Telescopes

The telescope was invented first in 1608. If you want to know more about the telescope see related links below.
Though there is some conflict over who, exactly, invented the first telescope, the earliest working models seem to have been invented by Hans Lippershy in 1608. Just a year later, Galileo was using these devices to do incredible research, helping him discover that the sun was rotating-- fully convincing them that the Heavens were governed by predictible movement, leading to his later assertion that the Earth moves around the sun. This timely invention played a vital part in our intellectual history.
Galileo built a 20 power telescope, the first telescope capable of being used for astronomy, in 1609.

With current technology, it is not possible to see specific manmade objects on the Moon from Earth. The Apollo landing sites and other artificial structures are too small to be resolved by even the most powerful telescopes.

Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.

A telescope can help you observe unidentified flying objects (UFOs) if they are within its range and visibility. However, the telescope's purpose is to magnify and enhance the image of distant objects, so it may not provide definitive proof of the UFO's nature. It could help you gather more details about the object's characteristics.

Visible Light telescopes use mirrors or lenses. The images are viewed by the naked eye. Telescopes operating in invisible wavelengths use Electromagnetic sensors. The data is then converted into an image that can be viewed by us.

Yes, there are still Henry Fitz telescopes in use in the US. These telescopes are popular among amateur astronomers for their ease of use and affordability. Although they are no longer manufactured, many existing Henry Fitz telescopes are still being used for stargazing and observing celestial objects.

How about a few? Absorption of light through the lens(es). Chromatic aberation, requiring, preferably, a multiple lens like an achromatic or apochromatic lens which increases absorption. Reflection of light off of the objective lens. Maximum exposure to the elements, causing fogging. Maximum diameter of about 40 inches due to gravity. Difficulty of making at least four optical surfaces to reduce chromatiic aberation (and, these must stay aligned for the life of the telescope). Enough?

The equatorial mount allows one axis of the telescope to be parallel to the Earth's axis. This allows you to track an object by only changing one axis. This axis is Right Ascension. The other axis is Declination.

The planet Mars, often referred to as the "Red Planet," exhibits a reddish appearance due to iron oxide (rust) on its surface. The dark regions are volcanic plains and dark sand dunes, with the darker regions changing intensity as they are influenced by seasonal changes in temperature and wind patterns.

Yes, reflecting telescopes are popular among astronomers and amateur stargazers due to their simple design, large aperture size, and ability to provide clear and detailed views of celestial objects. They are widely used in research observatories and are also common in backyard astronomy setups.

october 4th 1975 the telescope was invented and the event officialy began the space age because of the launch of the first satillite by USSR

Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses. Reflecting telescopes typically have a closed tube design which protects the mirrors from dust and other contaminants, while refracting telescopes are more prone to chromatic aberration. Reflecting telescopes are generally easier to manufacture at larger sizes compared to refracting telescopes.

Yes, the Hubble Space Telescope is capable of taking pictures of Mercury. However, since Mercury orbits close to the Sun, special considerations must be taken to avoid damaging the telescope's sensitive instruments. Additionally, images of Mercury taken by Hubble may not be as detailed as those captured by spacecraft specifically sent to study the planet.

it is becaus water molecules absorb infrared wavelengths. By being placed at the top of a mountain, it will be above the clouds meaning there is less moisture in the air to disrupt the signal.

The eyepiece of a reflecting telescope typically contains a convex lens. This lens helps magnify the focused light that has been reflected off the primary mirror, allowing the observer to see a magnified image of the object being observed.

The term "radio telescope" is used because it specifically refers to a type of telescope that is designed to detect radio frequencies emitted by celestial objects. The term "radioscope" may cause confusion as it could be interpreted as a device that visualizes radiation in general, not specifically radio waves.

The first telescope is commonly attributed to Hans Lippershey, a Dutch eyeglass maker, who is believed to have applied for a patent for a refracting telescope in 1608. Galileo Galilei made significant improvements to the design shortly after, leading to his astronomical discoveries.

1. Visible light: Telescopes collect photons in the visible light spectrum to observe celestial objects.
2. Infrared radiation: Telescopes sensitive to infrared radiation detect heat emitted by objects in space that are not visible in the visible light spectrum.
3. Radio waves: Radio telescopes capture radio waves emitted by astronomical sources, providing valuable information about the universe.

There are thousands of observatories in the world, ranging from small amateur setups to large professional facilities. The exact number can vary as new observatories are built and existing ones are decommissioned.

The Hale Telescope is a 5-m reflecting telescope at the Palomar Observatory. Some factors that limit its ability to collect starlight are light pollution, turbulence in the atmosphere, daylight and clouds.

A telescope that uses one or more mirrors is called a reflecting telescope. Light is collected and focused by the primary mirror, which then reflects it to a secondary mirror that directs it to the eyepiece or detector. This design allows for larger apertures and better image quality compared to refracting telescopes.

The reason we locate optical telescopes in high places is because the earth's atmosphere distorts the light that passes through it. If we can get higher up, there will be less atmospheric distortion of the light from the objects we're observing. Additionally, there is usually less light pollution to affect the images, but relief from atmospheric distortion is the primary reason we go up.

Mirrors reflect light. A mirror's smooth surface allows light to bounce off of it in a predictable manner, resulting in a clear reflection of an object. Refraction of light occurs when light passes through a transparent material and changes speed, causing the light to bend.

The most chromatic aberration would occur with a single-lens refractor. However, today most telescopes employ at least two lenses, called achromats. These still incur significant chromatic aberration if the telescope has a short focal length to aperture ratio, called focal ratio. An easy way to determine if the telescope will have significant chromatic aberration is to divide the focal ratio of the telescope by the diameter of the lens in inches. A value of 5 or higher indicates minimal chromatic aberration; 3 to 5 is moderate aberration, and 3 and under is significant chromatic aberration. However, chromatic aberration is generally only obvious on bright stars or planets.
