First Binary Pulsar Research Paper

“classified Hubble as a Cassegrain reflector, who was among the first to suggest a basic optical design.”1 The Hubble space telescope was launched and deployed in April of 1990, which “marked the most significant advance in astronomy since Galileo's telescope. Thanks to four servicing missions and more than 25 years of operation, the view of the universe and humanity's place within it has never been the same.” 2 In describing how

Luis Walter Alvarez was born on June 13th in the year 1911 in San Francisco but at that time no one knew he was going to be a world renowned physicist. As a adolescent, his love for science, technology and machines was evident, but no one guessed he would make something out of it. He and his father (Walter C. Alvarez) built a radio when he was eleven, this was when the radio was still a new invention. Graduating from The University of Chicago in 1932 and earning his phD in 1936 was not the end of his scientific interest. Luis Walter Alvarez continued to study science and physics. He was credited with many necessary discoveries about subatomic particles for which he earned the Nobel Prize in physics. His work did not stop there. He was a co-developer in the creation of the “ground-control approach system” for aircraft during the 1940’s. Luis Walter Alverez had a very significant role in the development Manhattan Project, in which he suggested the technique used for the detonation of an atomic bomb. He was member of the National Inventor's Hall of Fame. On top of all this he held ownership of the patents for over 30 inventions including radar systems and the bubble chamber.

The discovery of the heliocentric model

In March of 1781 William Herschel, a musician and amateur astronomer discovered what would eventually be called “Uranus.” He discovered what he initially thought was a comet, while looking for what he called double stars. He ended up finding Uranus as it passed by one of the stars he was looking at. He recorded is in a journal, and after a few days looked for it again. He was able to see that it was moving and that it appeared to have an orbit. He contacted some friends of his that were astronomers and gave them the work that had done and wanted to them to explore it further than he could. They ended up finding the same thing and also classifying it as a comet, probably a comet called 1770, and congratulating him on his discovery. It wasn’t

This allowed, for the first time, to accurately determine Pluto’s mass and diameter (Putnam). However, during this time, even the U.S. Naval Observatory Flagstaff Station located on the outskirts of town was being taking over by the overpowering monster of light emanating from city streets.

William Herschel was a musician and an astronomer. The motivation that drove William Herschel to the discovery of Uranus was his obsession with astronomy and the heavens. He charted the stars with a telescope he built himself, he then discovered a “comet” which really was the planet Uranus, but he initially didn’t realize it. He noticed the “comet” had moved and decided that his annotations on the position of the “comet” had been written down incorrectly. Herschel wanted to know the dimensions, and position of the “comet”. He carefully measured the location and diameter of the comet for some time and discovered its journey as parallax to “our side of the sun” on a daily basis. In 1782 Herschel finally called the comet his planet. The knowledge

The moons we know today were also discovered by Herschel: Titania and Oberon. After two years, in 1789 William also finished his largest telescope, 48 inches. This telescope made another Saturn’s sixth and sevenths moon; Enceladus and Mimas. Now moving on from the telescope, William tried out a basic experiment determining the temperature of different colors passing through a prism. He began to notice light that was beyond the color red. Higher then light and the visible spectrum. Using measurements and prior knowledge the light he was seeing is what we know today, Infrared radiation. The European Space Agency infrared space observatory was subsequently named for him.

William Herschel was an astronomer and telescope maker. It was through one of his telescopes, in March of 1781, that he discovered Uranus. Initially he believed, as other astronomers of his day, that Uranus was a comet. As he continued to observe the planet over the next four days he came to the conclusion that the planet did not have the same motion as a comet. After months of observation, he was able to chart its orbital path which would double the size of the known solar system at that time. Because of William Herschel’s discovery he opened up the heavens with his proof that there was much more to our solar system than was believed at that time. William Herschel discovered more that Uranus, he gave shape to the Milky Way, he discovered

Frederick William Herschel was a British astronomer and composer. In 1774 he constructed his first telescope with which he spent the next 9 years studying the sky. After the completion of several catalogues, on March 13, 1781, he made an amazing discovery. The planet Uranus. This was an extraordinary discovery, and because of it, Herschel was made Court Astronomer by King George the Third, which was indeed a great honor. Later on he became the first President of the Royal Astronomer Society, in 1820. One of the key people leading to his Astronomy breakthroughs was Reverend John Michell, who was making ground-breaking views on astronomy and the construction of telescopes. Michell and Herschel met, as Herschel was a composer, and Michell was

Elizabeth Gibney discusses the history of fast radio bursts and astronomer’s strategy to finding them in the universe in her article, “Fast Radio Bursts are Astronomy’s Next Big Thing.” She begins by defining fast radio bursts as “fleeting blasts of energetic cosmic radiation of unknown cause.” (Gibney) Gibney briefly reviles that even though FBRs were discovered a decade ago, the phenomenon has just recently been accepted as genuine.

William Herschel had a telescope and he loved searching the universe anything. He also had a sister that also searched the galaxies and enjoyed gazing into the night sky with a new perspective. On the night of Tuesday March 13, 1781 Herschel saw Uranus for the first time, even though he didn’t know it, yet. According to the article “Managing Expectations” written by Krupp he informs us that the first-time William saw Uranus he actually thought it was a comet. “Uranus was the first new planet to be found since antiquity, but at the outset it was not at all clear that a new world had been spotten. Herschel’s telescope provided the world’s best view of the new object, but even Herschel thought he had discovered a comet. (Krupp)” Herschel had to

The study of pulsars began when Antony Hewish and his students at Cambridge built a primitive radio telescope to study a scintillation effect on radio sources caused by clouds of electrons in the solar wind. Since the telescope was designed to record rapid variations in signals, in 1967 it recorded an unexpected source. Jocelyn Bell Burnell noticed a strong scintillation effect opposite the sun, where the effect should have been weak. An improved recorder was installed, the signals were received again as a series of sharp pulses with intervals of about a second. In 1968 it was clear that the team discovered a rapidly spinning neutron star, a remnant of a

The discovery of Uranus on March 13th in 1781 by William Herschel was an accident. He was using his 7ft reflector telescope. He had talked to Joseph Priestly and John Mitchell about the construction. It started as a survey of the stars to “isolate as many double stars as he could discover”. When he spotted Uranus he thought it was a comet.

Planets have mass and therefore have an effect on their stars orbit causing it to wobble. The wobble in the case of a pulsar star is seen as the periodic delay in the arrival of the pulses from the pulsar star (Wolszczan 1994). Due to the nature of a Pulsar star we can detect perturbations in its orbit through its pulses but to detect perturbations in other stars orbits, astronomers use a stars radial velocity.
