The life and contributions of edwin hubble in astronomy

Edwin was a gifted athlete, playing baseball, football, basketball, and running track in both high school and college. He played a variety of positions on the basketball court from center to shooting guard. In fact, Hubble even led the University of Chicago's basketball team to their first conference title in His studies at the University of Chicago were concentrated on law, which led to a bachelor of science degree in

Its scientific instruments have revolutionized our understanding of the universe and its history, researchers say. A Photo Anniversary ] Those expectations were met. The Hubble Space Telescope reached space with a flawed mirror and initially returned blurry images of the cosmos.

But astronauts fixed the problem during a servicing mission inand Hubble began to produce the beautiful, iconic images for which it is now known. Not long after the fix, Comet Shoemaker-Levy 9 slammed into Jupiter.

Other images of Jupiter revealed unexpectedly low amounts of water in the atmosphere of the gas giant. Hubble also captured images that revealed bright and dark regions on the surface of the dwarf planet Ceres, the largest object in the main asteroid belt between Mars and Jupiter.

Hubble also studied the geology of the asteroid Vesta, which Dawn orbited from July through September New Horizons launched in January and will fly by the Pluto system on July One of the main goals for Hubble was to determine just how quickly the universe is stretching.

The telescope has also provided evidence for the existence of dark energy, the mysterious force that counteracts gravity, causing galaxies to move away from one another at an accelerating pace. By studying special pulsating stars known as Cepheid variables, Hubble helped astronomers nail down the age of the universe with an accuracy of about 5 percent.

The current best estimate is Kite University of California, BerkeleyM. By measuring the sideways motion of the approaching Andromeda galaxy, scientists were able to determine that the two will merge in approximately four billion years.

Mergers are common beyond the Milky Way, as Hubble has shown. When scientists discovered galaxies with long tails of gas and dust — the remnants of mergers — they turned Hubble toward them to reveal details.

The space telescope probed the core of these collisions and uncovered a new class of exceptionally large and bright star clusters. Hubble has helped survey galaxies that existed when the universe was only million years old. Hubble also helped turned a staple of science fiction into science fact.

But Hubble showed that supermassive black holes, which weigh in at millions or billions of times the mass of the sun, exist at the center of most if not all galaxies.

The end of stellar lives By capturing images of a special class of pulsing stars, Hubble helped astronomers to measure the age and expansion of the universe.

These violent blowouts may leave behind black holes or supercompact neutron stars even as they blow the heavy elements that form in the heart of the star through their galaxy. Hubble has helped scientists to better understand the supernova process.

Since it first began photographing the universe, Hubble has captured images of SN A, a supernova that exploded three years before the telescope launched. Hubble has continued to observe the supernova, taking hundreds of pictures to help researchers understand how it has changed over time.

Hubble has also put in time studying the unstable star Eta Carinae, an object that appears to be an explosion in progress. The telescope has allowed scientists to make detailed studies of the structure of the unusual object, including the remnants of the violent outbursts it has experienced for years.

But inHubble captured the first photograph of a planet in orbit around another star, Fomalhaut b. Even before that, Hubble helped to find 16 potential planets orbiting other stars by monitoring the dips in starlight as each planetary candidate passed between its star and Earth.

The instrument has also helped to study the atmospheres of distant planets. Indirectly, Hubble helped to set the stage for Kepler. Hubble revealed billions of stars that were potential planetary hosts, opening up the immensity of the universe.

And putting Hubble into space demonstrated that a level of technological expertise had been met, NASA officials said. Test your knowledge of the telescope in this quiz. This approach has kept the spacecraft operational for a quarter of a century. The last servicing mission in replaced worn parts, and Weiler estimates the craft will keep collecting data for another five or six years.

This story was corrected to say that Hubble has been operational for a quarter of a century, not a quarter of a decade. Originally published on Space.Born in Marshfield, Missouri on November 20, , to father John Powell Hubble and mother Virginia Lee (James) Hubble, Edwin Hubble began reading science-fiction novels at a young Nov 20, Born in Mr.

Hubble became an astronomer later on in life after having a career as a lawyer and fighting in WWI. Mr. Hubble largest contribution to astronomy was . 6 days ago · Edwin Hubble was a highly influential American astronomer who played a crucial role in the development of extragalactic astronomy and observational cosmology.

Edwin is . Edwin Hubble, credited with the discovery of the expansion of the universe, at the Mount Wilson Observatory Credit:: Mt. Wilson Archive, Carnegie Institution of Washington Often lauded as the father of modern cosmology, Edwin Powell Hubble made several significant discoveries that changed how scientists viewed the universe.

Born in Marshfield, Missouri on November 20, , to father John Powell Hubble and mother Virginia Lee (James) Hubble, Edwin Hubble began reading science-fiction novels at a young age. One of his Born: Nov 20, Edwin Hubble went to Oxford University on a Rhodes scholarship, where he did not continue his studies in astronomy, but instead studied law.

At this point in his life, he had not yet made up his mind about pursuing a scientific career.
