Hubble Space Telescope

The James Webb Space Telescope was developed after the Hubble Space Telescope. It is designed to be the successor to Hubble and will study the universe in infrared wavelengths to help answer fundamental questions about the origins of the cosmos.

Yes, the Hubble Space Telescope is expected to be retired in the mid-2020s. It has been in operation since 1990, and the James Webb Space Telescope will be its successor.

the initial problem was=== the reflecting (lens/mirror) was improperly ground due to the thickness of a 25 cent washer used in the grinding machine that made the lens. the problem was solved by insalling corrective (lenses/mirrors) shaped like pringles potato chips. sounds crazy but its true. bob winters hannacroix n y. there is a particular name for this shape but i cant remember it except that its l o n g.

The Hubble Space Telescope was named after the American astronomer Edwin Hubble, who played a crucial role in changing our understanding of the universe by demonstrating that galaxies are moving away from each other.

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.

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.

The trouble experienced with the Hubble Space Telescope included a flaw in its primary mirror, which caused blurry images. This issue was corrected during a servicing mission in 1993. Additionally, the telescope has faced challenges with a few component failures, which have been addressed through subsequent servicing missions.

Ada was the programming language initially used to program the computer on the Hubble Space Telescope. It was chosen for its reliability and high-level capabilities, specifically for real-time systems and safety-critical applications.

The Hubble Space Telescope, or HST, or just the "Hubble" for most folks, is a Ritchey-Chrétien reflector telescope. It has a primary mirror to reflect and focus the incident light. A link is provided below.

The Hubble Space Telescope orbits approximately 547 kilometers (340 miles) above the surface of the Earth. It travels at a speed of about 27,000 kilometers per hour (17,000 miles per hour), completing a full orbit around the Earth roughly every 97 minutes.

Astronomers used to make photographic plates of stars on glass, and compare the images in a device known as a "blinker." If a star moved between two separate exposures, it was clearly NOT a star but an asteroid or comet.

Today we gather light on digital plates and stack images. Computers do much of the analysis in searching for interplanetary bodies. In addition, computer technology is used to measure variations in starlight on board the Kepler spacecraft. These variations reveal the presence of new worlds. Five new worlds (exoplanets) were announced earlier this year, and Kepler astronomers are expected to announce the discover of 700 more within the next few months--more than doubling the currently known number.

Construction began in 1977 and it was ready for launch in 1985, around eight years later. It was not launched until April 24, 1990 though, due to delays from the Challenger disaster in 1986.

Once the Space Telescope project had been given the go-ahead, work on the program was divided among many institutions.

Marshall Space Flight Center (MSFC) was given responsibility for the design, development, and construction of the telescope, while theGoddard Space Flight Center was given overall control of the scientific instruments and ground-control center for the mission. MSFC commissioned the optics company Perkin-Elmer to design and build the Optical Telescope Assembly (OTA) and Fine Guidance Sensors for the space telescope. Lockheed was commissioned to construct the spacecraft in which the telescope would be housed.

Perkin-Elmer was commissioned to build the optical components of the Hubble Space Telescope. The construction of the main mirror was begun in 1979 and polishing completed in 1981 in Danbury Connecticut.

The Hubble Telescope was carried into orbit in April 1990. It is still in orbiting in space. In 2009 it had its final servicing and will probably last until sometime in 2014. Its successor, the James Webb Space Telescope (JWST), will take its' place.

The Hubble Space Telescope operates in the ultraviolet, visible, and near-infrared wavelengths, ranging from about 0.1 to 2.5 micrometers. This range allows it to capture high-resolution images and study a wide variety of astronomical phenomena in space.

The concept of getting dizzy is based on liquid that is somewhere inside your head near both of you ears. When you spin around and around, that liquid keeps swiahing around too. When you stop, the liquid is still spinning, so you still feel like your spinning. That's how you get dizzy. So yes obviously now you can get dizzy in space.

The Cassini-Huygens mission to Saturn also used gyroscopes to stabilize and control the spacecraft during its mission. Gyroscopes are commonly used in spacecraft to help maintain orientation and stability in the absence of gravity.

No, only specially designed rockets can go up into space. As soon as a helicopter reaches our atmosphere boundaries, it would burn up. Rockets on the other hand, have been specially made to hold such extreme temperatures. :)

How the telescope works In orbit about 380 miles (610 kilometers) above the earth, the Hubble Space Telescope views the heavens without looking through the earth's atmosphere. The atmosphere bends light due to a phenomenon known as diffraction, and the atmosphere is constantly moving. This combination of diffraction and movement causes starlight to jiggle about as it passes through the air, and so stars appear to twinkle. Twinkling blurs images seen through ground-based telescopes. Because an orbiting telescope is above the atmosphere, it can produce pictures in much finer detail than a ground-based telescope can. This false-color image taken by the Hubble Space Telescope using infrared light shows Uranus's rings and clouds. The different colors in the image represent different atmospheric conditions.

These forms of light, like visible light, are electromagnetic radiation. The wavelength (distance between successive wave crests) of ultraviolet light is shorter than that of visible light. Infrared light has longer wavelengths than visible light. Ultraviolet light comes from highly energetic processes, such as the formation of disks around black holes and exploding stars. Infrared light provides information about cooler, calmer events, such as the formation of dust clouds around new stars. The United States space agency, the National Aeronautics and Space Administration (NASA), operates the Hubble Space Telescope in cooperation with the European Space Agency (ESA). The telescope is controlled by radio commands relayed from NASA's Goddard Space Flight Center in Greenbelt, Maryland. Astronomers tell the telescope where to point, and computer -- driven instruments aboard the telescope record the resulting observations. The telescope transmits the data by radio to astronomers on the ground. The Hubble Space Telescope has two kinds of instruments: (1) imagers, which take pictures; and (2) spectrographs, which analyze light. Imagers are electronic detectors called charge -- coupled devices (CCD's). The CCD's convert light into electronic signals, which an on -- board computer records and sends to the ground. A spectrograph, like a prism, spreads light into its component colors, much as water droplets spread sunlight into a rainbow. The resulting band of light is called a spectrum (plural spectra). Using spectrographic data from the Hubble Space Telescope, astronomers can determine the composition of stars and galaxies--measuring, for example, the amounts of hydrogen, carbon, and other chemical elements in them How the telescope works In orbit about 380 miles (610 kilometers) above the earth, the Hubble Space Telescope views the heavens without looking through the earth's atmosphere.

I am not a science specialist, but I do have interest in this area. Space is already curved. Space curves around gravitational fields; the bigger the field the bigger the 'bend'. For example, light from distant stars will bend as it passes by the sun, or even by super-large structures like galaxies. Einstein's theories seem to indicate that it is space itself that bends, and the light travels straight through the bent space. The space of the universe itself is bent in some ways, leaving us with a space that is, according to some, finite but unbounded. COUNTERPOINT: David Harriman in his lecture "Physicists Lost in Space" makes the point that there is no such THING as space. He is correct and Einstein, siding with Plato was wrong. The lecture can be found at the Ayn Rand bookstore. COUNTER-COUNTERPOINT: Yes, space exists and yes, it can be bent....I agree with whoever posted the top answer. As far as our understanding of the universe goes, it is bent. This is needed to explain why light bends in gravitational fields without a mass (and it cannot have a mass because it moves at the speed of light and infinite energy is required to accelerate to the speed of light) Therefore, unless we change our paradigm away from Eisnteins theories (which are still held as true) Space is curved.

The magnification of any reflector telescope is given by the focal length of the mirror divided by the focal length of the eyepiece, so if the mirror's focal length is 1000mm and the eyepiece has a focal length of 10mm, then the magnification is 1000 / 10 or 100 X magnification. So, if you wish to increase the magnification you need to either change the mirror (which is impractical) or change the eyepiece (which is easy) replacing it with an eyepiece with a shorter focal length. So, if the new eyepiece has a focal length of 5mm then the magnification is 1000/5 or 200 X magnification. If you do not wish to buy an expensive complete set of eyepieces, you can buy what is called a Barlow lens which fits between the eyepiece and the telescope. These can increase the magnification by a factor of 2 or 3, but the quality of the image is not so good (as the light has to pass through the Barlow lens as well as the eyepiece). Do not forget that you cannot keep increasing magnification hoping to get better and better images. As you double the magnification, you cut the light entering the telescope by at least a half, so the image is dimmer. Most small telescopes with mirrors between 6 and 8 inches can magnify up to around 100 X effectively but anything more than this will result in the image becoming progressively darker, more grainy and generally not so clear. To get higher magnification you need much bigger mirrors of 10 or 12 inches or more. To add further complications, you will also need a substantial mount for the 'scope as any small vibration at a high magnification will result in a great deal of image shake. Also, you will need a really good motor drive to compensate for the movement of the earth, as, without such a drive at high magnifications, the image will move out of the field of view almost as quickly as you find it due to the earth's motion.

You can insure artwork created for a public space through a fine art insurance policy that covers items on public display. This type of insurance typically includes coverage for theft, damage, vandalism, and other risks that the artwork may face in a public setting. It's important to work with an insurance provider experienced in insuring art to ensure comprehensive coverage.

The HST is a consumption tax that applies to a wide range of goods and services, and it typically imposes a uniform rate on everyone, regardless of their income level.

The social disadvantage arises because consumption taxes like the HST tend to place a proportionately higher burden on lower-income individuals and families. This is because those with lower incomes spend a larger portion of their earnings on goods and services subject to the tax, whereas higher-income individuals can save or invest more of their income, reducing the percentage of their income that goes towards taxed consumption.

As a result, the HST can contribute to income inequality by disproportionately affecting those who can least afford it. This can exacerbate social and economic disparities by reducing the purchasing power of low-income households and potentially widening the wealth gap in society. To mitigate this disadvantage, policymakers may implement measures such as exemptions, rebates, or targeted credits to lessen the impact of consumption taxes on vulnerable populations.
