Telescopes And Observatories Quiz

The Hubble Space Telescope, launched in 1990, revolutionized astronomy by providing high-resolution images of distant galaxies, nebulae, and planets. It operates above Earth’s atmosphere, avoiding distortion from air turbulence.

The Very Large Telescope, located in Chile’s Atacama Desert, is operated by the European Southern Observatory. It consists of four main telescopes, each with an 8.2-meter mirror, enabling deep-sky observations.

Reflecting telescopes use curved mirrors instead of lenses to collect light. This design, pioneered by Isaac Newton, avoids chromatic aberration and allows larger apertures than refractors.

The James Webb Space Telescope focuses on infrared wavelengths, allowing it to study the early universe, peer through dust clouds, and detect heat from distant planets and galaxies.

Refracting telescopes, also known as refractors, use a system of lenses to bend light and converge it at a focal point to create a magnified image. This is a fundamental type of optical telescope.

Isaac Newton built the first functional reflecting telescope in 1668, using a curved mirror to focus light and reduce chromatic aberration seen in refractors.

The Spitzer Space Telescope operated from 2003 to 2020, observing the cosmos in infrared and revealing details of distant galaxies, stars, and exoplanets.

The Hubble Space Telescope orbits in low Earth orbit, about 547 km above the surface, enabling direct servicing by space shuttle missions in the past.

The Event Horizon Telescope is a network of radio telescopes worldwide that captured the first image of a black hole’s event horizon in 2019.

The Chandra X-ray Observatory, launched in 1999, studies X-ray emissions from supernova remnants, black holes, and hot gas in galaxy clusters.
