Includes bibliographical references (p. 91-92) and index. Discusses early astronomical studies and the primitive tools used, the development of telescope technology, and the role telescopes have played in expanding our knowledge of the universe.

This was a discovery made possible by an invention; the telescope. Galileo saw his first telescope in late 1608 and instantly recognized that a more powerful telescope could be the answer to the prayers of every astronomer. By late 1609 Galileo had produced a 40-power, two-lens telescope. That 1609 telescope was the first practical telescope for scientific use. A paper by Johannes Kepler describing the orbits of the planets convinced Galileo to believe the theory of Polish astronomer Nicholaus Copernicus, who first claimed that the sun was the centre of the universe, not the earth

The telescope is one of humankind's most important inventions. The simple device that made far away things look near gave observers a new perspective.

The telescope is one of humankind's most important inventions. When curious men pointed the spyglass toward the sky, our view of Earth and our place in the universe changed forever. But who invented the telescope? The answer remains a mystery today. The first person to apply for a patent for a telescope was a Dutch eyeglass maker named Hans Lippershey (or Lipperhey).

History of the telescope. Early depiction of a "Dutch telescope" from 1624. Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece. Galileo improved on this design the following year and applied it to astronomy.

The era of radio telescopes (along with radio astronomy) was born with Karl Guthe Jansky's serendipitous discovery of an astronomical radio source in 1931

The era of radio telescopes (along with radio astronomy) was born with Karl Guthe Jansky's serendipitous discovery of an astronomical radio source in 1931. Many types of telescopes were developed in the 20th century for a wide range of wavelengths from radio to gamma-rays.

The Discovery of Heaven. The Discovery of Heaven. The divine being, however, cannot himself travel to Earth, and on several occasions in the book resorts to influencing events, being in effect a deliberate personification of deus ex machina.

The history of the telescope dates back to the early 1600s. Galileo was the first to use a telescope for the purpose of astronomy in 1609 (400 years ago in 2009, which is currently being celebrated as the International Year of Astronomy). Regardless of the inventor, most of the earliest versions of the telescope used a curved lens made of polished glass at the end of a tube to magnify objects to a factor of 3x. To learn more about how a telescope lens works, read our article on the telescope lens in the Guide to Space.
