Hubble Space Telescope
The Hubble Space Telescope, named for noted American astronomer Edwin Hubble, was built by NASA and launched into orbit aboard Space Shuttle Discovery (STS-31) in April 1990. It can observe the visual, ultraviolet, and infrared light spectrums, and is one of four space telescopes in NASA's "Great Observatories" Program.

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 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.
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.
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
It only has to remain stable around the 3 axes through its center of mass. That's 'relatively'
easy to accomplish with gyros and heavy flywheels. Once 3-axis stability is achieved, it doesn't
matter where the whole thing goes ... it still stays pointed toward the same field of view for
long exposures. (Just remember to rig a timer to close the shutter when the earth is in that
direction from it, to avoid sunlight or artificial light from the surface being added to the exposure.)
Actually ... you know what ? That may actually be easier in space than it is on the surface
of the revolving earth. Never thought about that before!
Does the Hubble telescope show living stars of just the light from the star?
Any time you see something, with your eyes or with an instrument, it is because light from the object reaches you. This light takes a while to reach you; if the object is at a distance of 30 centimeters, it will take a nanosecond; if it comes from the star Rigil Kentaurus, it will take over 4 years, and if it comes from the galaxy M31, it will take 2-3 million years. That means that if we see the light from a distant star, it may already be dead (from a certain point of view - see the definition of simultaneity in the Theory of Relativity).
For what purpose are most telescope designed?
Most telescopes are designed for observing distant celestial objects such as stars, planets, galaxies, and nebulae. They are used for tasks like astronomical research, astrophotography, and amateur stargazing.
What is the magnitude of the hubble telescope?
"Magnitude" is not a term that's usually used to describe a telescope, although
it's commonly used to describe the objects the telescope observes.
Down below this answer, we've added three links that will take you to sites that are
packed full of information on the Hubble Space Telescope. If the test is tomorrow,
then you probably ought to get cracking.
How might the Hubble Space Telescope change today's model of the solar system?
The Hubble Space Telescope has provided invaluable data on various bodies in our solar system, leading to a deeper understanding of their composition, behavior, and interactions. By capturing high-resolution images and studying the dynamics of celestial bodies, the Hubble telescope continues to refine and enhance our current model of the solar system.
Can the Hubble Space Telescope detect infra-red light?
HST's Near-Infrared Camera/Multi-Object Spectrometer(NICMOS), installed on Servicing Mission 2 in 1997, and repaired during Servicing Mission 3A, was installed specifically to observe the infrared spectrum.
The James Webb Space Telescope (formerly the Next Generation Space Telescope), currently in final design reviews (the final step prior to manufacturing and testing) is designed as an outer orbit (past the Moon) infrared space telescope. The technology involved in such a device has caused a few delays, as the temperatures at that distance are much colder than in Earth orbit, and present different challenges for a device that must respond to precise commands, as well as one that can't be repaired.
What does the hubble space telescope look at?
The main purpose was to collect pictures, as it was, and is, a very high-tech and high-quality telescope. It was constantly take billions of pictures throughout each day, and send them back to NASA.
What is the job the hubble space Telescope?
to take photographs of very distant galaxies, and show data of them to NASA. It is used, because there is too much light pollution in a lot of places on Earth, making it hard to use a telescope, but in space there is no light pollution (therefore, it can see the galaxies that we can't see on Earth).
Money, it all comes down to money. The Hubble telescope is a multimillion dollar thing, i think its total cost is in the billions. So imagine what a better one would cost! Plus, the Hubble telescope has been able to do everything we needed it to. So until it can't keep up, i think we will keep good old Mr Hubble.
Who was named after the hubble space telescope?
The asteroid 107P was named "Hubble" after the Hubble Space Telescope. This was done to honor the contributions of the telescope to astronomy and space exploration.
What is the James Webb space telescope going to study?
It is going to replace the Hubble Space Telescope in the year 2018. It will study the edges of the universe, where the light from the creation of the Universe is still in transit to the Earth. So what JWST will do is to look at the past, billions of years ago, when the Universe was only a few hundred million years old. This would help us understand more about the evolution of the Universe.
What is a disadvantage of having a telescope in space?
There are also disadvantages of having telescopes in space 1 is that they are expensive to run and maintain each launch can cost millions of dollars and building the telescope can cost many million as well. Transmitting the information to earth can take longer then telescopes on the ground and can require more power.
What is the Difference between hubble space telescope and iternational space station?
There are a number of differences. First, they are in different orbits; the Hubble is higher than the ISS. The ISS is a lot bigger. Probably the most important difference is that the Hubble has a big telescope but no people, while the ISS has people but no big telescope.
What fuel does the Hubble Space Telescope run on?
HST uses no fuel at all - it was designed to be an orbital repair satellite from the beginning, and the Shuttle that performs each Servicing Mission boosts it back into a higher orbit after they're done working on it. All power comes from the huge twin solar panels on each side. Since no more missions are planned (don't hold your breath - HST is NASA's largest PR cash cow), HST will eventually decay until it burns up in the atmosphere.
Why do you need space boots in space?
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.
What shuttle was used to repair the Hubble Space Telescope in 1993?
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.
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".
Only because it gets no atmospheric interference, which most of the ground based telescopes do.
Space Shuttle Discovery, mission STS-31.
Yes, the Hubble Space Telescope was built to observe objects in space without the distortion caused by Earth's atmosphere. By being located above Earth's atmosphere, the Hubble Telescope can capture clearer and more detailed images of celestial objects.
What is the hubble telescope made out of?
How is a telescope made?
A telescope is a device used to form images of distant objects. The most familiar kind of telescope is an optical telescope, which uses a series of lens-1 or a curved mirror to focus visible light. An optical telescope which uses lenses is known as a refracting-telescope or a refractor; one which uses a mirror is known as a reflecting telescope or a reflector. Besides optical telescopes, astronomers also use telescopes that focus radio waves, X-rays, and other forms of electromagnetic radiation. Telescopes vary in size and sophistication from homemade spyglasses built from cardboard tubes to arrays of house-sized radio telescopes stretching over many miles.
The earliest known telescope was a refractor built by the Dutch eyeglass maker Hans Lippershey in 1608 after he accidentally viewed objects through two different eyeglass lenses held a distance apart. He called his invention a kijker, "looker" in Dutch, and intended it for military use. In 1609, the Italian scientist Galilei built his own telescopes and was the first person to make astronomical observations using them. These early telescopes consisted of two glass lenses set within a hollow tube and were rather small; Galileo's largest instrument was about 47 inches (120 cm) long and 2 inches (5 cm) in diameter. Astronomers such as Johannes Kepler in Germany and Christian Huygens in Holland built larger, more powerful telescopes throughout the 1600s. Soon these telescopes got too large to be easily controlled by hand and required permanent mounts. Some were more than 197 feet (60 m) long.
The ability to construct enormous telescopes outpaced the ability of glassmakers to manufacture appropriate lenses for them. In particular, the problems caused by chromatic-aberration (the tendency for a lens to focus each color of light at a different point, leading to a blurred-2 image) became acute for very large telescopes. Scientists of the time knew of no way to avoid this problem with lenses, so they designed telescopes using curved mirrors instead.
In 1663, the Scottish mathematician James Gregory designed the first reflecting telescope. Alternate designs for reflectors were invented by the English scientist Isaac Newton in 1668 and the French scientist N. Cassegrain in 1672. All three designs are still in use today. In the 1600s, there was no good way to coat glass with a thin reflective film, as is done today to make mirrors, so these early reflectors used mirrors made out of polished metal. Newton used a mixture of copper, tin, and arsenic to produce a mirror which could only reflect 16% of the light it received; today's mirrors reflect nearly 100% of the light that hits them.
It had been known as early as 1730 that chromatic aberration could be minimized by replacing the main lens of the telescope with two properly shaped lenses made from two different kinds of glass, but it was not until the early 1800s that the science of glassmaking was advanced enough to make this technique practical. By the end of the 19th century, refract telescopes with lenses up to a meter in diameter were constructed, and these are still the largest refracting telescopes in operation.
Reflectors once again dominated refractors in the 20th century, when techniques for constructing very large, very accurate mirrors were developed. The world's largest optical telescopes are all reflectors, with mirrors up to 19 feet (6 m) in diameter
