The Hubble Space Telescope orbits Earth and sends images of distant objects. Why does Hubble form better images than the optical telescopes used on land?

Because it works with pure, fresh, clean light, and not the stuff
that has been dragged through several miles of air first.
By the way ... there's only one single Hubble Space Telescope. On
April 24, 2014, it'll polish off a cool 24 years operating in Earth orbit !

The air is much clearer in such places due to the atmosphere being thinner. Where the Hubble is, there is virtually no atmosphere so they get a much clearer and less distorted view.

For one thing, being above most of the atmosphere means that there is very little atmospheric distortion; also, since the atmosphere is less transparent to certain wavelengths, spectra measured at the Hubble are better able to determine some types of information than those obtained at ground-based instruments.

slosh through air before it enters the telescope.

Which type of telescope is most similar to an optical telescope?
No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.
What is Optical instrument and give the example?
glasses binoculars telescopes dats all i got soz =)
Uses lenses or mirrors to gather and focus starlight?
optical telescope
What did Janssen discover?
Zacharias Janssen was the first person to invent the optical telescope. He is also known as the inventor of the compound microscope.
What instruments scientists use to study the universe?
anything likeSeismometers- Are used by seismologyto measure and record the size and force of seismic-wave.Tilt meter- is an instrument designed to measure very small changes from the horizontal level, either on the ground or in structures.Richter scale- Measure of the magnitude of seismic waves from an earthquake.Magnetometers- An instrument for measuring the magnitude and direction of a magnetic fieldAnemometer- Is an instrument use to determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
What discovery did the optical telescopes make?
the optical telescope has discovered objects on earth and in space
What instruments use lenses or mirrors to collect and focus light from distant objects?
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
An optical instrument that forms enlarged images of distant objects is called a?
a telescope
What is a definition of telescope?
A telescope is an optical system used to make objects, especially distant objects, appear larger/closer.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What is catadioptric telescope?
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Which optical device device uses mirrors and lenses to magnify images of distant objects?
A telescope can do that, but magnification is not its purpose.
How do radio telescope operate?
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
What type of telescope is most often used to view distant objects?
Reflecting telescopes are far-and-away the most common. This is because the telescope can be smaller and lighter, and because lenses always absorb a little light while mirrors can be almost perfect reflectors.
The light from distant stars and other objects can be distorted in many ways which type of optical telescope best avoids the problem caused by distortion?
Space Telescope such as the Hubble Space Telescope
What design variants might one see in an optical telescope?
Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
