Teleskobu

Teleskobu is an optical instrument designed to observe distant objects by collecting and focusing light or other electromagnetic radiation. By increasing angular resolution and light-gathering power, a teleskobu reveals details invisible to the naked eye. Telescopes vary in size, wavelength range, and mounting, and can be operated from the ground or in space. They are used primarily for scientific research, education, and public outreach.

Types include refracting telescopes, which use lenses; reflecting telescopes, which use mirrors; and catadioptric designs that combine both. There are also radio telescopes that detect radio waves with large dishes, and space telescopes that operate above Earth’s atmosphere. A typical optical telescope comprises a light-gathering objective (lens or mirror), a tube or enclosure, and a mounting system for aiming and tracking. Detectors may be eyepieces, photographic plates, CCDs, or spectrographs, depending on the intended observations.

History shows that the first practical telescopes appeared in the early 17th century in the Low Countries, with inventors such as Hans Lippershey contributing to their development. Galileo Galilei popularized telescopic astronomy in the following years by observing the Moon, the four Galilean moons of Jupiter, and other celestial objects. Isaac Newton introduced the reflecting telescope in 1668 to minimize chromatic aberration. In the modern era, space-based telescopes like the Hubble Space Telescope and the James Webb Space Telescope, along with large ground-based arrays, have expanded observational capabilities across multiple wavelengths and disciplines.

Teleskobu continue to drive advances in astronomy, planetary science, cosmology, and related fields, while also supporting education and citizen science.
