What else can I help you with?
What feature covers much of the Moon's surface and what did Galileo see when he observed this feature through the telescope?
many craters, mountains, and what Galileo referred to as 'seas'.
How many syllables in the word telescope?
There are 3 syllables in the word "telescope."
How many syllables in telescope?
There are three syllables in the word telescope.(Tel - e - scope).
How many inventions did Sir Isaac Newton invent?
Isaac Newton invented the reflecting telescope (also called a reflector), which uses curved mirrors, instead of lenses, in order to focus light from far away. However, he is not chiefly remembered as a inventor, but rather as a mathematician and theoretical physicist. He is mostly famous for his ideas, rather than for the devices he built.
The primary reason for spreading many radio telescopes across a large area and combining the signals at a central station is?
to increase the resolution of the telescope system. By having multiple telescopes spread out, the system can simulate a larger telescope, which allows for more detailed observations of celestial objects. Additionally, this setup improves the sensitivity of the telescope array, enabling it to detect fainter signals.
When you use a radio telescope what happens?
You are receiving that portion of the electromagnetic spectrum that radios use. It is a much lower frequency than visible light and can detect things that glow at much lower temperatures than stars ... such as gas clouds Many radio telescopes use the 'hydrogen line' at a wavelength of 21 cm. That is one of hydrogen's spectral lines, corresponding to a transition between two high energy levels in the hydrogen atom.
What are the features of the Skyquest XT8 telescope?
The Orion Skyquest XT8 has many unique features that make it one of the most popular telescopes. It has a larger than normal glass reflector, 8" reflector optics, stable base and comes with special software and accessories.
What telescope uses an antenna and a receiver to study the stars?
A radio telescope has an antenna and a receiver to study the stars. Radio waves are part of the same radiation spectrum as light, and they are emitted by many celestial bodies. Analysis of radio emissions can give us information over and above what can be obtained from light.

Does a Space Telescope have an antenna?
Yes. Space telescopes require many radio antennas to transmit their observations back to Earth.
Is a satellite dish a form of radio telescope or antenna?
A radio telescope gathers and focuses radio waves, or electromagnetic waves outside the visual spectrum. A satellite telescope is sent outside the atmosphere to become a satellite of either the earth or sun, unless it is sent outside the solar system like the Voyager spacecraft. Many satellite telescopes carry several types of telescopes in one package to gather as much information as possible, like the Hubble.
How many miles above earth is the Hubble telescope?
The HST orbits at 569 km or 353 miles above Earth.
What feature covers much of the Moon's surface and what did Galileo see when he observed this feature through the telescope?
many craters, mountains, and what Galileo referred to as 'seas'.
How many convex lenses does a refracting telescope have?
At least two, but may have many. Depends on the design of the telescope.
How many syllables in the word telescope?
There are 3 syllables in the word "telescope."
What part of EM spectrum does the arecibo telescope detect?
The Arecibo Telescope can detect radio waves in the radio part of the electromagnetic spectrum, particularly in the microwave frequencies. It is mainly used for radio astronomy research and for studying objects in space that emit radio signals.
Disadvantages of infrared telescope?
The main disadvantage of a radio telescope is the poor resolution of the images they obtain. This isn't due to a flaw in the design, but in a limitation of the radio signals they observe. The longer the wavelength of light (radio waves are light!) the fuzzier the image you receive. In order to combat this, a larger telescope is needed. Radio telescopes are thus the largest astronomical telescopes, measuring hundreds of meters across (e.g. Arecibo radio telescope) or composed of many smaller dishes in large arrays of dozens of radio dishes (e.g. VLBA, Very Long Baseline Array). Another disadvantage is the amount of human generated noise can easily interfere with the telescopes, and is harder to isolate and shield than from light pollution, as it easily reaches beyond horizons and around terrain and obstacles. This can require remote observation sites. They also have many advantages, but that isn't the purpose of this question.
