It was the first comet ever predicted to return. English astronomer and mathematician Edmond Halley was born near London, England, years ago today. The 17th century was a very exciting time to be a scientist in England. The scientific revolution gave birth to the Royal Society of London when Halley was only a child.

Members of the Royal Society — physicians and natural philosophers who were some of the earliest adopters of the scientific method — met weekly. The first Astronomer Royal was John Flamsteedwho is remembered in part for the creation of the Royal Observatory at Greenwichwhich still exists today.

Halley had the chance to visit him in his observatory on a few occasions during which Flamsteed encouraged him to pursue astronomy. Halley thought he would do the same, but with stars of the Southern Hemisphere. His journey southward began in Novembereven before he obtained his university degree.

He sailed aboard a ship from the East India Company to the island of St.

Helenastill one of the most remote islands in the world and the southernmost territory occupied by the British. His father and King Charles II financed the trip.

Young scholar

Of the transit, he wrote: This sight … is by far the noblest astronomy affords. Mercury is the small black dot on the left side the sun, in this image. See more photos of the Mercury transit. No one had ever attempted to determine the locations of southern stars with a telescope before.

In the same year, he received his M. A from the University of Oxford and was elected a fellow of the Royal Society. Halley visited Isaac Newton in Cambridge for the first time in A group of Royal Society members including physicist and biologist Robert Hookearchitect Christopher Wren and Isaac Newton were trying to crack the code of planetary motion.

Halley was the youngest to join the trio in their mission to use mathematics to describe how — and why — the planets move around the sun. They were all competing against one another to find the solution first, which was very motivating. Their problem was to find a mechanical model that would keep the planet orbiting around the sun without it escaping the orbit or falling into the star.

Hooke and Halley determined that the solution to this problem would be a force that keeps a planet in orbit around a star and must decrease as the inverse square of its distance from the star, what we today know as the inverse-square law.

Hooke and Halley were on the right track, but they were not able to create a theoretical orbit that would match observations, in spite of a monetary prize to be given by Wren. The Royal Society decided that Halley should edit the Principia and finance its printing.

Halley is also known for his work in meteorology. He put his talent of giving meaning to great amounts of data to use by creating a map of the world in The map showed the most important winds above the oceans.

It is considered as the first meteorological chart to be published. Halley kept travelling and working on many other projects, such as attempting to link mortality and age in a population.

This data was later used by actuaries for life insurance. He became a professor of Geometry in Oxford in The following year, he published A Synopsis of the Astronomy of Comets. The book contains the parabolic orbits of 24 comets observed from to He noted they were so similar that they must be in fact one comet, which returns periodically every 76 years.A comet is a celestial object which consists of ice and dust.

when a comet nears the Sun, its heat melts some of the ice, which creates a “tail” in the comet. Halley elliptically orbits around the Sun in between the orbits of Mercury and Venus. Edmund Halley was an accomplished astronomer.

His work led to the discovery and confirmation of the orbit of P/1 Halley, the comet that bears his name. Full Name: Edmond Halley Nationality: English Profession: Astronomer, Mathematician and Physicist Why Famous: Edmund Halleys' reputation mainly rests on his discovery of the orbit of Halley's Comet, named after him but he was widely involved in a number of scientific endeavors.
