It's the gravitational effect of the Sun combined with the inertia of the planets.
Their inertia (Newton's first law of motion) would make the planets move in straight lines, but the gravitational force makes them follow elliptical paths and they orbit the Sun.
The object is moving forward at high speed and tends to travel in a straight line. But the gravitational pull of the Sun causes it to accelerate towards the Sun. The combined effect is that the object's path bends sideways, continuously.
The centripetal force exerted on the telescope by gravity is balanced with the centrifugal force of the object exerted on e.g. earth.
gravity is the answer
well i think its uptrust
air resistance
The sun's gravitational pull keeps the earth in orbit around it.
satellites that spy typically in a low earth orbit with a big telescope looking down at the ground, like google satellite on steroids
Because the moon moves with a certain speed in its orbit, that orbital motion produces a centrifugal force which opposes the attraction of gravity. The balance between gravity and centrifugal force keeps the moon in orbit. The moon continues to orbit at the speed it does, because of its inertia. Moving in the vacuum of space, the moon does not encounter resistance to its motion. There is, however, some energy lost as a result of tidal forces, and that will, over a very long period of time, eventually alter the moon's orbit.
There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
telescope or maybe binoculars
The telescope in orbit around the earth as of 2010 is the Hubble Telescope.
the first telescope built by NASA placed into orbit was the hubble space telescope.

The Hubble Space Telescope (HST) is a space telescope that was carried into orbit in April 1990.
Gravity and Inertia keeps the earth in orbit
The use of a telescope from orbit is going to be more clear. It is not very easy to do so, though. The orbit eliminates atmospheric interference. However, you have to get the telescope into orbit in order to use it. And connect to it from your remote location.

No.
The Hubble Telescope was launched into orbit on April 24, 1990.
