Description: Stonehenge is an astronomical observatory in which observations where made about Earth rotating the sun, the motion of the stars, moon, and sun, and the variations of brightness by planet. The first model of the solar system was created based off ancient observations made at Stonehenge.

Description: Claudius Ptolemy was a Greek astronomer who created the Ptolemaic solar system model to accurately explain planetary motion and claim that the Earth was at the center of the universe. Ptolemy also released a star catalog named the Almagest in where he recorded the brightness and position for over 1,000 stars. ]]> 2020-02-20 15:37:37 UTC https://padlet.com/lozamar016/aa4zear357ii/wish/448092928 lozamar016 https://padlet.com/lozamar016/aa4zear357ii/wish/448610040 Location: Poland, Europe
Description: Nicolas Copernicus created the model of the heliocentric solar system which emphasized that the sun was at the center of the solar system while planets and the moon orbited around it while at the same time the moon and the Earth spin on their own axis. At the time his heliocentric model was against religious beliefs.

Description: Galileo Galilei was an Italian mathematician and philosopher who built his own telescope once he heard of the invention. With the telescope, Galileo made astronomical observations claiming in his published work that there was sunspots on the sun, he discovered Jupiter's four "Galilean" moons, and he came forward to support the heliocentric model. Because of this he was jailed.

Description: Tycho Brahe studied many things among astronomy, alchemy, and medicine in his own observatory with his own equipment. Brahe recorded very detailed and accurate notes on stars planets and even a comet and a supernova. His accurate and detailed notes on the positions of celestial bodies helped create the law of planetary motion.

Description: Johannes Kepler was a German astronomer and mathematician who used Brahe's recording to find a simple description of planetary motion. Kepler is mostly known for the three laws on planetary motion that he created.
1st Law - with the sun being the focus, the orbital paths of planets around the sun are elliptical and NOT circular
2nd Law - Law of area: an imaginary line connecting the sun to a planet "sweeps out equal area in equal time"
3rd Law - “The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit”

Description: Isaac Newton was a physicist and mathematician mostly known for creating the term gravity and creating the law of universal gravitation, and also developing three laws of motion.

Description: Albert Einstein was a German physicist who published ground breaking research on quantum mechanics, and theories about gravity and motion, including his special relativity and general relativity theory. ]]> 2020-02-21 15:06:52 UTC https://padlet.com/lozamar016/aa4zear357ii/wish/448620728 lozamar016 https://padlet.com/lozamar016/aa4zear357ii/wish/448621067 Location: Cambridge, England
Description: Stephen Hawking was a British theoretical physicist who did research on black holes contributing to the relativity theory and quantum mechanics. He proposed that black holes emit subatomic particles until they eventually explode. ]]> 2020-02-21 15:07:15 UTC https://padlet.com/lozamar016/aa4zear357ii/wish/448621067 lozamar016 https://padlet.com/lozamar016/aa4zear357ii/wish/449049657 Location: Greece- Turkey
Description: Hipparchus was a Greek astronomer credited as the founder of trigonometry but most importantly known for discovering the procession of the equinoxes. He also is the first person to accurately measure the distance between the moon and the Earth and he discovered the star Nova. ]]> 2020-02-22 23:02:42 UTC https://padlet.com/lozamar016/aa4zear357ii/wish/449049657 lozamar016 https://padlet.com/lozamar016/aa4zear357ii/wish/449051168 Location: The earliest known telescope invented appeared in the Netherlands, created by Hans Lippershey
Description: Hans Lippershey who was a Dutch eyeglass maker is credited as the first man to invent the telescope in 1608 because he was the first person to have permission to redistribute the telescope. Lippershey claimed his telescope zoomed in to objects up to three times.
Shortly after hearing about Lippershey's invention, Galileo created his telescope in 1609 and improved it by making its magnification reach up to 20 times.
In 1611, Johannes Kepler also made his improvements to the telescope when he created the Keplerian telescope, a refracting telescope.
In 1668 Isaac Newton created the first reflecting telescope, using a series of mirrors.
In 1729 Chester Hall solved the issue about color distortion in refracting telescopes.
In 1789 the first giant refracting telescope was built in the UK by William Herschel.
In 1937 the first radio telescope was built. 
IN 1990 both NASA and ESA built and launched into space for the first time the Hubble space telescope.
In may 2020 NASA and ESA have scheduled to launch into space a newly developed telescope, the James Webb Space Telescope to replace the aging Hubble Space Telescope.
