Hubble Space Telescope

The Hubble Space Telescope is the most famous and the best working EVER MADE!

Solar energy, all space equipment uses solar panels

no

The HST is located in space. It flies round the Earth once in 97 minutes; so the actual position is changing constantly.

The Hubble space telescope is in near Earth orbit at a orbital height of 559 km (347 miles)

The Hubble telescope was the first telescope built by NASA and placed into orbit. The original launch for the telescope was delayed because of the disaster seen by the Challenger.

The HST is a collaboration between NASA and the European Space Agency. The Space Telescope Science Institute (STScI) is responsible for the scientific operation of the telescope and delivery of data products to astronomers.

In space, there is no interference by Earth's atmosphere.

The Hubble Space Telescope never carried any living being. It has been maintained and updated

by astronauts who navigated to it aboard the Space Shuttle, but never served as a vehicle for

anybody's transportation.

The Hubble Space Telescope uses mirrors to gather and focus incoming light. The primary mirror is 2.4 meters in diameter and collects light from celestial objects to produce high-resolution images. Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.

Galaxies are moving away from each other in a constantly expanding universe.

Hubble being in space does not have a problem of seeing which is caused by atmospheric blurring and thus can observe light at more wavelengths. Its only limitation is by diffraction in its optics

The Hubble telescope is in space so it doesn't have a problem with atmospheric distortion. Therefore The Hubble telescope get's a much clearer picture than any normal land telescope which gets a less clear a picture because of water vapour and diffraction of light.

The telescope in orbit around the earth as of 2010 is the Hubble Telescope.

Of course. Every human, and every scientist, makes some errors. Nobody gets things right ALL the time.

Even Albert Einstein has been proven wrong about some things. Einstein distrusted quantum mechanics, referring to quantum mechanics' somewhat random elements saying "God does not throw dice with the universe".

But Einstein was wrong about that. Every scientist makes mistakes; the point is to acknowledge them when you discover your errors, and correct them.

I'm not convinced that your proposition is correct. I realize that cosmologists use a lot of simplification in their descriptions, for friendly reasons, but I always prefer to keep things fairly straight. It is my reading of Hubble that he postulated that remote galaxies were receding -- at the time they emitted the light which we are now receiving -- from us at a speed which was proportional to the distance from where they were then to where we are now. How one interprets the concept of distance, in view of the separately postulated "expansion of space" and time-dependence of the "scaling factor" is obviously now a compounding, related issue, which lay outside Hubble's purview. Hubble's law does not specify, based upon the observed redshift (whether non-Doppler or not) what is (i.e. is now) the distance between us and the galaxy. It is considered simplest to assume that the velocity of separation is and continues radially uniform, and therefore has increased during the time it took the light to reach us. If you need to know the current (our observing time) location of the remote galaxy and the velocity of its separation from us now, you will need to apply further calculations to the Hubble data.

a major difference the huble space telescope is in orbit while the regular is in use only on the ground

No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.

Hubble has never "explored" Neptune. It is a telescope in orbit round Earth and from Earth it has "imaged" Neptune. It has done this several times eg 1996 and 1998 (there may be more times!).

I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.

The Hubble Space Telescope was named after American astronomer Edwin Hubble, who made significant contributions to the field of observational cosmology. Hubble is best known for demonstrating the expansion of the universe through his observations of galaxies moving away from Earth.

The problem with Hubble Space Telescope (the HST, or just the "Hubble") was that the primary reflector, that is, the mirror which redirects the incoming light to focus it, was ground using an incorrectly calibrated reference as a guide. This left it "out of focus" in areas farther from the center. There were a couple of checks for accuracy made with secondary references, and they were off, but the "warning" was ignored and the opinion was offered that the two secondary references were not as accurate as the primary reference was. More information can be had by reading the Wikipedia post on the Hubble. A link to that post can be found below.
