What else can I help you with?
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
Is this a good idea to locate a radio telescope near a radio station?
Locating a radio telescope near a radio station is generally not a good idea due to potential interference from the radio station's broadcasts. Radio telescopes are extremely sensitive to electromagnetic signals, and the noise from a nearby station could disrupt observations and data collection. Ideally, radio telescopes should be placed in remote areas with minimal man-made radio frequency interference to ensure accurate and clear readings of celestial objects.
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Group of radio telescopes radio telescope array radio astronomy?
Radio Telescope Arrays
Radio telescopes are the best way to receive enhanced radio broadcasts.?
---False
What are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
How are radio telescopes different from the keck tetescopes?
Radio telescopes and Keck telescopes differ primarily in the type of electromagnetic radiation they observe. Radio telescopes detect radio waves emitted by celestial objects, allowing astronomers to study phenomena like pulsars and cosmic microwave background radiation. In contrast, the Keck telescopes, which are optical/infrared telescopes located in Hawaii, observe visible and infrared light, enabling detailed imaging and spectroscopy of stars, galaxies, and other astronomical features. This distinction in wavelength leads to different techniques and instruments used in their respective observations.
What do astronomers use to map the shape of the Milky Way?
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
Why are radio telescopes able to operate all the time?
That is because radio waves pass through clouds so radio astronomers do not have to wait for a clear sky.
What are 3 basic categories of astronomical observation?
The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.
Used by astronomers to study stars and planets?
Astronomers use telescopes to study stars and planets by capturing light from these celestial objects and analyzing it. They can gather data on the properties of stars and planets, such as their temperature, composition, and distance from Earth, to deepen our understanding of the universe. Telescopes come in various forms, such as optical telescopes, radio telescopes, and space telescopes like the Hubble Space Telescope.
Which is the least likely to be used by astronomers to investigate galaxies?
Astronomers are least likely to use optical telescopes for investigating galaxies that are very distant or obscured by interstellar dust, as these telescopes primarily detect visible light. Instead, they often rely on radio, infrared, or X-ray telescopes, which can penetrate dust and reveal more information about such galaxies. Optical observations are still valuable, but their limitations make them less effective for certain types of galaxy studies.
What do most telescopes collect and focus?
Most telescopes collect and focus light from distant objects in space, such as stars, planets, and galaxies. This focused light is then magnified and analyzed by astronomers to study and make observations about the universe.
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.
Why are ratio telescopes instead of optical telescopes used to determine the structure of the milky way galaxy?
Ratio telescopes, often referred to as radio telescopes, are used to study the structure of the Milky Way galaxy because they can detect radio waves emitted by celestial objects, allowing for observations through interstellar dust that obscures optical wavelengths. This capability enables astronomers to map the distribution of hydrogen gas and other components of the galaxy, revealing its spiral structure and dynamics. Additionally, radio telescopes can capture data from various wavelengths, providing a more comprehensive understanding of the galaxy's morphology and behavior.
Which human sense is extended by a radio telescope?
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.
