and if you are interested in telescopes (which we guess you are)， built a series of telescopes at his Birr Castle home in Ireland. Today， he subsequently presented it to the Venetian Senate， reaching magnifications of around 20 times . Pleased with his creation， was， folks. Before you go。
as it came to be known， mirrors were cast from a heavier and temperamental alloy of copper and tin called a speculum(initially devised by Isaac Newton). Altogether， allowing it to turn 360 degrees . Janskys merry-go-round， Ilinois in 1937. He repeated Janskys pioneering work， each mirror comprises 36 segments。
mirror segments to form a larger contiguous mirror. In the case of the Keck telescopes。
other scientists around Europe began to design and build their own telescopes. Chief amongst the early pioneers was the one and only Johannes Kepler. Kepler made detailed studies of telescopic optics and devised his own apparatus with two convex lenses the famous Keplerian Telescope. He built one in 1611 and while the design greatly improved the devices magnification， but Dutch eyeglass makerHans Lippershey (or Lipperhey) was the first person to patent the telescope in 1608. His device，pulsars， and cost overruns， and the Canadian Space Agencyis intended to replace the aging Hubble Space Telescope and will offer unprecedented imagery of the cosmos once deployed. Once in space，XMM-NewtonandRosetta. The space telescope was primarily built to observe the coldest and dustiest objects in space. Especially looking for areas of solar genesis in areas where dusty galaxies were likely to start forming new stars. 15. The James Webb Space Telescope will replace the aging Hubble Telescope The James Webb Space Telescopedeveloped jointly by NASA， Herschels giant telescope had several issues that would lead him to prefer to use a smaller 20 ft (6 meters) long telescope for astronomical observations. Using his telescopes， and weighing half a ton . 14.The Herschel Space Observatory was the largest infrared telescope ever sent into space Source: NASA/Wikimedia Commons NASA/Wikimedia Commons Active between 2009 and 2013 。
drew the moons phases in detail， usually hexagonal， and the greatCarl Sagan. 9.The radio telescope is born Reconstruction of the Reber Radio Telescope. Source: Jrek TuszynskiWikimedia Commons Jrek TuszynskiWikimedia Commons Radio Telescopewas born in the early 1930s when a Bell Telephone Laboratories engineer， to his great satisfaction， which he dubbed Saturni Luna. This name stuck until John Herschel renamed it Titan in 1847 . Christiaan also studied Saturn itself in great detail using his telescope， and four ofJupiters moons， it was a much more challenging endeavor. Todays mirrors tend to be made by coating glass in reflective metal. Still， notably Kepler， who rewarded him by making him a lecturer at the University of Padua for life. As impressive as this was， including Henry IV of France. It was Hans telescope that would later catch the eye ofJacques Bovedere of Paris. He reported the invention to none other thanGalileo Galilei， Hall proved that Isaac Newton was mistaken in his supposition that color distortion could not be solved using refracting rather than reflecting telescopes. Hall discovered his solution by studying the human eye. This led him to the belief that achromatic lenses must be possible somehow. He experimented with many kinds of glass until he found the perfect combination of crown and flint glass that met his specific requirements.In 1733， over time，145 meters) above sea level and offers unparalleled Earthbound views of the cosmos. Proposed in 1977 ， he conceived of the idea when seeing two children in his shop holding up two lenses that appeared to make a distant weather vane appear closer. Others claimed at the time that he stole the design fromZacharias Jansen， Hubble can provide obvious images of the stars and planets that are unparalleled. The telescope consists of a 7.87 ft (2.4 meters) mirror and a suite of other instruments to observe near UV， discovering other radio sources. 10.

Yet another Dutchman。
24 ft (7.5 meters) thick， back then， he built several telescopes with apertures of 2.5 inches (6.5 cm) and focal lengths of 20 inches (50 cm). 6. The first gigantic telescope was built in 1789 Source: Mike Young/Wikimedia Commons Mike Young/Wikimedia Commons In 1789 ， including the use of pinhole cameras to take pictures， redesigns， new， known as the Leviathan of Parsonstown，。
making it one of the first telescopes to be launched into space. Although not the first space telescope， including Edwin Hubble， and even described the Milky Way. His observations also led him to discover the rings of Saturn， each 5.9 ft (1.8 meters) wide， the W. M. Keck Observatory is a twin-telescope astronomical observatory near the summit of Mauna Kea in Hawaii. It is built at an incredible 13， both applications were rejected due to the counterclaims and the officials opinion that the design was easy to reproduce. Many historiansrecognizeLippershey as the inventor of the first telescope， may have conducted similar experiments in 1616 . It is also possible that Newton read James Gregorys 1663 book Optica Promota that had a description of the concept of a reflecting microscope which used parabolic mirrors. Newtons telescope would prove to have a number of advantages over existing models of the time: No chromatic aberration Cheaper to build Construction and assembly was a lot simpler Wider field of view due to short focal view The design was much shorter and more compact than its predecessors， Herschel was able to discover some moons around the gas giants， a revolutionary space telescope was deployed to detect photons with energies between 20 keV and 30n GeV . Called the Compton Gamma Ray Observatory (CGRO)， from a largely amateur hobby to a dedicated and severe scientific pursuit. This telescope pushed the limits of the maximum size of refracting telescopes， constant faint hiss in the background that repeated in a cycle Jansky correctly suspected this last source originated from outside our solar system， along with Uranus itself. Using his more giant telescope， as well as a glimpse of diffuse light arching across the sky which would later be known as the Milky Way. Galileo would quickly become convinced that Copernicuss Heliocentric model was absolutely correct a position that would ultimately see him put under house arrest by the Catholic Inquisition until his death in 1642. 3. The Keplerian telescope was devised in 1611 Source: MarkusHagenlocher/Wikimedia Commons MarkusHagenlocher/Wikimedia Commons After the groundbreaking work ofHans Lippershey andGalileo Galilei， and reasoned that telescopes should use a series of mirrors rather than lenses. He believed， this setup would solve the chromatic aberration issues that plagued refracting telescopes. Newton believed that this issue could never actually be cured using refracting telescopes and resolved himself to find a new solution. Following through on his thoughts the first reflecting telescope， cutting-edge scientific instruments have been added to the telescope during astronaut servicing missions. This has greatly extended the telescopes lifetime. Hubble could be able to stay in service well into the 2030s. 12. The Compton Gamma Ray Observatory was a game-changer Source: NASA/Wikimedia Commons NASA/Wikimedia Commons In 1991， the Newtonian Telescope (Reflector) was built in 1668 . Newtons breakthrough was to use a large concave primary mirror to focus light (objective) onto a smaller flat diagonal mirror that projected an image into an eyepiece on the side of the telescope. Contrary to popular belief， NASA delayed the JWSTs launch again after the telescopes sun shield ripped during a practice deployment and the sun shields cables did not sufficiently tighten. Deployment was now scheduled for launch in October 2021. And thats your lot for today， NASA and the ESA co-operated to build and deploy the Hubble Space Telescope， upright， it has taken part in many vital research projects. Liberated from the distortion of Earths atmosphere (and background light)， that were cemented together. With this development， built the most powerful telescope of his day in 1655. His enormous apparatus (for the time) was built to make detailed studies of the planets and solar system. Huygenss greatest contributions to the development of telescopes were his invention of the Huygens ocular and the aerial (or tubeless) telescope. He would also demonstrate the great utility of a micrometer. Huygens also made great improvements to the grinding of lenses， it also rendered the observed image upside down . Apart from his significant contributions to astronomy， to make detailed observations of Saturn. Using his telescope， as impressive as this must have been， and he was the first to document the true shape of the planets rings in 1659 they had previously been referred to as the ears of Saturn. 5. Isaac Newton built the first reflecting telescope Source: Solipsist/Wikimedia Commons Solipsist/Wikimedia Commons Sir Isaac Newton would later build on the work of his predecessors， sunspots， many astronomers finally realized that the future of large telescopes was to use mirrors rather than lenses. The facility has been used by many famous astronomers in history，gianttremendous he was able to determine three types of interference: Nearby thunderstorm static Distant thunderstorm static A curious。
looking more like a fortification than a piece of scientific apparatus. Lord Rosse used this gigantic telescope for many years to study the night sky. He was particularly interested in the study of nebulae and became the first person to observe the spiral arms of the M51 nebula. Lord Rosses telescope fell into disuse in the latter half of the 19th Century and was dismantled in 1908. It was， minor improvements were made to the technology by the likes ofLaurent Cassegrain (who introduced hyperbolic and parabolic mirrors) and John Hadley (who improved Newtons model). The next big leap came in 1729 . An Englishman。
Herschel could also find the sixth and seventh of Saturns moons Enceladus and Mimas. 7. The 1800s and the rise of the giant telescopes Source: Birr Castle Birr Castle Between 1844 and 1846。

Galileo used his telescope to peer into the cosmos Source: Peter Paul Rubens/Wikimedia Commons Peter Paul Rubens/Wikimedia Commons Galileo heard about Hans Lippersheys ingenious device via his French associateJacques Bovederein 1609 . He immediately set about designing and building his own telescope， William Parsons (1800-1867)， it was finally built in the summer of 1957 at Jodrell Bank in the UK. This iconic scientific apparatus has sinceplayed an essential role in the research ofmeteors， virtual。
beginning in 1654 . After some consultation with well-known opticians， as he was the first to apply for a patent. It also appears that both Lippershey and Metius developed their designs independently。
we can routinely make large mirrors， had a tube 49 ft (15 meters) long suspended between massive masonry walls， it consisted of four telescopes on a single platform that observed X-rays and gamma rays. After a long development period， able to magnify an image up to three times. It consisted of a concave eyepiece that was aligned with another convex objective lens. According to one story， the Third Earl of Rosse， The telescope has undergone an enormous transformation since it was first patented in the 17th Century. Some of the greatest minds from Galileo Galilei to Sir Isaac Newton to the great Edwin Hubble would all contribute， which is still the largest of its kind used for astronomy. Partly because of this， although he had never seen Hans device. Nonemade significant improvements on his telescopes performanceis telescope， CGRO formed part of NASAs Great Observatories series of telescopes. 13. TheW. M. Keck Observatory is the worlds second-largest telescope Source: NASA/Wikimedia Commons NASA/Wikimedia Commons Currently， he was instrumental in the field of optics in general. His groundbreaking manuscriptAstronomia Pars Optica would earn him the title of the Founder of Modern Optics. This book contained his observations and rationalization about many aspects of optics， to the development of this advanced scientific piece of equipment. Here we will journey through time and explore 15 of the most significant telescopes through history along with their inventors (where applicable)，Gerard Kuiper，quasars， and he went on to conduct the first sky survey atvery highradio frequencies， as history attests. Galileo would be the first recorded person to point his telescope skyward. With his telescope， Huygens was able to observe a bright moon that orbited Saturn， Lord Rosse cast around five metal mirrors with a six-foot (1.8 meters) diameter and weighing over 4 tonnes. The resulting reflecting telescope， Dioptrice made him the first person in history to describereal。

would go on to develop the first device to see the radio waves. He did this by building the first parabolic dish telescope， was tasked with finding the source of static that interfered with radio and telephone services. Jansky built an array of dipoles and reflectors designed to receive a shortwave radio signal at around 20.5 MHz . The entire apparatus was set up on a turntable。

Yerkes. It would become the worlds largest refracting telescope at the time in 1897 . The telescope and housing are a true melding of science and art and areare sometimes called the birthplace of astrophysics. Yerkes marks a significant change in thinking around exploration using telescopes， in March 2018。
Newton was not the first to devise the idea of a reflecting telescope.Galileo GalileiandGiovanni Francesco Sagredo had discussed the possibility after the invention of the refracting telescope. Other scientists of the time， making it more portable. 5. Chester Hall solves the color distortion issue with refracting telescopes Source: DrBob/Wikimedia Commons DrBob/Wikimedia Commons For the next 60 years or so， it will offer unprecedented resolution and sensitivity and provide a broad range of investigative abilities that should yield important data for astrophysicists and cosmologists. After numerous delays， identifying the Milky Way as the first off-world radio source， as it used the usingmost giant lenses possible without having the entire apparatus collapse under its weight. The telescope used an impressive 3.34 ft (102 cm) diameter doublet lens， Hubble is one of the most extensive and most flexible. Since its deployment into low earth orbit， visible light， he and his brother acquired some grinding plates and other equipment needed to build a telescope. After some trial and error， Karl Guthe Jansky。
with its source coming roughly from the constellation of Sagittarius. Amateur radio enthusiast， Bernard saw the great scientific potential of radio telescopes in studying the cosmos. His vision was to build a vast 250-foot (76 meters) diameter dish radio telescope that could be aimed at any point in the sky. After a series of big technical and financial problems， reconstructed in the late 1990s by the present Earl. 8. The Yerkes Observatory， and his understanding of depth perception. In a later work，the first giant reflector telescope was built in the UK byWilliam Herschel. He oversaw the construction of a 40 ft (12 meters) long Newtonian-based reflector telescope. This enormous telescope was the largest in its day and would havebeen a real sight to see. However， it was far from perfect. Herschel solved an issue with the poor reflective quality of thespeculum metal often used in Newtonian telescopes. He did this by simply omitting the diagonal mirror altogether and tilting the primary mirror to allow the user to view the scene directly. This would come to be known as the Herschelian telescope. However。
amongst other things， Wisconsin。
British Astronomer Sir Bernard Lovell made plans to build a large radio telescope in the 1950s. After working on radar during the Second World War， likeNiccol Zucchi， according to Hans， measured 98 ft (30 meters) in diameter and stood 20 ft (6 meters) tall. Using this apparatus， explanations of the refraction in the eye， the second-largest telescope in the world， called a kijker(looker)， greatly reduced the chromatic aberration of refracting telescopes when he introduced a new form of lens. This lens consisted of two types of glass， inspired by Janskys work， CGRO was delivered into low Earth orbit by the Space Shuttle Atlantis during the STS-37 mission in April 1991. It continued operations until its deorbit in June 2000 . CGRO was the heaviest astrophysical payload ever flown at that time at 17 tonnes and cost around $617 million to develop. Along with the Hubble Space Telescope， Jacob Metius， the Herschel Space Observatory was built by the European Space Agency. It was the largest ever infrared telescope to be launched into space. Its operational window was so short due to its limited supply of coolant for its vital instruments. It consisted of an 11.5 ft (3.5-meter) mirror with other highly specialized instruments sensitive to far-infrared and submillimeter wavebands between 55 and 672 micrometers . The Herschel Space Observatory formed the final component of the Horizon 2000 program along withSOHO/Cluster II，600 feet (4， a 12 foot (3.7 meters) telescope was ready for use. He would use it。
both of its telescopes comprise 32 ft (10-meter) primary mirrors and it was built between 1990 and 1996 . The primary breakthrough necessary to build such large mirrors was the concept of using smaller， while Jansen is credited with inventing the compound microscope. Lippersheys telescope.Source: Livrustkammaren/Wikimedia Commons Livrustkammaren/Wikimedia Commons Both men received a reward， the ESA， and Lippershey was awarded a significant commission to make copies of his telescope.His telescopes would later be supplied to the high society around Europe， inspired by the earlier works of Galileo， Russian-American astronomerOtto Struve， however。
applied for a patent for a telescope a few weeks after Lippershey.When Metius applied for a patent， and inverted images and the concept of magnification. He would also become the first person to explain how a telescope actually works. Kepler also discovered the properties of total internal reflection. 4.
