Telescopes

The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.

A curved mirror is used to focus light in a reflecting telescope by reflecting and converging the light rays to a focal point. This mirror can have a concave shape to collect and concentrate light towards the eyepiece for observation.

The Yerkes Observatory, which houses the Yerkes telescope, was made in Williams Bay, Wisconsin, United States. It was designed by architect Henry Ives Cobb and completed in 1897.

Flapjack's Magic Telescope can be found in the "Snack Shack" location within the Toonix world. Keep an eye out for this iconic item as you explore the virtual world!

The resolution of a telescope is the telescope's ability to determine if two points are seen as two points or one smudgy point. Resolution, or resolving power is measured as an angle below which differentiation cannot be made.

The resolution of a telescope is a consequence of the wave nature of light. Because waves can add to each other, or cancel each other, in a process called diffraction, the aperature of the telescope must be as large as possible compared to the distance to the objects and the wavelength of the light to give the best performance. An equation which describes the resolution of a telescope is

Newton's invention of the reflecting telescope improved the quality and resolving power of telescopes, allowing astronomers to see fainter and more distant celestial objects with greater clarity. This advancement revolutionized observational astronomy and laid the foundation for future telescope designs.

It is generally more challenging to produce large mirrors for telescopes compared to large lenses because mirrors need to be ground and polished to a very high precision to avoid distortions and aberrations in the images produced. Lenses can also suffer from similar issues, but the methods to correct them are different and often less complex. Additionally, mirrors are usually easier to support and maintain their shape compared to large lenses.

Sound waves are not detected by telescopes, as telescopes are instruments that are designed to detect electromagnetic radiation, such as radio waves, X rays, and visible light. Sound waves require a medium, such as air or water, to travel through, and can't propagate through the vacuum of space where telescopes operate.

The star next to Venus is most likely the planet Jupiter. Venus and Jupiter are two of the brightest objects in the night sky and are often visible close to each other. Jupiter will appear as a bright point of light that is usually larger and not twinkling like a star.

No, x-rays and gamma rays cannot be focused by lenses or conventional telescope mirrors. To make mirrors that will focus x-rays or gamma rays you need very shallow glancing angle mirrors, that are nearly just parabolically tapered tubes. Typically several of these tubes with the same focal point but different diameter are nested inside each other.

Magnification refers to a telescope's ability to make an object appear larger when viewed through the telescope. It is the degree to which the image of the object is enlarged compared to what is seen with the naked eye.

Hawaii is the state with the largest collection of telescopes at the Maunakea Observatories, located on the Big Island. Maunakea is considered one of the best astronomical sites in the world due to its high elevation and clear skies, making it ideal for stargazing and astronomical research.

A microscope isn't used for navigating/exploring the universe. A microscope is for looking at germs, viruses etc. A telescope is able to look at the sky. A microscope is used in science labs. Not use for space explorering.

The best known Hubble repair mission was to install a fix to some flawed optics aboard the telescope. Other missions have been to replace other aging hardware and install more capable equipment for more advanced research.

The Hubble Space Telescope was launched into orbit on April 24, 1990.

Yes, the polar caps of Mars can be seen with Earth-based amateur telescopes during certain times of the year when they are not obscured by dust storms. Dust storms on Mars can also be observed with specialized equipment and are sometimes visible to amateur astronomers as changes in the planet's appearance.

The atmosphere of the Earth filters out and blocks plenty of radiation from outer space. Thus, telescopes are placed on satellites to glean information from these rays that would otherwise not be able to reach Earth-based telescopes.

Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.

1. Radio telescopes are directional radio antennae that have a curved shape and are used like other astronomical telescopes to study objects in the universe beyond Earth and the Solar System. They gather radio waves and process them by using a computer.

Yes, the Hubble Space Telescope has been repaired several times since its launch in 1990. The last servicing mission was in 2009.

The HST orbits at 569 km (353 miles) above Earth, orbits it in 97 minutes at a speed of 17,500 miles per hour (28,500 km per hour). In one second the HST travels almost 5 miles!

They are able to see further into space now and see more detail of certain objects. Before telescopes, it was all observation astronomy. Whatever you could see with your naked eye was it. Once the telescope was invented, they were able to see more detail of our night sky. Scientists were able to identify and watch celestial objects over periods of time. watching their movements

The ancient Babylonians were likely the first to observe Saturn without a telescope around 700-600 BCE. They noted its slow movement against the fixed stars.

You can't really use telescopes because there is to much glare. But if you look up at the sky, you can see stars are Blue, And red. Blue stars are large and have short life spans. Red stars are red Supergiants. Stars late in there life cycle.
