The objective lens of a refracting telescope needs to gather as much light as possible to see faint objects in the night sky, so a larger lens helps achieve this. In contrast, the objective lens of a compound microscope is designed to magnify specimens that are already well-lit, so a smaller lens can be used effectively.

The telescope was first used by the Italian astronomer Galileo Galilei in 1609. Galileo made significant observations of celestial bodies such as the moon, Jupiter, and Venus using his telescope, which played a crucial role in revolutionizing our understanding of the universe.

Contrary to the namesake, nobody really "invented" the James Webb Space Telescope. It began as a NASA project for simply, a successor to the aging Hubble Space Telescope and the Spitzer Space Telescope (Which is an infrared telescope). It is now a collaborative project between 17 different countries, including the Canadian Space Agency and the European Space Agency. Originally, it was named the Next Generation Telescope, however later on, in 2002, it was renamed the James Webb Space Telescope in remembrance of the NASA administrator, James Webb, who played a crucial role in the Apollo missions.

The closest person to an inventor of the JWST would be the current lead project scientist, John Mather and the staff at NASA's Goddard Space Flight Center in Maryland. However, technically everyone who contributed to the JWST since 1996 could be considered co-inventors as the JWST is equipped with many different instruments purpose-built for the project.

Yes, sunspots can be seen from Earth without a telescope if viewed with proper eye protection during a solar eclipse or by using solar viewing glasses during a transit of the Sun. However, for regular observation, a telescope with a solar filter is recommended to safely observe and study sunspots.

It says 1.2 billion in this website but i'm not so sure........

Space exploration paved the way for the development of the James Webb Space Telescope by providing valuable experience in building and operating space-based observatories. Technologies and techniques developed for previous missions, such as the Hubble Space Telescope, have been applied to the design and construction of the James Webb Space Telescope. Additionally, insights gained from exploring our solar system and beyond have informed the science goals and objectives of the James Webb Space Telescope.

A parabolic mirror is the device that helps correct coma in reflector telescopes. Coma is an optical aberration that causes stars to appear distorted around the edges of the field of view. A parabolic mirror is designed to minimize this distortion and produce sharper images.

No, he did not. But his theories are supported by some interesting observations that are indirectly related to telescope technology. Under special circumstances, like the occurance of a total solar eclipse, it can be shown that the light from stars that are behind the sun actually bends under the influence of the sun's gravity, and the stars can be seen from earth. Also, very large objects in distant space like super giant galaxies can have a similar effect on objects behind them, almost as if the farther objects are being seen through a gravity telescope. So Einstein's idea that light is influenced by gravity is well established.

Telescopes use lenses or mirrors to collect and focus light from distant objects. The lenses or mirrors help to magnify the light and form an image that can be viewed by the observer.

Deserts have low humidity and minimal precipitation, which can provide clear and stable skies for observing the stars. Additionally, deserts typically have minimal light pollution, making them ideal for astronomical observations. The dry air in deserts also helps to reduce atmospheric distortion, allowing for clearer images of celestial objects.

An astronomer uses telescopes to study space. They observe celestial objects like stars, planets, galaxies, and other phenomena to understand the universe's properties and behavior.

The Hubble Space Telescope primarily uses ultraviolet, visible, and near-infrared light to capture images of celestial objects. These wavelengths are ideal for observing astronomical phenomena such as stars, planets, and galaxies.

The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.

A system of pulleys along a long carbon nanotube structure that reachs into space. There is a common misconception that there is not gravity in space, however this is not the case. Classified as microgravity it is still possible for basically anything that functions normally on earth to function normally in the microgravity of space.

Yes, right ascension is typically measured in hours, minutes, and seconds. It is one of the coordinates used in the equatorial coordinate system to locate objects in the sky.

Microscopes use lenses and light to magnify and visualize tiny objects, allowing us to see details at the cellular and molecular level. Telescopes use mirrors or lenses to collect and focus light from distant objects, allowing us to observe and study celestial bodies like planets, stars, and galaxies. Both instruments rely on the principles of optics to enhance our ability to see and study things that are not visible to the naked eye.

William Herschel's famous 40-foot telescope (also known as the "Great Forty-Foot Telescope") was 40 feet long with a focal length of 40 feet as well. It was the largest telescope in the world at that time and was used by Herschel to make important astronomical discoveries.

The famous telescope that orbits the Earth is the Hubble Space Telescope, which is a space-based observatory launched by NASA in 1990. It observes in visible, ultraviolet, and near-infrared wavelengths and has provided significant contributions to our understanding of the universe.

Galileo first invented what is recognized as the telescope.

Actually, there are at least three types. Refractor: A series of lenses, the classic "spy glass" style, carried to the extreme. Then there is the Reflector: Invented by Isaac Newton, uses a large mirror ground to a parabolic curve, and focused at the eyepiece. Lastly there is the various designs of catadioptric telescope, the most common being called the "Schmidt-Cassegrain". They use a series of different mirrors and an eyepiece to try and strike the balance between refractors (small field, large image, but dull and fuzzy), and reflectors (large field, small image, but sharp and clear). They give excellent results, but are far and away the most expensive type for the amateur. The mounting of a telescope is almost as important as the type. Simplest, most common, and least expensive is the alt-azimuth mount, but it has a half-dozen built-in frustrations. The equatorial mount is fussier to set up, requires more "homework" to use, but is much more satisfying in the long run.

Scientists typically use optical telescopes to observe and study celestial objects and phenomena in the universe. These telescopes gather and focus light to create detailed images of distant objects, helping scientists to learn more about the universe.

When an object is in space, it is usually acted upon by some form of gravitational force from a large body of which keeps it some form of orbit. In addition to this, Newton's Laws pretty much state "things like to keep doing what they're doing". Space junk has no friction acting upon it to slow it's motion, so will continue to move in an orbital motion around some body in space, and not be pulled back down to say, Earth, because of balanced centripetal forces and whatnot. (Standard stop before the physics gets silly.)

A probe can physically visit celestial bodies to conduct scientific measurements and collect data up close, whereas a telescope can only observe objects from a distance. Probes can provide more detailed and direct information about planetary characteristics, such as composition, atmosphere, and surface features. Telescopes are more limited in their ability to gather detailed data compared to probes.

There are two very similar 10-meter telescopes at the W.M. Keck Observatory on Mauna Kea, on the Big Island of Hawaii.
