Why can a Hubble space telescope make very detailed images in visible light?
I assume you mean the Hubble Space Telescope. Such space telescopes benefit from the lack of an atmosphere: there is no atmospheric distortion, which otherwise severely limits the image quality. The lack of an atmosphere also lets such telescopes see in frequencies that don't get down to Earth at all, for example infrared and ultraviolet. There are OTHER space telescopes in orbit that use this benefit to observe x-rays.
Why might two lens be used in a telescope?
Because light can enter a lens from either side, a lens has a focal point on both sides. With mirrors, on the other hand, light only enters from one side, so they only have one focal point. the apex answer:
The centers of curvature of the two sides of the lens The material the lens is made from
What was Hans lippershey's use for the telescope?
Kay Hans Lipphershey invented the telescope because he was a lensmaker. at the time his kids were playing outside when they discovered it, Hans didnt really create it it was his kids but he took the credit from them. people think that Galileo also created it but he did not. he took it a step further from Lipphersheys idea and just made it better. so they should both be credited. he created it also for the scientists and mathematicians in that time could study the planets and solar system. by Liam
Why are telescopes in deserts?
Telescopes are often located in deserts because deserts offer very dry and clear atmospheric conditions, which are ideal for observing celestial objects. The dry air minimizes atmospheric distortion, providing astronomers with clearer and more detailed images of the night sky. Additionally, deserts have fewer artificial lights, reducing light pollution that can interfere with astronomical observations.
The location of the original ' Hand with reflecting sphere'?
The original "Hand with reflecting sphere" sculpture by M.C. Escher is located in the Escher Museum in The Hague, Netherlands. The museum is housed in a former royal palace, known as the Lange Voorhout Palace.
Astronomers discovered a large dark storm on Neptune, which they named the Great Dark Spot. This storm was similar in size to Earth and displayed winds up to 1,500 mph. Its presence surprised astronomers because it had not been observed during the Voyager flyby missions in the 1980s.
What is Edwin hubble father name?
Edwin Powell Hubble was the third of seven children of John P. Hubble, an
insurance executive in Marshfield, Missouri, and Virginia Lee James Hubble,
a descendant of American colonist Miles Standish.
What is the distance from the sun and the Hubble telescope?
The Hubble Space Telescope orbits Earth at an altitude of about 547 kilometers (340 miles). The distance from the Sun to Earth varies due to Earth's elliptical orbit, but on average it is about 149.6 million kilometers (93 million miles).
How does a telescope lens make things appear closer?
A telescope lens gathers and focuses light from distant objects, producing an image that appears magnified. By bending and converging the light rays, the lens creates a larger image on the retina of the eye, making objects appear closer and more detailed than they actually are.
Why do reflecting telescopes use concave mirrors?
In space there is no interference by Earth's atmosphere.
In space there is no interference by Earth's atmosphere.
In space there is no interference by Earth's atmosphere.
In space there is no interference by Earth's atmosphere.
In what year was the first discoveries with the newly invented telescope are made?
The earliest know working telescopes appeared in 1608 by Hans Lippershey.
What speed does the hubble telescope travel?
The Hubble Space Telescope orbits Earth at a speed of about 17,000 miles per hour (27,000 km/h). At this speed, it completes an orbit around Earth approximately every 97 minutes.
How does refraction help a microscope?
Refraction in a microscope helps to bend light rays, allowing the objective lens to focus on a specimen and magnify it. By bending light through the specimen, the microscope can produce a detailed image of small structures that would otherwise be invisible to the naked eye.
Did the invention of the telescope lead to more inventions?
Yes, the invention of the telescope led to further advancements in science and technology, including improvements in optics, astronomy, and the development of other optical instruments. It revolutionized our understanding of the universe and paved the way for discoveries such as the moons of Jupiter and the rings of Saturn.
Does the reflecting telescope deal with sound or light?
The reflecting telescope deals with light. It uses mirrors to gather and focus incoming light from distant celestial objects for observation. Sound waves are not used in reflecting telescopes.
How long does it take for the Hubble telescope to orbit the moon?
Because the Space Shuttle will have to fly at a higher altitude and different inclination that if it was going to the ISS (International Space Station), it will take a little under 3 days to get there. The Hubble Telescope operates past the reach of the Earths Atmosphere, at an orbit of approximately 360 miles above the Earth. Although it could techincally reach it sooner, there is a slight chance that the Space Shuttle may encounter some space junk, especially after the recent collision of two satellites orbitting the planet.
Hand lenses do not refract light themselves. They allow you to see objects more clearly by magnifying them. Refraction of light occurs when light passes through different mediums with varying densities or refractive indexes.
Did the Americans launch the Hubble telescope?
Yes, the Hubble Space Telescope was launched by the United States space agency NASA in 1990. It has provided invaluable insights into our universe and has made countless discoveries in the field of astronomy and astrophysics.
Explain the process of refraction and an example?
Refraction is the phenomena that occurs when a ray of light changes direction when it passes through a medium with a different refractive index.
This is observable as by submerging an object half in water half out. It looks like at the surface of the water the object, lets say your arm for example, is in the water at a different angle than it is outside of the water.
What are the advantages and disadvantages of microwave telescopes?
Microwave transmission also requires line of sight in order to work properly. In order to allow two way communications two frequencies are used. However, this does not mean that there has to be two antennas because the frequencies can be dealt with by one antenna at both ends.
The distance covered by microwave signals is based upon the height of the antenna. In order to increase this coverage each antenna has a built-in repeater that regenerates the signal before passing it on to the next antenna in line. The placement of the antenna to do this is approximately 25 miles.
The main drawback of microwave signals is that they can be affected by weather, especially rain.

How much does it cost to make an observatory?
The cost of building an observatory can vary widely depending on factors such as size, location, design, equipment, and technology. Small private observatories can cost tens of thousands of dollars, while larger professional observatories can cost tens of millions of dollars. Maintenance, staff salaries, and ongoing operations also contribute to the overall cost.
What effect might a hole in the ozone layer have on the receptivity of a UV telescope?
A hole in the ozone layer would increase the amount of harmful UV radiation reaching the Earth's surface, potentially affecting the sensitive components of a UV telescope. This increased exposure to UV radiation could degrade the telescope's optics and detectors, leading to decreased performance and accuracy of observations. Regular maintenance and protection measures would be necessary to mitigate these effects.
On what does the light collecting power of a telescope depend?
The light collecting power of a telescope depends on the diameter of its objective lens or primary mirror. A larger objective lens or mirror can gather more light, allowing the telescope to produce brighter and clearer images of celestial objects.
How did Galileo support this theory after he invented the telescope?
Although Galileo's telescope was the first to be used for astronomical purposes, he didn't invent
the telescope.
A man named Hans Lipperhey invented the telescope. Many people claimed to have invented the telescope however Hans Lipperhey was the only one to apply for a patent.
How have the chandra and hubble telescopes helped scientists?
The Hubble space telescope uses optical sensors to gather data of distant objects; as it is located outside of the Earths atmosphere it is not subject to the distortions associated with terrestrial telescopes.
The Chandra (X-ray observatory) gathers x-ray data about the universe; again, this cannot be achieved with terrestrial based observatory instruments
