"A leader in Rochester's world-class optics and photonics industry, Harris employees are making history by manufacturing the world's largest terrestrial telescope
active secondary mirror system in Rochester, N.Y.
Summary: BEIRUT: Those born in the late 20th century are familiar with the way the lunar landscape looks when photographed through a high-power terrestrial telescope
. It requires more imagination to place such images alongside those of ruined human bones.
One might now ask--if Digges had had access to optics similar in size and focal length to those that I used, would he have produced a viable terrestrial telescope
? I am sure that the answer is a definite YES!
On Earth, some infrared wavelengths can't penetrate the atmosphere, and others are overwhelmed by the glare of a terrestrial telescope
's own heat.
Many astronomers are demanding a space telescope because terrestrial telescopes
are unable to detect objects on the other side of the Sun.
Using sensors that analyse the shape of light waves from either natural or artificial guide stars--the latter produced by focusing a set of lasers into the earth's atmosphere--and sophisticated deformable computer-controlled mirrors, terrestrial telescopes
can correct for the distortion caused by the turbulence of the Earth's atmosphere in real time, enabling significantly sharper images.
The first pulsar readings proved the efficiency of HESS for inter-stellar observations from terrestrial telescopes
The comet was not visible to any terrestrial telescopes
due to its proximity to the sun but several spacecraft routinely observe the solar atmosphere and the comet was to be visible to them.
