What else can I help you with?
Are radio waves able to reach the earth?
Yes. This is used all the time by ground-based radio telescopes, which observe outer space.
What types of telescopes can be used at any time of the day and in any kind of weather?
Radio telescopes; however, radio telescopes ARE degraded in bad weather. Electrical storms can damage them, and rain in the dish can attenuate the received signal.
Distance between two radio telescopes?
The distance between two radio telescopes is important for interferometry, a technique used to combine signals from multiple telescopes to improve resolution and sensitivity. By measuring the time delay between the signals received at each telescope, scientists can determine the distance between them and use this information to create detailed images of celestial objects.
Why can only international telescopes operate in space?
That is not the case. While countries may share the cost of launching a telescope into space (and share the time on it), individual countries have launched their own telescopes - eg Hubble is not international, it belongs to NASA/US.
Do astronomers spend all their time looking through a telescope and recording their results?
Nowadays, the bulk of the work astronomers do is on computers. They spend a small portion of their time at telescopes actually taking data. Astronomically-useful telescopes rarely have eyepieces you can look through. Radio, ultraviolet, or infrared telescopes collect light that you can't even see with your eye! Telescopes that collect visible light often have electronic cameras called CCD cameras that create an image in a computer. Many telescopes are used to create a spectrum (the light is split into a rainbow, and the brightness of each color is measured). Radio telescopes record signals that astronomers can reconstruct using a computer to make an image or a spectrum.
Why are stars not been found during the day time?
Simply because the daylight totally masks the far fainter star-light. They are still there, and radio telescopes can still track stellar radio sources.
What is the best clock radio available?
Some people want to know what time it is AND jam to their favorite tunes. If that describes you, then Best Clock Radio Alarm and Weather from Beautiful Clock Radio By I Hate my Clock Radio is perfect for you! If you have a computer, you will always know the time and be able to listen to tunes at the same time.
How much education do you need to be a radio tv announcer?
As you can plainly recognize if you listen to a lot of radio ... not much. It doesn't take a lot of education to know how to operate the console, and even less to be able to open your mouth, read, talk, and tell time. But it does take some education to avoid making a complete fool of yourself when you do eventually open the microphone.
What are the advantages and disadvantages of using different telescopes for astronomical observations?
Advantages of using different telescopes for astronomical observations include the ability to observe different wavelengths of light, which can provide more information about celestial objects. Additionally, different telescopes have varying levels of resolution and sensitivity, allowing for more detailed and accurate observations. Disadvantages include the cost and maintenance of multiple telescopes, as well as the need for specialized knowledge to operate each type effectively. Additionally, using different telescopes can lead to inconsistencies in data collection and analysis.
What radiation should astronomers observe if they want to get images twenty four hours a day quickly and cheaply Why?
Astronomers should observe radio waves if they want to capture images twenty-four hours a day quickly and cheaply. Radio waves can penetrate clouds and atmospheric disturbances, allowing for continuous observations regardless of weather conditions or time of day. Additionally, radio telescopes require less complex technology and can be built at a lower cost compared to optical telescopes, making them a practical choice for frequent imaging.
What do astronomers use to measure stars?
Their eyes, Refracting Telescopes (ones with class lenses) Reflecting Telescopes (ones with mirrors) Radio Telescopes Imaging computer chips in conjunction with telescopes Space based telescopes Underground telescopes (to detect high energy or exotic particles from stars) Gravity wave detectors
What is the orgin for the word telescope?
Telescopes have been around since 1608, and they have been called "telescopes" the entire time. There is no original word.
