Telescopes

The James Webb Space Telescope will be located approximately 1.5 million kilometers (about 932,000 miles) away from Earth at the second Lagrange point (L2), which is a stable gravitational point in space.

A telescope gathers light from objects in space, allowing astronomers to observe and study the objects in detail. This collected light is then magnified and analyzed to provide information on the object's characteristics such as size, composition, distance, and movement.

Telescopes are used by astronomers to collect light from celestial objects such as stars, planets, and galaxies. They enable astronomers to study these objects in detail, revealing information about their properties, composition, and motion. Telescopes can also help astronomers in detecting and studying phenomena like supernovae, black holes, and exoplanets.

Space boots are necessary in space to protect astronauts from extreme temperature changes, provide traction in microgravity environments, and shield them from sharp objects or debris that could pose a hazard. They also help regulate blood flow and reduce the risk of injury during spacewalks and other extravehicular activities.

Some names of unmanned missions include Voyager, Curiosity, Juno, and Hubble. These missions have explored distant planets, comets, asteroids, and galaxies, providing valuable information about the universe.

The magnification. What really matters about a telescope, the single most important piece of information, is the diameter of the main lens, or main mirror.

The largest visible light telescopes are now all ground-based, such as the Keck Observatory in Hawaii or the Very Large Telescope in Chile. These telescopes provide high-resolution images and data of celestial objects in visible light.

It refracts (bends) light into a focal point

The Pole Star appears stationary in the night sky because it lies almost directly above the Earth's North Pole. As the Earth rotates on its axis, the North Pole always points in the same direction towards the Pole Star. This makes the Pole Star visible every night, regardless of the Earth's revolution around the Sun.

Radio telescopes are used by astronomers to study celestial objects and phenomena in the radio frequency range. They are employed to detect radio waves emitted by objects such as stars, galaxies, and cosmic microwave background radiation. Radio telescopes are also used in radio astronomy research to investigate the structure and composition of the universe.

A reflecting telescope only needs one mirror, the primary mirror which will focus incoming light to a single point.

A digital telescope might place the digital recording media directly in front of the reflecting telescope without any additional mirrors (although perhaps some lenses).

For practical purposes though, most optical telescope will have a secondary mirror that will either focus light straight back through a hole in the primary telescope mirror, or to the side of the telescope.

Some telescopes, especially the large ones in observatories will have several mirrors directing the light path to the observer or recording equipment.

The light-gathering power of an objective lens or mirror is proportional to its area, or equivalently,
to the square of its linear dimensions (radius, diameter, circumference).

If the focal ratios ('f' number) are the same, then the 1-m scope scoops up 102 = 100 times as much light
as the 10-cm job.

100 times difference in brightness is exactly the mathematical definition of six (6) magnitudes brighter/dimmer.

It sounds like you have a passion for astronomy, which can be a fulfilling hobby or even a potential career path. Studying the night sky with telescopes allows for exploring the vast universe beyond our planet and can lead to discovering new celestial objects and phenomena. Consider joining an astronomy club or pursuing formal education in astronomy to further enhance your interest and knowledge in this field.

Technically, you can see every planet right up to Pluto (Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune). The last two are of course much tougher to find, since they aren't visible to the naked eye. The other 5 planets can be seen with the eye, so you will obviously be able to see them magnified slightly. If you bought a decently cheap telescope, you SHOULD be able to see Jupiter's Satellite system (the Gallilean moons) and Saturn's rings. Mars is pretty boring in tiny telescopes, and Venus displays some detail.

The Space Shuttle Endeavour was used to repair the Hubble Space Telescope in 1993 during the STS-61 mission. The crew installed corrective optics to fix the telescope's flawed vision.

Galileo Galilei is credited with being the first to use a telescope to study the heavens systematically in the early 17th century. His observations of celestial bodies through the telescope led to significant discoveries in astronomy.

The small telescope on top of a larger telescope is called a guide scope or finder scope. It is used to help the astronomer point the main telescope at specific objects in the sky by providing a wider field of view for initial alignment. The guide scope is usually equipped with a crosshair reticle for precise targeting.

The telescope was invented to allow astronomers to view distant objects in space more clearly. It revolutionized the field of astronomy by enabling scientists to observe celestial bodies such as stars, planets, and galaxies in more detail, leading to numerous discoveries and advancements in our understanding of the universe.

The use of a two lens telescope is credited to three people of Netherlands , Hans Lippershey and Zacharias Janssen, and Jacob Metius . Galileo improved on their designs and is generally given the credit of inventing the telescope.
Robert Hooke was the first to use a two lens microscope.

A group of scientists decided to name space "space" because they saw how empty it is and how much space there is in what we now know as "space".

The telescope has allowed man kind to study the universe more in depth and accurately than possible with the naked eye. It helps map out the stars, planets, moons, and whole galaxies. You wouldn't want to pull a Lewis and Clark around the galaxy would you?

Most telescopes collect and focus light from distant objects in space, such as stars, planets, and galaxies. This focused light is then magnified and analyzed by astronomers to study and make observations about the universe.

That depends on what you are looking at. Reflectors are great for looking at galaxies close up and are usually cheaper. Refractors are better for seeing color in objects, however some brightness is lost as a result of the two-way mirror the light has to pass through.

The telescope on Panfu is located at the Mystic Garden. It can be found on a platform near the waterfall.
