Most optical telescopes used by professional astronauts are housed in what?
observeries?
What of the three properties in optical telescopes is most important?
The most important property of optical telescopes is their aperture size, which determines the amount of light the telescope can collect. A larger aperture allows for better resolution and the ability to detect fainter objects, ultimately enhancing the telescope's ability to observe distant celestial phenomena. While other properties like focal length and optical design are also significant, the aperture is crucial for overall performance and image clarity.
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.
Why do telescopes used for astronomy not have prisms to make the image the right way up?
Because it's not important. Introducing a prism into the optical path would absorb some of the light, which is important. So the tradeoff is an easy choice for astronomers to make.
Do astronomers sleep during the day?
If they have been observing at night, yes - rather like shift workers. However most astronomers no longer observe directly but use cameras that are much more sensitive than the human eye to obtain their telescope data. This allows telescopes to be automated and the data save so that astronomers can analyse it during the day without having to visit the telescope. These astronomers work normal hours and only a few are needed to man the telescopes (a task which may also be done remotely).

How do astronomers abtain most of their information about space?
We use telescopes or satellites
What type of telescope is most often used to view distant objects?
Reflecting telescopes are far-and-away the most common. This is because the telescope can be smaller and lighter, and because lenses always absorb a little light while mirrors can be almost perfect reflectors.
What year was the non optical telescope invented?
The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
Can even the most powerful telescopes see through Venus' clouds?
Optical telescopes can't penetrate the clouds of Venus, but data have been collected from the surface and from the atmosphere below the clouds with radar, radio telescopes, and landing spacecraft.
What can radio telescopes do that optical telescopes cant?
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
Why do most professional astronomers use reflecting telescopes?
Bang for the buck. When you need to collect a lot of light to see faintcelestial objects clearly, a large mirror is cheaper and easier to manufacture without defects than asimilarly sized refracting lens.
What are Astronomer typical work schedule?
Very little astronomy is still done by physically looking through telescopes, so astronomers can basically work any hours they want. The really large telescopes are quite expensive and tend to be shared (and located in remote, desolate places). Most astronomers rely on dedicated on-site staff at the scope who collect images or data for the astronomers to analyze later.
What do astronomers do every day?
Astronomers use the principles of physics, chemistry, and mathematics to learn about the fundamental nature of the universe, including the sun, moon, planets, stars, and galaxies. As such, astronomy is sometimes considered a subfield of physics. They also apply their knowledge to solve problems in navigation, space flight, and satellite communications and to develop the instrumentation and techniques used to observe and collect astronomical data.Almost all astronomers do research. Most of them also have teaching as part of their work, usually in a university.Some are theoreticians, working on the laws governing the structure and evolution of astronomical objects. Others analyze large quantities of data gathered by observatories and satellites and write scientific papers or reports on their findings. Some astronomers actually operate large space-based or ground-based telescopes, usually as part of a team. However, astronomers may spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments.A small number of astronomers work in museums housing planetariums. These astronomers develop and revise programs presented to the public and may direct planetarium operations.Work environment. Most astronomers do not encounter unusual hazards in their work. Astronomers who make observations with ground-based telescopes may spend many hours working in observatories. This work usually involves travel to remote locations and may require working at night. Astronomers whose work depends on grant money may spend a lot of time writing grant proposals to keep their work funded.Astronomers may need to work at odd hours to observe celestial phenomena, particularly those working with ground-based telescopes.
What type of scientist studies the Solar System stars and galaxies?
Collectively they are called Astronomers and Astrophysicists. Either professionals or amateurs.There are many types of astronomers, defined by how they study the stars. The most well-known are those that use optical telescopes followed closely by those that use Radio-telescope to pick up wavelengths other than visible light. there are many others and many other ways to collect data on the galaxies and stars.Astrophysicists are astronomers and may also collect direct data, yet they are more interested in the working behind the data. They deal in physics and theories of the galaxies.
