The Hubble Space Telescope is located in LEO. Does the telescope move faster or slower around the Earth compared with a geostationary weather satellite?

What is resolution of a telescope and What physical process limits it?
The resolution of a telescope is the telescope's ability to determine if two points are seen as two points or one smudgy point. Resolution, or resolving power is measured as an angle below which differentiation cannot be made. The resolution of a telescope is a consequence of the wave nature of light. Because waves can add to each other, or cancel each other, in a process called diffraction, the aperature of the telescope must be as large as possible compared to the distance to the objects and the wavelength of the light to give the best performance. An equation which describes the resolution of a telescope is
Why do astronomer find it difficult to locate extrasolar planets with telescope?
extrasolar planers are not bright compared to the stars they orbit For approximately the same reason that it's difficult to spot a mosquito circling a street light that is 5 miles away, with a telescope.
What is the difference with the moon view between a telescope and binoculars?
Advantage of binoculars: A stereoscopic view - more realistic. Disadvantage of binoculars: Limited power - 10X50 is about tops for comfortable, steady viewing. Advantage of telescope: If mounted, much more steady view. Higher magnifications possible. Disadvantage of telescope: "Flat" look to image (compared to binoculars), smaller field of view.
What telescope is used to see deep sky objects?
Just about any good telescope can be used to see deep sky objects. Of course, the more power a telescope has, the better the viewing will be (compared to a smaller piece of equipment). Shallow sky objects are things like an eclipse, or something "close" to earth (within the solar system). Deep sky objects lie outside our solar system, so using a telescope with a fairly large objective is a perferred choice.
How much more light would a 2-meter-diameter telescope gather compared with one that is 50 cm in diameter?
-48
What is replacing Hubble?
The Hubble Space Telescope his becoming, if not already, obsolete. The twenty-year-old telescope requires a lot of maintenance and a replacement is overdue.The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2014. Webb will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System.Another space telescope has been envisioned and is anticipated to be placed in service between 2025 and 2065. The Advanced Technology Large Aperture Space Telescope (ATLAST) is a NASA strategic mission concept study for the next generation of UVOIR space observatory. ATLAST will have a primary mirror diameter in the 8m to 16m range that will allow scientists to perform some of the most challenging observations to answer some of man's most compelling astrophysical questions.See Sources and related links for additional information.
What are the advantages of using the naked eye compared to using a telescope?
The naked eye is more portable, can be transported easily to remote locations, can be set up and ready for operation in less time than a telescope can, and it requires much less peripheral equipment and accessories to follow the motion of objects under observation, especially when the motions are unpredictable.
What is the light microscope's magnification?
That means how much larger you see something, compared to seeing it with the naked eye. The limit for USEFUL magnification is about a thousand, in the case of hte light telescope.
Why hubble spacecraft is used to explore space?
Hubble is the name of a giant telescope that is in space. It is known as the Hubble Space Telescope and it is named after Edwin Hubble, who was a famous astronomer. It is very large and because it is outside the Earth's atmosphere it can get a clearer view of the stars, constellations, galaxies and other things it looks at, compared to a ground-based telescope. It has got some wonderful photographs and many new things have been seen with it and many new things have been learned about space by using it. That is why it is so important.
How are stars brightness compared to each other?
Astronomers use the term magnitude to compare the brightnesses of stars. Really bright stars are 1st magnitude while the faintest we can see with the naked eye are about magnitude 6. A 12 inch telescope can see down to about magnitude 14 or 15. Hubble Space Telescope can see down to about magnitude 27.
What are the advantages of using a telescope compared to making observations with unaided eye?
Telescopes can make it easy to see all the way into space, where as the human eye can not see very far at all.
What satellite whose orbit is synchronized with the rotation of the earth?
Its called a geostationary satellite. Its quite far out, meaning its 24 hour orbit is quite long when compared with satellites closer in to earth. Is appears stationary in our skies, in the same spot throughout its orbit. This makes it a lot easier to track, a fixed dish can be used.
