Telescope, device used
to form magnified images of distant objects
. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
How does the telescope help us today?
Telescopes have also helped us
understand gravity and other fundamental laws
of the physical world. … Some new telescopes allow us to study objects in the universe by detecting the heat or radio waves or X-rays they emit. Telescopes are now discovering planets around other stars.
Why was the invention of the telescope so important?
The invention of the telescope played an important role in
advancing our understanding of Earth’s place in the cosmos
. … Early telescopes were primarily used for making Earth-bound observations, such as surveying and military tactics.
Why do we need telescope?
Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe
. There are many different types of space telescopes. Some are used to study a special object like the Sun. Others are used to study the different types of light given off by objects in space.
Why is the telescope important for kids?
A telescope is an
important tool for astronomy that gathers light and directs it to a single point
. Some do this with curved mirrors, some with curved lenses, and some with both. Telescopes make distant things look bigger, brighter and closer.
How did the reflecting telescope changed the world?
Reflector telescopes,
because they are easier to make and can be made in sizes much
larger than refractors, are an invention that changed astronomy and our understanding of the universe. The largest refractor telescope in the world is forty inches in diameter and reflector telescopes dwarf this in comparison.
Who invented Durbin?
| Hans Lipperhey | Died September 1619 (aged 48–49) Middelburg, Dutch Republic | Nationality German, Dutch | Occupation spectacle-maker | Known for Inventor of the telescope (earliest known patent application) |

How can we maximize the purpose of telescope?
By placing an
extension tube between the Barlow lens and the eyepiece
, you will increase the magnification of a telescope by two three or more times, depending on the size of the extension tube.
What makes a telescope more powerful?
Generally, the
larger the aperture
, the more light the telescope collects and brings to focus, and the brighter the final image. The telescope’s magnification, its ability to enlarge an image, depends on the combination of lenses used. The eyepiece performs the magnification.
How do reflecting telescopes work?
Reflecting telescopes are sometimes called Newtonian telescopes after their inventor Isaac Newton who built the first one in 1668. They
use mirrors to collect and focus the light towards the eyepiece
. … They combine both lenses and mirrors to focus the light towards the eyepiece.
What are the disadvantages of telescope?
- Very high initial cost relative to reflector.
- A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
- Long focal ratios can mean that the instrument is cumbersome.
What was the first telescope?
The first record of a telescope comes from
the Netherlands in 1608
. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument “for seeing things far away as if they were nearby”.
How far can our telescopes see?
The Hubble Space Telescope can see out to a distance of
several billions of light-years
. A light-year is the distance that light travels in 1 year.
What are the two most important properties of a telescope?
- Light gathering ability – The better a telescope can gather light, the better you will be able to see far away stars and faint objects in the night sky. …
- Magnification – The magnification of a telescope describes how much larger the telescope can make objects appear.
What is the best telescope for a 6 year old?

- Emarth Refractor Telescope. …
- MaxUSee Kids Telescope. …
- Celestron Inspire 80AZ. …
- Orion StarBlast II 4.5 Equatorial Reflector Telescope. …

- Celestron 21024 FirstScope Telescope.
Which mirror is used in telescope?
The Reflecting Telescope or Reflector uses
a concave mirror
as the telescope’s Primary Objective, rather than a lens or lenses. The type of reflector depends on other system mirror(s), called the Secondary Mirror.
