However, the work of modern astronomers rests largely upon the discoveries and insights of previous generations of scientists, so in this list, we will take a closer a look at the ten most important astronomers of the last several hundred years, in chronological order.

The top 20 astronomers

Famous astronomers — many of them great scientists who mastered many fields — explained the heavens with varying degrees of accuracy. Over the centuries, a geocentric view of the universe — with Earth at the center of everything — gave way to the proper understanding we have today of an expanding universe in which our galaxy is but one of billions.

On this list are some of the most famous scientists from the early days of astronomy through the modern era, and a summary of some of their achievements. Any list of famous astronomers has to include a varied collection of great scientists from the Greeks to the modern era, big thinkers who tackled many fields as well as modern astronomers who The top 20 astronomers significant discoveries and helped popularize astronomy.

Bartolomeu Velho, Public Domain When most people believed the world was flat, the notable Greek mathematician, astronomer and geographer Eratosthenes — B. His measurement of 24, miles 39, kilometers was only miles km off the true measurement. In ancient Greece, astronomer and mathematician Claudius Ptolemy A.

Known as the Ptolemaic system, it remained in place for hundreds of years, though it turned out to be flat wrong.

Public Domain In 16th century Poland, astronomer Nicolaus Copernicus — proposed a model of the solar system that involved the Earth revolving around the sun. Using detailed measurements of the path of planets kept by Danish astronomer Tycho BraheJohannes Kepler — determined that planets traveled around the sun not in circles but in ellipses.

In so doing, he calculated three laws involving the motions of planets that astronomers still use in calculations today. Talk by astronomers of a sky filled with objects moving in non-circular orbits and other phenomena that went against an Earth-centric model threatened their beliefs.

As a result, Kepler and his first wife, Barbara, created a code with which to write letters to each other so that their correspondence would not put them at risk of persecution. NASA Born in Italy, Galileo Galilei — is often credited with the creation of the optical telescope, though in truth he improved on existing models.

He created a telescope later that same year that could magnify objects twenty times. Though a model of the Earth circling the sun was first proposed by Copernicus, it took some time before it became widely accepted.

Galileo is most widely known for defending the idea several years after Kepler had already calculated the path of planets, and Galileo wound up under house arrest at the end of his lifetime because of it.

Italian astronomer Giovanni Cassini — measured how long it took the planets Jupiter and Mars to rotate. Dutch scientist Christiaan Huygens — proposed the earliest theory about the nature of light, a phenomenon that puzzled scientists for hundreds of years.

English astronomer Sir Isaac Newton — is most famous for his work on forces, specifically gravity. Edmond Halley — was the British scientist who reviewed historical comet sightings and proposed that the comet that had appeared in,and were all the same, and would return in Although he died before its return, he was proven correct, and the comet was named in his honor.

French astronomer Charles Messier — composed a database of objects known at the time as "nebulae," which included objects at its final publication, though additional objects were added based on his personal notes. Many of these objects are often listed with their catalog name, such as the Andromeda Galaxy, known as M Messier also discovered 13 comets over the course of his lifetime.

British astronomer William Herschel — cataloged over 2, deep sky objects. William trained his sister, Caroline Herschel —in astronomy, and she became the first woman to discover a comet, identifying several over the course of her lifetime.

Henrietta Swann Leavitt — was one of several women working as a human "computer" at Harvard College, identifying images of variable stars on photographic plates.

She discovered that the brightness of a special flashing star known as a Cepheid variable was related to how often it pulsed.

These astronomers are among the most prominent in their field, and. Kepler has catalogued over 4, exoplanet candidates, including in the habitable zone. Now, researchers have analyzed data and narrowed the list down to the 20 best candidates for habitable. In , the organization responsible for classifying celestial bodies, the International Astronomical Union (IAU) decided that a new class of objects was needed. Pluto, considered a planet since its discovery in , was reclassified into the new “dwarf planet” category. To date, five dwarf.

This relationship allowed astronomers to calculate the distances of stars and galaxies, the size of the Milky Way, and the expansion of the universe. Albert Einstein at the blackboard.

NASA In the early 20th century, German physicist Albert Einstein — became one of the most famous scientists ever after proposing a new way of looking at the universe that went beyond current understanding.

Einstein suggested that the laws of physics are the same throughout the universe, that the speed of light in a vacuum is constant, and that space and time are linked in an entity known as space-time, which is distorted by gravity. In a lecture given infellow scientist Robert Oppenheimer said, "Einstein was a physicist, a natural philosopher, the greatest of our time.

Prior to his observations, the discussion over the size of the universe was divided as to whether or not only a single galaxy existed.List of notable or famous astronomers from the United States, with bios and photos, including the top astronomers born in the United States and even some popular astronomers who immigrated to the United ashio-midori.com you're trying to find out the names of famous American astronomers then this list is the perfect resource for you.
