In this cloud, there will be regions that are less dense and more dense (Sagan, 2015). The less dense particles are pulled towards the denser region because of gravity (Sagan, 2015). Then as the center of this cloud condenses (Sagan, 2015). The entire cloud will start to rotate faster and faster due to the conservation of angular momentum, which is the idea that as the mass of an object increases, the speed of an rotating object must also increase (Sagan, 2015).

As more and more matter collides with the nucleus, the temperature of the cloud will continue to rise (Sagan, 2015). After millions of years, the temperature of the center of the cloud will reach about 15 million degrees (Sagan, 2015). At this temperature, the center of the cloud will form a star (Sagan, 2015). If the cloud is still moving at a decently fast pace, the star will separate into a star system or a group of stars (Sagan. 2015).

With the formation of these stars, there are still large dust clouds that are rotating around the star (Sagan, 2015). In denser areas of the cloud, nearby matter is attracted and planets start to form in these denser regions (Sagan, 2015). During the formation of planets, heavier elements sink to the center of the planet, leaving hydrogen and helium as the atmosphere surrounding the planet (Sagan, 2015).

Some planets don’t have atmosphere since the star’s radiation pressure blows away this atmosphere (Sagan, 2015). Other times, planets are able to retain their atmosphere (Sagan, 2015). Since the planets formed consists of mostly hydrogen, it must also contain hydrogen compounds (Sagan, 2015). The most abundant are hydrogen compounds of carbon, nitrogen, and oxygen (Sagan, 2015).

These hydrogen compounds include methane, CH4, ammonia, NH3, and water vapor, H20 (Sagan, 2015).

The basic elements in planets result in possible formation of life. The “six main elements associated with life on Earth (include): carbon, nitrogen, oxygen, phosphorus, sulfur and hydrogen (“Exoplanet Exploration: Planets Beyond Our Solar System: Life Signs.” 2017).

When hydrogen, methane, ammonia, and water vapor; which are the elements and compounds that are noted earlier; are mixed together with supplied energy, organic compounds are produced (Sagan, 2015). The compounds produced are usually amino acids, which are the main building blocks for proteins and nucleic acids (Sagan, 2015). Amino acids lead to the formation of purines and pyrimidines, which form into nuclei.....[read full text]
