The U-EL license is applied only for the staff of the organization that holds the account. It is an additional license to the usage included within the regular Royalty-Free / Editorial license that awards rights for a single person within the same company. It has allowed for more precise calculations of the age of the universe, shown galaxies in all stages of the universe, and played a key role in the discovery of dark energy, the force causing the universe to expand.This license extends our regular Royalty Free / Editorial license to an unlimited number of seats within the same organization. The telescope, named for Edwin Hubble, has provided a wealth of information about the cosmos, transmitting hundreds of thousands of images. In 1990, 101 years after Hubble's birth, NASA launched the Hubble Space Telescope into orbit around Earth. Since the Nobel Prize cannot be awarded posthumously, Hubble was ineligible. Unfortunately, it didn't happen until 1953, the year Hubble died. Hubble labored in vain for a change that would allow astronomers such as himself to be recognized. During his lifetime, astronomy was considered a field of physics for the world-renowned Nobel Prize. But he never received the Nobel Prize, despite his role in improving the existing understanding of the universe. Though Hubble is most well known for these major discoveries, he also made a number of other contributions to the field of astronomy, and received numerous awards. After Hubble had shown the universe was, in fact, expanding, Einstein visited him at Mount Wilson, calling his decision to change the equations, "the greatest blunder of my life." A lifetime contribution But Einstein removed the equations because they contradicted the evidence of the day. Over a decade before Hubble published his work, renowned scientist Albert Einstein's theory of General Relativity called for an expanding universe. According to the calculation, the universe is expanding at a constant rate, known as the Hubble constant. ![]() The calculation to determine the rate at which the universe is expanding is known as Hubble's law, though it was originally proposed by Georges Lemaître in 1927. Astronomers rushed to test his calculations on other galaxies, and found that some were moving as quickly as 90 million mph (40,000 kilometers per second) in the opposite direction. Instead, virtually every galaxy seems to be rushing away from Earth (the Andromeda Galaxy is instead rushing toward us and will collide with the Milky Way in about 5 billion years). ![]() In studying the various galaxies, Hubble was able to determine that they did not sit stationary in space. Hubble originally thought that galaxies evolved from ellipticals to spirals, but scientists now know that each galaxy's shape is determined in its early life. Known as the “tuning fork” diagram (due to its resemblance to that musical piece), the method organizes ellipticals by their ellipticity (how stretched out they are from a perfect circle), while spirals and barred spirals become less tightly wound as they progress. Hubble's clear method of organizing the various classes focuses on three galactic types: ellipticals, spiral and barred spirals, and irregulars. At the time, a descriptive system existed, and two other systems were proposed soon after, but they were insufficient. Around the same time, Hubble published a standard classification system to use for the galaxies.
