Planetary Disorders: The Solar System

Stars are the most recognized astronomical object in space and they represent the building blocks of galaxies. Stars distribute elements such as: carbon, nitrogen, and oxygen. A star develops from a cloud of hydrogen and helium, the dust clouds that are scattered throughout galaxies. An example of a dust cloud is the Orion Nebula. The gas and dust begin to collapse from its own gravitational pull. As the cloud collapses, the middle gets hotter. This is known as a prostar. A dense and hot core forms which begins to collect dust and gas. All this material may not end up as a part of the star but can become planets, asteroids, comets, or remain dust. A star about the size of our sun can up to 50 million years to mature. The smallest stars are

The cloud would spin around space. A nearby star had exploded causing the cloud to shrink. A mass formed in the middle of gas. The mass became known as the Sun. Gas and clouds around the Sun created whirlpools. As the whirlpools spun it created masses around the Sun. This became known as the planets, which created the Solar System.

In the nebular hypothesis, the solar system started out as a cloud. The cloud of gas cooled and shrank into a sphere. The law of conservation of angular momentum caused the sphere to spin faster. Centrifugal forces caused some of the matter to fly off of the sun. This matter formed a ring around the sun. The matter that was originally a part of the sun cooled and condensed into the planets. One problem with the nebular hypothesis is that an unreasonably large amount of gravitational pull would be needed to condense the rings of matter into planets. Also, the Sun, although containing most of the mass in the solar system, has only a small fraction of the angular momentum.

A: The the reason why the clouds begin to spin faster was because of the things that we call angular momentum. We don't know or we know that the the change in shape will affect the speed of rotation however the mass will stay the same. So as the cloud continue to compress in order to conserve the angular momentum the nebula began to speed up. This speeding up allowed for the cloud to leave behind little particles of dust and gas that would later form our planets.

Approximately 1,000 years ago the pattern of mass loss suddenly changed, and the Cat's Eye Nebula started forming inside the dusty shells. It has been expanding ever since, as discernible in comparing Hubble images taken in 1994, 1997, 2000, and 2002. The puzzle is what caused this dramatic change? Many aspects of the process that leads a star to lose its gaseous envelope are still poorly known, and the study of planetary nebulae is one of the few ways to recover information about these last few thousand years in the life of a Sun-like

The meteor is thought to have flash melted the crust which proceeded to differentiate into a granophyre and a leuconorite to norite composition. The granophyre makes up 60% of the complex and the leuconorite and norite make up the remaining 40% (Figure 1b)(Barnes et. al., 2005). About 50% of the ore is found in the sublayer norite and the breccia that is associated with the norite. This ore is mainly disseminated sulphides. The massive sulphides are located in the center

was forming it was a giant ball made of liquid molten. Over a long period of time asteroids hit

when a star explodes as a supernova most of its matter is blow away into space .Is a star with a initial mass of 0.5 to 8 times that of earth’s sun .it spends most of its time on the main sequence as an orange ,yellow or blue dwarf star.all stars are little clouds of gas .it begins to collapse under its own gravity .This star is made by when the sun shucks off its outer layers it will create a beautiful shell of diffuse gas known as planetary nebula .The first planetary nebula with was discovered with a bright in 1790 .These stars are made up of dust or gas.New technology has captured a number of phenomenal images of planetary nebula in extreme depth .where scientist thought that the gaseous layers came off evenly , images from the hubble space telescope have revealed a wide array that it could be the fate of our closest star . These stars are born just like average

Throughout the universe, there are dense molecular or dust clouds, known as interstellar clouds, and they are the first stage of a star. These clouds are incredibly large, containing thousands of times the mass of the Sun, and while they start out stable, for them to one day become a star, they must become unstable. Once this happens, they are no longer able to withstand their own gravity and they break into smaller pieces. The trigger for these events are still unknown, but astronomers think it is caused by some external event that forces the cloud to the next stage: cloud fragments.

As the cloud spins, it gets hot in the core of the nebula. When the core is hot, the outer layer of the planetary disc is mostly colder, and that’s what occurred in the shape. The hot part of the cloud is made up of dust and gas while the outside is colder and icier. The more the nebula spun, the thinner it developed. All of a sudden, masses made up or small particles got close to the shape and the particles created the planets

One of the mysteries scientist are trying to figure out in Antarctica is how the solar system formed. One of the clues scientists study to learn about the solar system is meteorites. Meteorites is a rock that have come from space and landed on earth. Meteorites are easy to find in Antarctica because the continent is covered in white and blue ice. Meteorites have an uneven and glossy surface, and they are dark, so they contrast with the snow and ice. Some of the Meteorites found in Antarctica

All these speculations were only based on theories made by many scientists and apparently it began 4.6 billion years ago with the gravitational collapse of small part of a giant molecular cloud. Apparently the small collapsing mess collected in the centre and formed Sun, while the rest flattened into a proto planetary disk out which the planets, moons, asteroids and other small solar system bodies formed. This idea of the solar nebula was first formulated by the Prussian philosopher and physicist Immanuel Kant in 1755 and this idea to the problem was only qualitative because it was similar to those taken fundamental today. This model was first developed in the 18th century by these scientist Emmanuel Swedenburg, Immanuel Kant and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology and planetary science. Since the dawn of the space age in the 1950s and the discovery of extrasolar planets in the 1990s, the model both challenged and refined to account for new

The first thing you might be wondering is, what exactly is a nebula? Well according to Franknoi, a nebula is “A cloud of interstellar gas and dust that can be seen to glow with visible light or invisible light” (Franknoi 532). The Carina Nebula was formed approximately 3 million years ago in the Southern region of the Milky Way in the Carina constellation. It is located roughly 7,500 light years away from earth, which is relatively close in special terms, and even bright enough to be seen from south of the earth’s equator. It was discovered by French astronomer, Nicolas Louis de Lacaille, in 1751 from the Cape of Good Hope in

Galileo’s thoughts addressed the first recent theories about the emergence of Nebulae in his book Assayer. Here he mentions nebulae to be composed of different distant stars but he did not believe it to include clouds and other particles. Eventually at a later point a catalogue of 103 Nebulae was published by Charles Messier. Although Messier’s actual interest were comets he was one of the first to discover Nebulae’s
