Edwin Hubble's The Realm Of The Nebulae

Looking up at the vast sky with the naked eye, one can see a beautiful display of stars, planets and the Moon. However, the Earth’s atmosphere distorts and blocks electromagnetic radiation, making it impossible for terrestrial telescopes to observe objects, in space, clearly. In his conclusion of The Realm of the Nebulae, Edwin Hubble describes the limitations of space exploration,

“With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation” (202).

Scientists have pushed the boundaries of technology by pioneering new ways and overcoming the limits beyond their comprehension of the universe. Since the invention of the Galilean telescope over 400 years ago, the development and implementation of the Hubble Space Telescope has proven to be astronomies’ most significant achievement designed to unlock the

His correlations between the redshift of faraway galaxies in relationship to their distance from Earth led to the rate of the universe’s expansion, known today as Hubble’s constant. A team of scientists have used the Hubble Space Telescope to show that the universe is expanding at a rate five to nine percent faster than once thought (STScl). Using Hubble’s Wide Field Camera 3, the team has been able to calculate distant dimensions much more precisely. Before the launch of the Hubble, in 1990, Hubble’s constant varied by a factor of two, however, the data from the HST has brought the redefined value within an error of only 10 percent (STScl). These scientists continue to find ways to improve the accuracy of their measurements as they navigate to the outer depths of
