances? The tools using these forms of light do specific functions. Neither one is better than the other, it is a question of what tool is needed.

A dentist examining a patient with a bad tooth using infrared would see an excessive amount of warmth in the area of a bad tooth and if he used x-ray would probably see the bad decay of the tooth which would not be visible with infrared.

The origin of the word "telescope" is

ORIGIN mid 17th cent.: from Italian telescopio or modern Latin telescopium, from tele- 'at a distance' + -scopium (see -scope ).

If you are in the UK just look to the east of your location on any clear evening over the next two weeks, at about 10 degrees above the horizon, and the bright stationary object in the dark sky is the planet Jupiter, and with a decent pair of binoculars you can even see the four Galilean moons in orbit around Jupiter.

In space, there is no interference by Earth's atmosphere.

You would be long dead before you even reached it a black hole has so much gravity you would be long dead before you even got there. Although saying you did survive you would get sucked in like a noodel than hit the core made of the densist pact atoms in the universe.

70 mm. The numbers refer to the diameter of the main lens or mirror; the larger this number, the more light-gathering the telescope is, and also, the higher its resolution will be.

The Hubble Space Telescope never carried any living being. It has been maintained and updated

by astronauts who navigated to it aboard the Space Shuttle, but never served as a vehicle for

anybody's transportation.

In principle, there's no reason why it couldn't be. But it would be prohibitively

expensive, harder to operate mechanically, and tough to match the optical

performance of an equal-sized reflector. That's why, bowing to pragmatism

and practicality, there hasn't been a larger refractor built since the 40-incher

at the Yerkes Observatory was completed in 1895.

A binoscope is a type of binary telescope or long-distance binoculars, used in amateur astronomy or artillery sighting.

The Multiple Mirror Telescope (MMT) was the first telescope to use a honeycomb pattern of smaller mirrors to create the effect of a larger mirror. This design helped to minimize some of the difficulties associated with manufacturing and maintaining large, single-piece mirrors.

The Hubble Space Telescope uses mirrors to gather and focus incoming light. The primary mirror is 2.4 meters in diameter and collects light from celestial objects to produce high-resolution images. Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.

You can't really "observe" a black hole. About the best you can do is look for their effects on their immediate environment, and one of the best tools for that is an X-ray telescope... matter falling into the black hole releases a lot of energy, and some of that comes out as X-rays.

well,both telescopes let you look into the ground into the inner core and you see deep in he atmosphere which is space.

Errr...

The Very Large Array is an array of radio-telescopes, i.e. it detects radio emissions from stars and similar.

An optical telescope as its name suggests, collects visible light.

The similarity is that increasing the aperture increases the radiation-gathering power by a square-law.

In an optical telescope this is achieved by a larger mirror (or lens but most large telescopes are reflecting.)

The VLA uses a "synthetic aperture" to gain the advantages of increasing its gathering area without the cost and complexity of building a single, very large dish.

they are mostly located on mountains if they are near urban areas so that the telescope will have an unhibated at the solar system. In the next town over from mine there is an obserbatory that is located on the ground because their is very little polution or smog and the galaxies are unimpeded. these telescopes search the ends of our universe noy planets likea home telescope will for us amatuer astrometors.

Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.

• Images are not always clear because the light is being bent.
• The size of the lens is limited which limits the power of the telescope.

Fluorescent light is what astronomers call a "bright line" spectrum: there are only specific frequencies that are present, as opposed to the continuous rainbow one sees from a black body source (an incandescent light is basically a black body source).

You can get some idea by holding up a CD in fluorescent light so the light reflects off it and back to your eye, then moving it around a bit. Depending on the type of fluorescent bulb, you'll probably see anywhere from 3 to 5 distinct images of the source, each a different color.

I have no idea and it does not even say it in the textbook

Galaxies are moving away from each other in a constantly expanding universe.
