Gas Cloud Research Paper

Scientists are not certain how the universe evolved after the big bang. Many believe that as time passed and matter cooled, more diverse kinds of atoms began to form, and they eventually condensed into the stars and galaxies of our present universe, (Borner, 1993). Planets may have formed as a result of a supernova blast. Planets that existed before the supernova were destroyed. Any planets that had survived the explosion were left behind as free-floating objects. Planets found around pulsars, remnants of the supernova explosion, formed as a result of pre-existing stellar companions. In addition, planets may form in an accretion disk of fallback matter surrounding a pulsar, (Williams, 2014).

Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,

The life cycle of the Sun starts like all stars with a cloud of dust and gas made up of mostly hydrogen. If the cloud cools, it will shrink because of the gravitational pull between the particles

The amazing amount of radiation coming from the disk of gas is ripping the galaxy apart.

As our proto-sun was forming and spinning gases such as hydrogen and helium were pushed to outer rings of the nebula. Dust grains near the sun started to collide and overtime the particles and the collisions grew larger. Furthermore, gravity pulled these some of pieces together at a faster rate and over time this process created small planets or planetesimals . As these planetesimals grew larger they combined and created the planets closest to the sun : Mercury, Venus, Mars and Earth.

When the sun was a young star, the leftover material formed what would be planetary disks. These are accounted by all the planets in the solar system. Venus was made into the second planet from the sun. Over the next billion years the planet formed. There

The Sun,Mars, and most other planets are spinning counter-clockwise. 4.54 billion years ago, our Solar System was forming within a cloud of hydrogen not unlike any other Nebula. It must have got a kick from a supernova. The gravity continued to grow stronger until it collapsed from the force. The cloud began to spin because of the gravity. But why is that? The reason is because of inertia, the effect of an item of matter not changing without an outside force. Since there is nothing

It started five billion years ago as a cloud of dust and gas about 10 billion kilometers in diameter that rotated slowly in space. This massive cloud shrank over time because of its own gravitational pull, or because of an exploding passing star. Most material collected in the center and it rotated faster as it shrank. Compression of the material made it hotter, which started hydrogen fusion, forming the sun. Ten percent of the material in the cloud formed a disk around the sun. Due to friction in the disk, most of the mass collected into whirlpools. These whirlpools shrank to form protoplanets. These protoplanets became planets and moons. Excess material became comets, asteroids, and meteoroids. A problem with this hypothesis is that it would be unlikely for a passing star to explode, because stars are very far apart from each other. Also, as with the nebular hypothesis, it would take an unreasonable amount of gravitational pull for the disk to condense into

Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.

Gravity drew dust and gas together to create the solar system. The sun formed first from the material closely by the planets. Waves of energy traveling through space pressed clouds of such particles closer together, and gravity causes them to collapse in on themselves. As the material drew together, gravity caused it to spin. The spin caused the cloud to flatten into a disk like a pancake. In the centre, the material clumped together to form a protostar that would eventually become the sun. The protostar was a ball of hydrogen and helium not yet powered by fusion. Over the course of 50 million years, the temperature and pressure of the material inside increased, jumpstarting the fusion of hydrogen that drives the sun today. (Credit, 2016)
