The discoveries of Edwin P. Hubble
The science of astronomy has come a long way. For instance, Galileo discovered the first four moons of Jupiter. Nicolaus Copernicus proved that the Earth wasn’t the center of the solar system. But one man will change all that is known about space. Edwin P. Hubble had discovered a amazing discovery that rocked the whole astronomy community, there were other planets, stars, and galaxies outside of our own. Hubble’s discovery changed everything man has ever known about the stars.
Edwin Hubble changed astronomy community to what it is today with his discoveries. One of them was the discovery of other galaxies from our own. In 1924, Edwin Hubble announced that we are not the only galaxy in space and there are many more galaxies in space. In October 1923 at the Mount Wilson observatory in Los Angeles, California, Hubble proved that the floating gas spirals and circles we saw at night wasn’t just gas but a galaxy filled with stars and planets. He later announced his discovery at a conference in 1924. This discovery changed many concepts on our universe.

Most he divided into two main groups, regular or irregular. In addition, regular galaxies were either spiral or elliptical. Spiral galaxies, like the Milky Way, have huge arms of new stars that trail around a rotating center of older stars. The elliptical galaxies also rotate around a center of older stars, but they are shaped like saucers, lacking the new-star arms of the spiral galaxies (galegroup.com). Hubble’s classifications for galaxies is still used today and has been updated with newer galaxies that have been
Hubble helped determine the age of the universe and the way galaxies are formed. Revealed extraordinary detail about the process by which sun-like stars end their lives as planetary nebulae. The telescope allows to study the universe across a wide swath of the light spectrum structure of the universe and map the distribution of elements fundamental to life. Astronomers believe they formed the most distant objects with Hubble with a Distance of 13.2 billion years away. According to nbcnews.com, Scientist Labb`e stated that previous searches have found 47 galaxies at an adequately later time, when the universe was about 650 millions years old. Hubble has also discovered dark matter. Dark matter is invisible, but reveals its existence via gravity, makes up roughly 23% of the universe. The telescope made it easier to understand how Dark Matter behaves and could help scientist figure out more detail about dark matter. Hubble has greatly expanded astronomers knowledge of the Universe. Before the telescope, distance to far off galaxies were not well known. Hubble’s millionth exposure is of the Planet HAT-P-7b, a gas giant planet larger than Jupiter orbiting a star hotter than our sun. HAT-P-7b, also known as 2b, has been studied by NASA’s planet hunting Kepler observatory after it was discovered by ground- based observations. Hubble now is being used to analyze the chemical composition of the planet’s
This has helped us learn far more about the origins of our Universe and the formation of galaxies from around a billion years after the creation of the Universe, where the galaxies appear to be very shapeless and small, to today where they are larger and formed into spirals or discs. The Hubble Space Telescope has helped pinpoint the age of the Universe to 13.7 billion years22 by studying 31 Cepheid variable stars22, whose fluctuating brightness can be used to calculate their distance thus the expansion and therefore age of the Universe. Knowing the age of the Universe helps astronomers and cosmologists model the Universe and its evolution over its lifetime accurately, which is immensely valuable information to
The Hubble costs about 2.5 billion dollars to make. Also it has 6 cameras and sensors. It was launched in the honor of Edwin Hubble (also why the telescope was named after Edwin). As the telescope goes around in orbit with a light spectrum from the ultraviolet to near infrared it is able to take some very incredibly close and clear images. The telescope uses a digital camera to capture all of the great images and uses radio waves to send the pictures through air back to the Earth so we all are able to see what great things are happening outside of the Earth. With all of the information we get from the telescope we are able to stars being born and stars die. We are able to see galaxies that trillion miles away. It was able to see a comet pieces crash into gases above Jupiter. Also, we have been to discover moons that are around pluto that have never been able to see before. Additionally, we are able to understand how planets and galaxies form. We have so much information and have discovered so many new things from the Hubble Space
Have you ever had a father that swallowed you whole along with your other siblings? Cronus a titan, was that father he was part a big family, he died for eating his kids and he has different things that represent him. Titans back in the day were the first to live before the Olympians.
In 2016 the Hubble space telescope celebrated its 26th year in space. The Hubble space telescope has opened our eyes to the secrets of the universe.
Edwin Hubble was an American astronomer who revolutionized cosmology and was regarded as one of the most significant observers in the field. While working at Mount Wilson, Hubble discovered that there were more existing galaxies besides the Milky Way Galaxy. Hubble took many photos through the observatory's telescope, and it allowed him to calculate the distance of other galaxies by comparing the varying degrees of luminosity in the stars themselves. Although there was no evidence suggesting the size of the other galaxies that Hubble discovered, he was ultimately able to compute that the Andromeda Nebula was about one million light years away from us. Later in his career Hubble began to explore the way galaxies shifted in space relative to
The Hubble Space Telescope is the first major telescope that was placed in space. It has been in operation for over twenty-five years, and has greatly changed our knowledge of the universe. It can observe galaxies and stars that are very far away since it is not blocked at all by light pollution and smog that obstructs the views of the telescopes on Earth. Hubble is fascinating because it was and still is the most revolutionary telescope since Galileo first looked through one over four hundred years ago. Hubble played a large role in helping scientists discover and learn about many things like dark matter and dark energy, the age of the universe, and gamma ray bursts. None of these discoveries would have been possible without Hubble’s unique view of the universe.
The needs for an instrument that would take images of the universe from the space were inevitable since there were so many challenges studying space and the universe from earth. The Hubble telescope, named after the great scientist who confirmed the big bang theory, was the solution to this and it has been in space for the more than 20 years it was supposed to live. Over the time, the telescope has sent home so much information that mankind has realized how little they knew about the universe. This paper covers the needs for the Hubble telescope in space, the impacts that it has had in physics and science and what eventually happens to the telescope when its time expires.
The sky has been observed for centuries, with many great minds pioneering the early devices to see beyond our sky and deeper universe. New discoveries about our universe have impacted our lives and research immensely. It could be said that discoveries in the universe don’t impact our life too much here on Earth, but Quantum Mechanics a field of physics which has been utilizing Hubble’s deep space telescopes in the last couple of decades, is the only reason we have modern computers. The main aims to be investigated are; the impacts of the Hubble Space Telescope, why it has been important, the physics behind it, the cost and problems it has faced. All will be researched and analysed throughout this investigation.
In 1781, an astronomer named William Herschel discovered the planet Uranus, which at the time was the farthest planet known. Herschel was charting stars in the night sky when he noticed a disk in the sky. He started to observe it more and chart the movement. At first, he thought it was a comet, but noticed it was moving too slow. Eventually he figured it to be another giant gas planet which we call Uranus today. This discovery is significant because through it, we know more about our own solar system. Before, we only knew about six planets. Knowing the planets in the solar system has led to more discoveries.
As move through my career and move towards more strategic roles I will be required to consistently influence key stakeholders, who are not within my direct reporting line to achieve results. This is a capability where, if I can master, will directly impact the success of team and businesses I lead in the future.
In this article about a natural satellite in space, talks about how one of the biggest moon's in our Solar System has an ocean 10 times the depth of the earth's oceans, About 100 kilometers thick. This was found on Jupiter’s largest moon called Ganymede by using The Hubble Telescope. They’ve first noticed that the moon’s surfaces was flooding, presumably caused by bubbling up from the interior of the moon which could be cause by cryovolcanoes (or ice volcano), which was soon discovered that the moon’s surface is made out of a thick crust of ice. They’ve discovered this ocean through The Hubble Telescope by monitoring Ganymede and Jupiter's auroras, to see the change in their magnetic field, and they’ve noticed that the moon’s aurora does not
The Hubble’s constant is a measure of the current expansion rate of the universe (1). Researchers have deduced that the expansion rate of the universe is found by the current density and composition it holds (1). Hubble’s constant is represented by H0; the equation use is 1/H0 (1). According to Hubble’s constant, it is around 72 km/sec/Mega parsec (1). Thus, approximately equals to about 13.77 billion years; give or take about 50 million years (1). However, researchers discovered that the universe is currently expanding slower than previous years; affecting the rate of the universe (1).
In The Old Man and the Sea by Ernest Hemingway, the reader is introduced to the plight of Santiago, a very old fisherman who has gone eighty-four days without catching anything. Santiago believes that he will catch a giant fish on his eighty-fifth day of this streak, and gain back his luck. He does catch a fish of over a thousand pounds while at sea over the course of a few days. However, his luck doesn’t last and the giant fish is devoured by hungry sharks while Santiago is on his way back home. This gives readers mixed feelings over Santiago was a winner or a loser at the end of the book, all things considered. Although Santiago was very unsuccessful throughout the story, he was ultimately victorious because he broke his eighty-four day streak of catching nothing, he survived against all odds, and even though it had been ruined, he brought home the biggest fish the town had ever seen.
Once microwave radiation was discovered, studies improved on the Milky Way Galaxy. Its Doppler Shift can be used to map the motion of gas in it. Also, with radio telescopes, hydrogen gas can now be traced. When the Hubble Space Telescope was introduced in 1990, that made exploring space so much easier and more efficient. That’s how we discovered so much about our universe- including galaxies!
