Hubble space telescope orbits earth at about 600 kilometers above Earth's surface.It have a main mirror of 2.4 meters.It works in Visible light, infra red and UV wave lengths..It studies Planets, stars, Galaxies and universe.
Kepler space telescope looks for transit of planets.When a planet crosses infront of a star it gets dimmer by a small amount..By studying the period and reduction of light it detects EXo planets.It looks in a particular area of Cygnus, Lyra and Draco constellations for main sequence stars numbering about 145000 in number.
Its main mirror is 0.95 meters.It is orbiting sun in earth trailing orbit.

What is Hubble's Law and how does it relate to Hubble's constant?

Hubble's law has to do with the . Space is expanding, every portion of it receding from every other, and the more distant two objects are, the faster they recede...

If the Hubble Space Telescope proved that Hubble's constant is actually half as large as it is currently believed to be, what would the implied age of the universe be in comparison to the current accepted value?

The dimension of Hubble constant, $[H_o]-LL^(-1)T^(-1)=T^(-1)$. The dimension of thr reciprocal $[1/H_o]=T$ As of now, different estimates of $H_o$ have a range around 70 km/s/mega parsec. The reciprocal, after unit...

Are there any Hubble Telescope pictures of quasars or have they only been detected by radio telescopes?

See the Hubble site - not all of the photographs are quasars, but their are a few. Remember that Hubble takes greyscale images at a number of wavelengths. Not all...

The Hubble telescope captured galaxies in the eastern direction of the universe. Images came back proving that galaxies are made up of different colors. What would explain the reason for the make of colors in galaxies?

Galaxies early on in their lives are actively forming hot, new stars and appear more bluish. Older galaxies are forming fewer new stars and their constituent stars are older on...

How are pictures of the sun taken? For example, how do devices such as the Hubble Telescope take pictures of solar flares?

While the Hubble never takes pictures of the sun, , and all do, as well as a number of ground based telescopes. Usually they use a variety of...

How does the Hubble Space Telescope work?

To observe astronomical objects trouble free from cloud and other problems in Earth's atmosphere it is placed i n ,.low Earth orbit. The focused light from objects go to charge...

How does the Hubble Telescope see back in time?

It has to do with how fast the light travels from those stars and other things. Since those things are extremely far away from the telescope the light that’s being...

Considering the Hubble Space telescope was launched in 1990, how many megapixel does hubble telescope have? How is it able to keep up with modern technology?

The Hubble telescope collects data in analog form. That is because it is a concave mirror which collects light wave and sends them in a focused form to its receivers....

What is the resolution of the Hubble space telescope? What would the resolution of the Hubble Space Telescope be if it were a digital camera? Gigapixels? Terapixels?

Hubble is not like a regular digital camera in that it doesn't take a single image in one shot. The Hubble's CCD cameras can take monochrome images at a resolution...

What are some advantages and disadvantages for using an ultraviolet telescope? Why is at better/easier or harder to use a UV telescope than another telescope like a radio telescope or an infrared telescope?

So we have to send them to earth orbit above our atmosphere which filters radiations.Certain objects emit only radiation in UV range.So to study them we have to use UV...
