Telescopes

The Hubble Space Telescope is located above Earth's atmosphere, which eliminates the distortion caused by atmospheric turbulence. This allows for sharper and clearer images with higher resolution compared to ground-based telescopes. Additionally, Hubble can observe wavelengths of light that are blocked by the atmosphere, providing a more comprehensive view of the universe.

Yes, it is actually nicknamed "the amateur's planet" by many sky watchers, because it is so easily viewed by common telescopes.

The attraction or repulsion that unlike or like charges have is due to the electrostatic force. Like charges (positive-positive or negative-negative) repel each other, while unlike charges (positive-negative) attract each other. This force is governed by Coulomb's law and is responsible for the interactions between charged particles.

A telescope is an optical instrument used to observe distant objects by collecting and focusing light, while a satellite is a man-made object placed into orbit around Earth or other celestial bodies for various purposes like communication, navigation, and scientific research. Telescopes can be on Earth or in space, while satellites are typically spacecraft launched into orbit.

The main difference between a telescope and a satellite is their location and function. Telescopes are ground-based instruments that observe objects in space from Earth, while satellites are man-made objects that orbit Earth or other celestial bodies to perform various tasks such as communication, weather monitoring, or Earth observation. Telescopes are used for observing distant objects in space, while satellites are used for a wide range of applications beyond just observing space.

Galileo improved the telescope in 1609, by making it more powerful and using it to observe celestial bodies such as the Moon, stars, and planets. His discoveries helped revolutionize our understanding of the cosmos and laid the foundation for modern astronomy.

There are at least two reasons why identical radio telescopes may be built. A mundane reason would to save money by reusing the same design. But the reason why most identical systems are built (not to say that saving money by reusing the design isn't still a factor in these cases) is to construct a "very long baseline interferometer", a type of multiple telescope system that uses properties of electromagnetic radiation (wave interference) to simulate telescopes with much larger apertures. This method attains the angular resolution of the larger telescope, but not the signal sensitivity.

Larger in diameter. The human eye can open to a maximum of about 7mm. Calculate the area of that, and compare it with a 50 diamter mm lens. (A=pi*r^2). Where 3.5 = radius of the pupil and: 25 = radius of the lens pi * 3.5^2 mm = 21.99 mm ^2 (area of a pupil in the dark) pi* 25^2mm = 1963.5 mm^2

Therefore, a 50 mm lens would have 89.29 more light grasp than the eye.

Plane mirrors don't form real images. Concave mirrors and convex lenses do.

Without a real image, you have nothing to expose film to, nothing to project

onto a screen, nothing to capture on a CCD or vidicon, and nothing to look at

with an eyepiece.

The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.

Thin mirrors distort images less and have a lesser weight. If the mirror isn't very thin, you can expect your image to be distorted and it can take longer to acheive the image you want or need.

During a clear night, as heat absorbed by the earth during the day seeps out, the atmosphere allows the heat to pass through. During a cloudy night, however, the clouds catch and retain the heat in the atmosphere.
Clouds trap heat being reflected from the earth
The heat radiation lost from the earth gets reflected by the clouds back to the earth, warming it. Whereas on a clear night it just escapes into space.

This could be caused by a number of issues. Beginning with the simplest, there could be an optical blockage somewhere, either in the form of a lens cap or a non refracting object between your target and your eye, Since the 114 is a reflecting telescope, there may be an issue with the mirror's collimation. This would make it difficult to focus on anything and induce coma on your targets. Simple google Collimating A Reflecting Telescope to learn how to fix this. Finally, you could have an inferior eyepiece that is plagued with few coatings and many aberrations. This would present a rather fuzzy and clouded image. Make sure to check all optics for anything that may need to be cleaned and adjusted, especially if you just bought it.

The queen in question here was Queen Cassiopeia, the wife of King Cepheus. She was considerably beautiful and vainly proclaimed it. The constellation by that name appears as a W which is taken to represent her crown. The constellation is visible all year round in the northern hemisphere night sky and is located roughly on the opposite side of the Pole Star from the Great Bear.

Reflecting telescopes use concave mirrors to gather and focus light to form an image. The primary mirror in a reflecting telescope collects incoming light and reflects it to a secondary mirror, which then directs the light to the eyepiece or camera for viewing. This design is commonly used in telescopes like Newtonian reflectors and Cassegrain telescopes.

Galileo's telescope designs using lenses were examples of early optical technology advancements that allowed for magnification and enhanced observational capabilities. These designs revolutionized astronomy and helped Galileo make significant discoveries, such as the moons of Jupiter and the phases of Venus, that supported the heliocentric model of the solar system.

Adaptive optics technology can enable ground-based telescopes to achieve images as sharp as those from the Hubble Space Telescope. This technology involves using mirrors that can change shape to compensate for the distortions caused by Earth's atmosphere, allowing for clearer and more detailed images.

It splits in differents colors according to their different wave length. An example of refracted light is a rainbow.

The ray is split in 7 colors: red, orange, yellow, green, blue, indigo and violet.

Lens openings are called apertures. They regulate the amount of light that enters the camera lens to control exposure and depth of field in a photograph. The size of the aperture is measured in f-stops.

Not directly, but knowledge of what is observed, or of the fact of observation, frequently causes people to change their behaviors and attitudes. The telescope itself doesn't affect you at all, but if you knew that other people were watching you, THAT KNOWLEDGE would affect you.

Grote Reber, not Grote Weber, is credited with building the first radio telescope in 1937. He used a parabolic antenna to observe radio waves from outer space, laying the foundation for modern radio astronomy.

Reflecting telescopes use mirrors to gather and focus light, while refracting telescopes use lenses. Reflecting telescopes tend to be more compact and easier to support larger apertures, making them popular for professional astronomical research. Additionally, reflecting telescopes are less affected by chromatic aberration compared to refracting telescopes.

A magic telescope is a tool or device, often a fictional or fantasy object, that allows a person to see things that are not normally visible with the naked eye. It is a common motif in literature and folklore, symbolizing the ability to gain insight or knowledge beyond ordinary perception.

Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
