Telescopes
A telescope is a device used to form images of distant objects. There are two kinds: an optical telescope uses lenses and is known as a refracting telescope or a refractor, and a reflecting telescope, which uses a mirror and is known as a reflecting telescope or a reflector. The earliest telescope was a refractor built by the Dutch eyeglass maker Hans Lippershey. This category is for questions related to telescopes, including using them to view distant planets and objects in space.

Why can the star Sirius be seen without a telescope?
Sirius is one of the brightest stars in the sky, so its proximity and brightness make it visible to the naked eye. Additionally, its location in the northern hemisphere allows it to be seen throughout the year, further enhancing its visibility without the aid of a telescope.
Will You Go Blind If You Look At Planet Venus through a telescope?
No, looking at Venus through a telescope will not make you go blind. It is safe to observe Venus using proper eye protection and following safe viewing practices similar to observing the sun.
Where can you get a telescope on HorseIsle?
Treeton General Store sells them for $12,500
Treeton doesn't sell Telescopes.
Shellton - (~) Telescope $12,500
Tropicton - (~) Telescope $13,000
Yes, professional astronomical telescopes typically have greater magnification capabilities compared to telescopes sold in stores. This allows astronomers to observe celestial objects with greater detail and clarity. Professional telescopes also have larger apertures and specialized optics to gather more light and enhance image quality.
Does a reflecting telescope gather light with a lens or a mirror?
A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
When was the first telescope used in Arecibo Puerto Rico?
The first telescope used in Arecibo, Puerto Rico was the Arecibo Ionospheric Observatory, which began operation in November 1963. This telescope was originally built for ionospheric and radio astronomy research.
Large mirrors can now be made thinner and lighter than before.
Tracking celestial objects today is computer controlled and can take advantage of simpler, stronger mounts. High-speed computing today can be used to reduce the effect of Earth's atmosphere.
What problem does an earth - based telescope have that a space - baced telescope does not have?
An earth-based telescope has to contend with atmospheric turbulence, which can distort and blur images. This is not a concern for a space-based telescope, which operates above Earth's atmosphere and can provide clearer images.
Is Sarah Mather inventor of the submarine telescope African American?
Yes, Sarah Mather, an African American, is credited as the inventor of the submarine telescope. She patented this invention in 1845, which allowed for underwater exploration and observation without the need to surface.
Why do larger gasses such as neon produce more color bands than smaller gasses like hydrogen?
Larger gases like neon have more energy levels available for electrons to transition between, resulting in more color bands in their emission spectrum. In contrast, smaller gases like hydrogen have fewer energy levels, leading to fewer distinct color bands.
What telescope with 2 lenses called?
A refracting telescope uses lenses. The primary objective is the larger lens and the first point of light refraction. A smaller, secondary lens is located between the primary lens and the eyepiece as acts as another refraction device to correct or reverse the refractive aberration of the primary.
Why does the hubble space telescope orbit in the exosphere and not closer to earth?
To zoom VERY far in on certain objects in space (ones that people at NASA instruct it to look at) and takes high quality pictures for us to study and learn from so we can understand more about our universe. Google "Hubble Pictures" online and see just some of the beautiful and high-quality pictures Hubble has taken. It is also in space because, if observed from the Earth's surface, the atmosphere would interfere with the way we perceive the outer universe.
What numbers do you use on the telescope poptropica?
In the game Poptropica, the numbers used on the telescope are randomized for each player. There is no specific set of numbers to use, so you will need to find the correct combination by trial and error while exploring the telescope on the island where it is featured.
When can Ground-based radio telescopes can collect data from distant objects in space?
Ground-based radio telescopes can collect data from distant objects in space when the objects are within view of the telescope and the telescope is not obstructed by the Earth's atmosphere or interference from human-made radio signals. They are most effective at collecting data during clear weather conditions and at night when radio frequency interference is minimized.
Why do observatories have dome that can opened and turned?
Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes.
Who is the hubble telescopes was launched from space shuttle discovery?
The Hubble Space Telescope was launched from the space shuttle Discovery on April 24, 1990. The mission was designated STS-31.
What does the hubble space telescope tell us?
The Hubble Space Telescope provides valuable insights into the universe by capturing high-resolution images of celestial objects like planets, stars, and galaxies. It helps astronomers study the origins of the universe, track the movement of celestial bodies, and explore the evolution of galaxies. Additionally, Hubble facilitates the discovery and observation of astronomical phenomena, deepening our understanding of the cosmos.
What asteroid can be seen without a telescope?
4 Vesta has, at its brightest, a visual magnitude of about 5.1. This is visible to the naked eye under good seeing conditions, if you know exactly where to look.
2 Pallas at its brightest is a little brighter than 6.5, which makes it maybe visible to people with very goodeyesight under exceptional seeing conditions.
What can you see on the moon with no telescope?
Without a telescope, you can see the different phases of the moon, lunar craters, and dark patches known as lunar seas or maria. You may also see some of the moon's prominent features, such as the Tycho crater or the Apennine Mountains.
Which type of telescope detects radiation?
Because different objects give out electromagnetic radiation at different frequencies. Some objects are very easily viewed in the visible spectrum, others are essentially invisible in that spectrum. Also, some types of electromagnetic radiation can more easily penetrate dust and other debris between the source and Earth. Visible light is very easily blocked by dust, but x-rays for example can pass through them pretty much intact.
What is the telescope cordinents on poptropica?
The numbers for the coordinates are located on her thing she puts notes on [above the telescope]. You jump from thumbtack to thumbtack to find the coordinates!
[Sorry if this does not help, but I'm pretty sure that is where the coordinates for the school are located]
Did they have telescopes 100 years ago?
The planet Neptune was discovered by using a large telescope, in 1846.
That was 167 years ago.
Galileo, using a small telescope, discovered the first 4 moons of Jupiter in 1610.
That was 403 years ago. (Since then, 63 more have been discovered.)
What type of lens is used in the eyepiece for reflecting telescopes?
A radio telescope is a reflecting telescope, and uses a mirror rather than a lens.
Since radio waves are so much longer than light waves, the 'mirror' of a radio
telescope is the 'dish' reflector that focuses radio waves onto its antenna,
located at the prime focus of the dish.
Can Pluto been seen with a telescope at night?
No, it is 3,627,000,000 miles from Earth. Now that may not be far in comparision with stars and such, but because it is so tiny, and also not in the near vicinity of a bright object (and does not itself generate light) that makes it invisible to the naked eye.
How many discoveries did the Kepler space telescope make?
None. It's only a machine, that's been used by controllers on the ground to collect
various kinds of data, from which students and professional people in many scientific
specialties have extracted tentative conclusions that imply previously unknown facts.
