"Could have used a pretty ordinary telescope," Maddson's assistant suggested.

NASA has an ordinary telescope in space but no big radio telescope.

Those sensors used heat emissions to locate and identify objects, just as an ordinary telescope uses light.

About 40 spectroscopic binaries-that is, stars seen single in ordinary telescopes, but proven to be double by means of the spectroscope-were discovered in 1898-1902.

Despite the distance involved, you will be able to see the flash of the explosion with an ordinary telescope when the antimatter explodes on the Red Star.

In fact all ordinary telescopes would do so but for the addition of an extra lens-system to turn the image the right way up again.

It is actually a binary, but the two components are so close together that they cannot be separated with ordinary telescopes.

An ordinary telescope allows people to see light from distant objects.

Scientists are also trying to do this with ordinary telescopes.

In an ordinary telescope of 3 feet one can distinguish the stars.
