What else can I help you with?
How do astronomers abtain most of their information about space?
We use telescopes or satellites
What is better Reflecting or refracting telescopes?
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
Most optical telescopes used by professional astronomers are in?
Most optical telescopes used by professional astronomers are located on mountains or remote locations away from city lights to minimize light pollution and atmospheric disturbances. Some observatories, such as those in Chile and Hawaii, are known for having excellent observing conditions due to high altitudes and clear skies. Telescopes are also placed in space, like the Hubble Space Telescope, to avoid atmospheric interference.
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.
Why are most modern telescopes reflecting telescopes?
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
Most optical telescopes used by professional astronauts are housed in what?
observeries?
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
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 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.
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).
Why are most large telescope reflecting telescope?
They are much shorter than refracting telescopes, hence, much cheaper to buy and easier to transport.
Most telescopes are telescopes?
refracting
