Hubble Space Telescope

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.

As far as we know, the farthest that human beings have gone from the earth's surface has been in the Apollo command modules that orbited around the far side of the moon. Give them credit for maybe a quarter million miles from earth ... 250,000 miles. -- about 1 percent of the distance to Venus when it's closest to earth; -- about 1/2 percent of the distance to Mars when it's closest to earth; -- about 1/4 percent of the distance to the sun.

Mercury orbits very close to the Sun and looking near to the Sun could damage the telescope.

No. The Hubble Space Telescope was built on Earth and launched into space. It is about the size of a bus.

Otherwise it won't remain pointed at the same spot in space any longer.

Edwin Hubble started his work at the University of Chicago, but he also spent some time a Oxford in England. He also founded the Mount Wilson Observatory in California and worked at the Mount Palomar Observatories, also in California.

Impossible to answer !... The Hubble Space Telescope is not located at a fixed point (geo-stationary orbit). It orbits the earth once every 95 minutes (approx) - at an inclination of 28.5 degrees. Therefore - although its position relative to the equator is fixed - it travels across the visible sky.

The Hubble Space Telescope was launched in the cargo bay of a Space Shuttle that took off from the Kennedy Space Center in Florida, US.

There are a few reasons. When you watch the stars at night, you’ve seen how they twinkle. This is because of atmospheric distortion, and that really hampers the ability of telescopes on Earth to get clear images. Since the Hubble is above the atmosphere, it isn’t affected by atmospheric distortion - for Hubble, the stars don’t twinkle.

Another reason is that Hubble doesn’t have to contend with light pollution. Telescopes are places in areas where they sky is affected as little as possible by light, but there’s always some light.

Another is that Hubble can take very long exposures. Telescopes on Earth are limited to observations at night, but Hubble can take very long exposures, and can observe an object indefinitely.

The Hubble telescope traveled to space aboard the Space Shuttle Discovery on April 24, 1990, on mission STS-31. There were four subsequent shuttle servicing missions, the last by STS-125 on May 13-19, 2009.

The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. Although it has taken photos from other galaxies, it does not have the capability of capturing a single image of 100 billion galaxies on one photo.

Hubble Deep Field was created in 1995.

Hubble Deep Field South was created in 1998.

The characteristics of the space hubble is that it makes use of the telescope.
