What is the difference between a terrestrial telescope and a astronomical telescope?
The differences are typically the method of mounting the scope, and possibly
the physical presentation of the eyepiece.
-- The mounting of an astronomical instrument typically has one axis that can be set
parallel to the Earth's axis, and a motor to turn the scope around it, so as to follow
the apparent "daily motion" of sky objects. A terrestrial telescope doesn't need to
rotate parallel to the Earth's rotation, and doesn't need to be clock-driven once you
find the object you want to watch through it.
-- An astronomical telescope is usually pointed in some degree of "upward"
direction, and for comfort's sake, the optical path often includes a 90-degree
turn, so that the eyepiece comes out perpendicular to the scope's axis, and you
don't have to scrunch down behind the tube and look up. A terrestrial scope is
typically pointed more nearly horizontal, and it isn't nearly as inconvenient to
look through it in the true direction in which it's pointed toward the target.
Why can the hubble space telescope see so far into space?
The Hubble space telescope has no interfering forces and it's design enables it to capture more things also the people at NASA take a tiny sand grain size dot of the picture it took and they enlarge it which shows even more stuff!
What could have happened if telescope had not been invented?
Without the invention of the telescope, our understanding of the universe would be severely limited. Important discoveries such as galaxies, supernovae, and planets orbiting other stars would not have been possible. Astronomy and many other fields reliant on telescopic observations, such as astrophysics and cosmology, would be stunted in their progression.
How far can the telescope on mount palomar see?
The telescopes on Mount Palomar, such as the Hale Telescope, can see objects over billions of light-years away. They have been instrumental in making numerous astronomical discoveries and observations of distant galaxies, stars, and celestial phenomena.
-- Galileo saw small bodies orbiting another planet in the solar system. That
took the steam out of the story that the Earth is the center of everything.
-- Newton showed that IF his simple formula for gravity is correct, then the
planets must move according to Kepler's laws, which accurately explained
everything we actually see the planets doing in the night sky.
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it.
Lines are shifted toward shorter wavelength if the object is moving towards us.
They're shifted toward longer wavelength if the object is moving away from us.
What is a refracting device called?
A refracting device is called a lens. It is an optical device that is designed to refract light in a way that converges or diverges the light rays to create an image.
Who was the first astonomer to make extensive use of the telescope?
Galileo Galilei was the first astronomer to make extensive use of the telescope for astronomy. He made several important discoveries, such as the moons of Jupiter and the phases of Venus, using his telescope in the early 17th century.
What was the two lenses called on the refracting telescope?
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.
Which structure is used to foucus light in a refelcting telescope?
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.
Where was the Yerkes telescope made?
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.
Where is flapjacks magic telescope on toonix?
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!
What is resolution of a telescope and What physical process limits it?
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
How did newton's invention of the reflecting telescope affect the field of astronomy?
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.
What are not detected by telescopes Radio waves sound waves X rays Visible light?
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.
What is the star next to Venus?
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.
Do x ray and gamma ray telescopes have the same design as an optical instrument?
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.
Refers to a telescope's ability to make an object larger?
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.
What is the state with the largest collection of telescopes?
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.
Why would you use telescope to look at the stars instead of microscope?
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.
Why do they need to repair the Hubble space telescope?
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.
What was the launch date of the Hubble space telescope?
The Hubble Space Telescope was launched into orbit on April 24, 1990.
Can the polar caps and dust storms of Mars be seen with Earth based amateur telescopes?
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.
