The less dense areas were gapped and more spacious, while the dense parts of the sea of gas were being clumped together by gravity. These clumped areas would soon for stars and galaxies. All distant galaxies are slightly red in color, and the redness of the galaxies can reveal how the universe was born. 13.5 billion-years ago the universe was mostly made of hydrogen gas. Hydrogen is the most simplest of gases, but is a tremendous source of power.
How are galaxies created? Some people believe that shortly after the big bang collapsing gas and dust clouds might have lead to the formation of galaxies. Galaxies form only a few hundred million years after the Universe was created. 3. How was Hubble important to our understanding of galaxies?
In a way similar to Earth, the lava planet was formed by gravity forcing broken comets together. Vega’s gravity pulled the planet 75 million miles away from it. A supernova happened right next to the planet, and gold landed in Feuer Leava. Over time, a strange thing occurred. The gold sank into the middle.
Much like Uranus, Neptune’s highly known for its blue coloration, this is explained due to their atmospheric methane; this absorbs light possessing a wavelength analogous to red. Different to Uranus though, Neptune has a much richer blue colour due to another atmospheric component that is currently unknown as of right now that is not in Uranus’. Most of Neptune’s upper atmosphere though includes hydrogen and helium like most other outer planets. Neptune is also akin to Uranus due to their interiors both having two layers: the core and mantle. The mantle is described as an immensely scorching thick liquid made of water, methane, and ammonia.
Neptune, known for its glorious blue color, is 2.7 billion miles away. The nearest star, Proxima Centauri, is 24.92 trillion miles from the Earth. The nearest galaxy to us, the Andromeda Galaxy, is 1.492 times 10 to the power of 19. These distances, as we can see, get so large that astronomers use something called light years. This is the how far light travels in one year.
After flying in the blackness of space for 54.6 million kilometers in just 260 days, we finally approached the red planet. It looked as if I was looking through a telescope from home. Of course, as we got closer, we saw more detail, more craters, and more. Before coming here, I have been able to see many canyons, eclipses, volcanoes, and other things, as well as hearing how geological features on Mars can be taller than Mount Everest, deeper than the Grand Canyon, etc. That is one of the minor reasons why I am here, to see the sizes for myself.
Many people could be given credit for finding Neptune but John Couch Adams and Urbain-Jean-Joseph Le Verrier got most all of the credit. It was the first planet to be discovered by telescope but the first planet to be found by people specifically searching for one. It was launched in August 1977 the spacecraft went to Jupiter in 1979 and Saturn in 1981. After it went there it was programmed to go to Uranus in 1979 and last Neptune in 1989. The data and 10,000 pictures it took increased the knowledge of Neptune majorly.
Nebular Hypothesis is the most widely used theory of how the world became. Most scientists believe that the earth is 4.5 billion years old. The theory of nebular hypothesis says that our solar system consisted of a giant cloud of gas and dust then collapsed. Factors such as heat and pressure caused a big ball and formed a “protoplanetary disc”.
Humanity can now do computer simulations of the universe on a grand scale, and see what happens when certain cosmic events occur. These events are things like the rotation of the planets in our solar system or the orbit of a comet around our sun. The more grand and spectacular simulations see what happens when two galaxies collide. These simulations take the events of hundreds of thousands of years and accelerate it to create a simulation in a matter of minutes. With how technology is exponentially increasing there is no reason to doubt that future computing could do simulations of entire civilizations in hours or even minutes.
