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).
What do astronomers do?
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 advantages do reflecting telescopes have over refracting telescopes?
refracting telescopes use lenses instead of mirrors. 1. chromatic aberration: when light passes through a lens it is focused at different points. Blue focuses closer to lens and red farther creating a smeared image. 2. Some light is absorbed by lenses. 3. Lenses are heavy and can only be supported by the edge. 4. Lenses must have to optically acceptable surfaces whereas a mirror only needs one.
What uses a mirror to focus light from the object being viewed?
Reflecting telescopes are designed to have a curved lens which allows for objects further away to be seen clearer. For this reason astronomers and other individuals that study outer space use reflecting telescopes.
What are the two ways of astronomers?
Astronomy is the overall title for a variety of sciences that involve the study of space and that outside of our planet. Some types of it as Astrophysics, Exobiology, Planetary or Exo Planetary astronomy, and Radio Astronomy just to name a few. Astronomy has many parts, such as planets, stars, black holes, star clusters, etc. They all have to do with space.

Can mirrors cameras telescope and eye glasses refract light?
Mirrors don't refract, they reflect. All lenses, on the other hand, refract (bend) the light. All cameras have lenses, to focus the image; same for eyeglasses. Some telescopes have lenses, but others are collections of mirrors. Note that some few optical elements are lenses and mirrors - like prescription sunglasses with mirror coating.
Are astronauts and astronomers the same?
As astronaut travels into outer space and some have been killed doing so. Most astronomers stay on the planet Earth and look up into space. There have been astronauts who are astronomers, but, most astronomers are not astronauts. There have been tens of millions of astronomers looking up at outer space, but, only a few hundred astronauts. No, they are not the same.

What type of scientist study stars and planets?
astronomers!!!!! There are many different fields withing research into space all with specific names and job roles. Some include: Cosmologists Astronomers Plantologists "Space Scientist" Various engineering roles connected with space missions just to name a few :/
Where can a person go to purchase telescopes for kids?
Telescopes for kids can be bought at the websites ToysRUs, Telescope and ScopeShops to name a few. The website Telescope sticks out, as it is easy to understand and they also provide a decent range of beginner telescopes.
What is the type of camera lens which enlarges distant images?
Camera lenses that enlarge distant images are normally known as long focus lenses or telephoto lenses. A few specialist lenses use mirrors as well as glass and are frequently referred to as mirror lenses.
Why are most large telescopes reflectors and not refractors?
Most large telescopes are reflectors because they can be made with larger apertures and are less affected by chromatic aberration compared to refractors. Reflectors also allow for easier mounting of additional instruments and have better light-gathering capabilities.
Where can Focus contact lenses be bought?
Focus contact lenses can be purchased from many companies on the internet. A few of the companies that sell Focus contact lenses include but not limited to, VisionDirect, GetLenses, and WeLoveLenses.
What instruments make use of lenses?
We find that imaging equipment that makes tiny things appear big (a microscope) or really far away things appear close (a telescope) uses lenses. There are also new tools that allow looking "into" and "around" things by virtue of fiber optics, and they employ lenses. Industry and medicine have a wide variety of 'scopes to do all kinds of stuff with. Still and moving picture technology still relies on lenses. There are a few more things, lke a simple looking glass, that are or make use of lenses. Oh, and don't forget corrective optics so people can see better. Glasses or contacts are lenses.
Which astronomers who found few natural satellites for Saturn?
Giovanni Domenico Cassini and Christiaan Huygen
