The telescope

Galileo suggested that this was due to their immense distance from Earth.

Why did hans lippershey invent the telescope

Apart from his significant contributions to astronomy , he was instrumental in the field of optics in general. He managed to do that not on his own, but using almost 2 thousand years of slowly growing experience that was gathered by Indian, Egyptian, Chinese, Greece, Roman and Arab scientists. Gamma-ray telescopes less than 0. In it he reported on his observations of the Moon, Jupiter and the Milky Way. These were consequently termed aerial telescopes. The next discovery, that of sunspots, was made by several observers, including Galileo, independently. It surveyed the entire sky detecting , infrared sources—more than times the number previously known. He also made all the tube, mount , and fittings. He showed the latter device to the Venetian senate, hoping to impress them with its commercial and military potential. Magnifying glasses became common in the thirteenth century, but these are cumbersome, especially when one is writing. Over the next several decades, lens-grinding and polishing techniques improved gradually, as a specialized craft of telescope makers slowly developed.

The government of the Netherlands eventually turned down both applications because of the counterclaims. In short, it was the prototype of modern scientific instruments.

history of the telescope

The Compton Gamma Ray Observatory was a big improvement on previous surveys. Although the magnifying and diminishing properties of convex and concave transparent objects was known in Antiquity, lenses as we know them were introduced in the West [1] at the end of the thirteenth century.

Types of telescope

Using his telescopes, Herschel was able to discover some moons around the gas giants, notably Titania and Oberon of Uranus and Uranus itself. His first telescope had a 3x magnification, but he soon made instruments which magnified 8x and finally, one nearly a meter long with a 37mm objective which he would stop down to 16mm or 12mm and a 23x magnification. He discovered his solution by studying the human eye. A painting by H. Johannes Kepler studied the optics and designed a telescope with two convex lenses, which made the images appear upside down. Stars in the Milky Way Even through a telescope the stars still appeared as points of light. And it is like the face of the earth itself, which is marked here and there with chains of mountains and depths of valleys. He also discovered the rings of Saturn, sunspots and four of Jupiter's moons. Many ground-based radio telescopes can study microwaves. From the time of the invention of the first refracting telescopes it was generally supposed that chromatic errors seen in lenses simply arose from errors in the spherical figure of their surfaces.

It remains in good health to this day and is expected to overlap some observations with the James Webb Space Telescope Hubble is part of a set of four "great observatories" launched by NASA in the s and s. Deployment is now scheduled for launch in May from French Guiana. William Herschel oversaw the construction of a meter long Newtonian based reflector telescope.

An Englishman, Chester Moore Hallgreatly reduced the chromatic aberration of refracting telescopes when he introduced a new form of a lens.
