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.
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
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
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.
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.
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.
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.
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.
What tool do astronomers use to study space?
they use space probes,satellites,and of coarse,telescopes.
If Suppose astronomers are interested in obtaining an image of a large area in the sky which radiation should astronomers observe if they want to get images 24 hours a day quickly and cheaply why?
Astronomers should observe in the radio wavelengths for imaging large areas of the sky quickly and cheaply, as radio telescopes can operate continuously, day or night, regardless of weather conditions. Unlike optical telescopes, which depend on clear skies and daylight, radio waves can penetrate clouds and are not affected by light pollution. Additionally, radio observations are often less expensive in terms of equipment and operation compared to other wavelengths, making them a practical choice for large-scale sky surveys.
Radio telescopes are often connected together to do interferometry What is the primary problem overcome by radio interferometry?
The primary problem overcome by radio interferometry is the limited resolution of individual telescopes. By combining signals from multiple telescopes, interferometry creates a virtual telescope with a larger diameter, which improves the resolution and allows astronomers to see finer details in the radio sources being observed.
