Telescopes

Yes, you can see the moon with a 30x telescope. A telescope with 30x magnification is powerful enough to offer a detailed view of the moon, allowing you to observe its craters, mountains, and other features. Just be sure to wait for a clear night with minimal light pollution for the best viewing experience.

Galileo Gailei is the first person credited with using the telescope for astronomical observations. He did not invent the telescope. He is the first to have seen moons going around Jupiter, the rings of Saturn (though he incorrectly identified them), and that the Moon had cliffs and craters.

Isaac Newton invented it, as he understood from his study of optics that a large lens, or mirro, gathered more light than a small one, and the objective lens of the best telescopes of the time rarely exceeded about 30mm (inch and a quarter). The principal worked, allowing him to see many more celestial bodies than the telescopes of the time, though usually with a smaller image, overall.

It depends on what you mean by teleportation. If your teleportation happens at the speed of light, then no. When you got there and looked back, you'd see what happened right after you left. If the teleportation was "instantaneous" (assuming that Earth and Point X are stationary relative to each other, an observer midway between would say that your disappearance on Earth and appearance on X were simultaneous), then yes, you'd see events on Earth that happened prior to your teleportation. How much prior depends on how far you went. Of course, you might see magic fairy unicorns, since our current understanding of relativity says those are just as real as instantaneous teleportation.

No. In fact, using a telescope would almost guarantee that you would not see any meteors. Here's why.

Telescopes magnify a small area of the sky; the more powerful the telescope, the smaller the area. Telescopes are great for getting a close-up view of things that aren't moving too quickly; even then, with a big scope, you'll be re-centering it often as the Earth turns and the star/planet/comet/whatever drifts out of view.

Meteors can appear anywhere in the sky. They come VAGUELY from the constellation Perseus (for the Perseid meteors) or from other constellations that lend their names to the specific shower. Perseids enter the Earth's atmosphere at 130,000 miles per hour; they cross the sky in a second and either burn out or explode. There is NO WAY for you to see the incoming meteor, point the scope at it, and center; it's already gone. And since you don't know where the next meteor will appear, it would be like playing the lottery to point your telescope at a spot in the sky and just HOPE that you get lucky.

In a strong meteor shower, you might see a dozen in a minute, sometimes three or four together. Keep your head buried in a telescope, and I'll offer you a wager that you'll miss the best parts of the show.

Telescopes are great. But not for meteor showers.

Still determined to use your telescope during a meteor shower? Point it at the Moon! The Moon isn't THAT far away from Earth; the Moon is in the same meteor shower that the Earth is. Astronomers studying the Moon have watched hundreds of meteor strikes on the Moon over just the last year or so. Little meteors that make a nice light show in the sky aren't big enough to punch the Moon very hard, but there are those millions of millions of craters on the Moon, and each one was caused by a BIG impactor. There's chance - a SLIM chance - that you could see the explosion of a lunar impact.

Naked eye on the sky, or use your telescope on the Moon; either way, good hunting!

= Topic 1 Lenses and Refracting Telescopes = In the exam you are expected to know about: * Principal focus, focal length of converging lens * power = 1/f * Formation of images by a converging lens * Ray diagrams * Lens formula: 1/f = 1/u + 1/v * Astronomical telescope consisting of two converging lenses * Ray diagram to show the image formation in normal adjustment * Angular magnification in normal adjustment * M = angle subtended by image at eyeangle subtended by object at unaided eye * Focal lengths of the lenses * M = fo/fe * *: Refractors were the earliest type of optical telescope. The first practical refracting telescopes appeared in the Netherlands in about 1608, and were credited to three individuals, Hans Lippershey and Zacharias Janssen, spectacle-makers in Middelburg, and Jacob Metius of Alkmaar also known as Jacob Adriaanszoon. Galileo, happening to be in Venice in about the month of May 1609, heard of the invention and constructed a much improved version of his own based on his understanding of the effects of refraction. Galileo then communicated the details of his invention to the public, and presented the instrument itself to the Doge Leonardo Donato, sitting in full council. Galileo may thus claim to have invented the refracting telescope independently, but not until he had heard that others had done so

The moon is about 0.0000000406 light years away from earth.

Clearly, the moon is MUCH too close (238,000 or 239,000 miles or so) for the distance to be rendered meaningfully in light years.

I'm not aware of any telescopes that begin with the letter "Hub." Telescopes often have names like Hubble, which is named after astronomer Edwin Hubble, or Hubbell, which may be a variation or misspelling of the Hubble Space Telescope.

a refractor or a reflector are two types of telescope.

LOMO Optics refers to lenses and mirrors produced by the LOMO company in Russia. In telescopes, LOMO Optics are known for their high-quality construction and precision, offering clear and sharp images of celestial objects. Telescopes equipped with LOMO Optics are popular among amateur astronomers for their performance and affordability.

Careers that use telescopes include astronomers, astrophysicists, planetary scientists, and aerospace engineers. Telescopes are essential tools for observing and studying celestial objects in space, such as stars, planets, and galaxies.

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.
