For a time, the Hubble telescope was the brunt of jokes and subject to the wrath of those who believed the U.S government had spent too much money on space projects that served no valid purpose. The Hubble was sent into orbit with a satellite by the Space Shuttle Discovery in 1990 amid huge hype and expectation. Yet after it was in position, it simply did not work. Because the primary mirror was misshapen, it was not until 1993 that the crew of the Shuttle Endeavor arrived like roadside mechanics, opened the hatch that was installed for the purpose, and replaced the defective mirror with a good one.
Suddenly, all that had originally been expected came true. The Hubble telescope was indeed the “window on the universe”, as it had originally been dubbed. When you look deep into space, you are actually looking back through time, because even though light travels at 186,000 miles a second, it requires time to get from one place to another. In fact, it is said that in some cases, the Hubble telescope is looking back eleven billion years to see galaxies already forming. The distant galaxies are speeding away from Earth, some travelling at the speed of light.
Hubble has viewed exploding stars such as the Eta Carinae, which clearly displayed clouds of gas and dust billowing outward from its poles at 1.5 million miles an hour. Prior to Hubble, it was visible from traditional telescopes on Earth, but its details were not as certainable. But now, the evidence of the explosion is obvious. The star still burns five million times brighter than the Sun and illuminates clouds from the inside.
Hubble has also provided a close look at black holes, which are described as comic drains. Gas and dust swirl around the drain and are slowly sucked in by the incredible gravity. It has also looked into an area that looked empty to the naked eye and, within a region the size of a grain of sand, located layer upon layer of galaxies, with each galaxy consisting of billions of stars.
The Hubble telescope was named after Edwin Hubble, a 1920s astronomer who developed a formula that expresses the proportional relationship of distances between clusters of galaxies and the speeds at which they travel. Astronomers use stars known as Cepheid variables to measure distances in space. These stars dim and brighten from time to time, and they are photographed over time and charted. All the discoveries made by Hubble have allowed astronomers to learn more about the formation of early galaxies.

До Хаббла это было видно из традиционных Телескопы на земле, но его детали не были как certainable. Но теперь, очевидно, свидетельствуют о взрыва. Звезда по-прежнему горит пять миллионов раз ярче солнца и освещает облака изнутри.Хаббл оказывает также близкий взгляд на черные дыры, которые описаны как комические стоков. Газ и пыль вертеться вокруг умов и медленно всасывается невероятной тяжести. Он также посмотрел в область, которая выглядела пустой невооруженным глазом и в рамках региона размер зерна песка, расположен слой за слоем галактик, с каждой галактики, состоящий из миллиардов звёзд.Телескоп Хаббл был назван Эдвин Хаббл, 1920-е годы астроном, который разработал формулу, которая выражает пропорциональное отношение расстояния между скоплений галактик и скорости, на которых они путешествуют. Астрономы используют звезд, известных как переменные цефеиды для измерения расстояний в пространстве. Эти звёзды тусклым и скрасить время от времени, и они сфотографировали со временем и наметили. Все открытия, сделанные Хаббла позволили астрономам узнать больше о формировании раннего галактик.
