Are you looking to learn more about the purpose behind using an astronomical telescope? Then this blog post is for you!
An astronomical telescope is a telescope that is designed to be used for observing solar systems outside of an earth’s atmosphere. These telescopes are always pointed at the sky and not into space; they have long and narrow tubes that allow air to flow around them as they collect light. Astronomical telescopes are typically used in field of astronomy and in planetariums.
What are the three purposes of a telescope?
The three purposes of a telescope are to view objects that are difficult to see with the naked eye, magnify distant objects, and collect data for research.
Viewing astronomical objects that are difficult to see with the naked eye
Some astronomical objects are too faint to be seen with the naked eye, but still can be observed by a telescope. This is especially true for many galaxies, nebulae and star clusters that emit little or no light, but still are visible through a well-equipped telescope.
About 90% of all galaxies can be seen by the unaided eye, but only about one percent of all galaxies can be seen through an astronomical telescope. Galaxies generally emit very little light, making it difficult for the unaided eye to see many of them.
If the light from a galaxy, for example, is blocked by the Milky Way, then even though it can still be seen through an astronomical telescope, its size and apparent shape will never be perfectly clear.
As the light pollution around most galaxies becomes worse over time as more and more cities throw their lights up into the sky, astronomers will be able to see far fewer of these galaxies in our own galactic neighborhood.
Magnify Distant Objects In Space
Magnifying distant objects in space is a practice that has been done for centuries. Galileo, for example, was one of the first to attempt this feat. His early attempts didn’t work because he didn’t have a telescope with an objective lens and a focal length that worked together properly. Christiaan Huygens was the first to figure out how to do this, making Galileo’s later attempts more successful.
The increase in power made possible by telescopes over the past few centuries has become noticeable. Telescopes available today have magnifying ability of up to 60 times, while the older ones of Galileo’s day were only able to magnify objects up to 20 times their normal size.
This change in the ability to magnify distant objects in space has also come with some drawbacks, however. While these objects now appear larger, they also appear distorted due to the eyepiece’s magnification, making it difficult for astronomers to get a clear and accurate look at what they are studying.
Because of this problem, many astronomers have begun using digital cameras instead of photographic film. This allows them to view their photographs on a computer screen instead of having to wait until the film is developed before continuing their work.
Collecting Data About Space For Research
Scientists are collecting data about outer space. The different types of research, which include astronomy and astrophysics, are being used to study the universe. Astronomers use telescopes and other instruments to observe celestial objects and events. Some modern telescopes are advertised to be able to see objects as small as Saturn’s rings or the moons of Jupiter.
The Hubble Space Telescope was put in space and orbits Earth. It has been sending back photographs of outer space for years. Some telescopes are not in space, but they are also used to study and collect information about outer space.
