Nebulae Research Paper

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

This however, is far from the truth. Previously it was believed that the dark areas in the sky were just blank spaces between the stars, however it is now known that these “blank spaces” aren’t so blank after all (Koupelis p.367). Astronomers have discovered that they are in fact large clouds of dust, or interstellar dust to be precise, that instead block out the light from the stars behind it (Koupelis p.367). The term nebula has its origin in the adjective nebulous, which means “lacking definite form or limits” (Koupelis p.370). Much like the clouds that we see here on Earth, nebulas also come in all shapes and sizes. Per scientists, nebulas are defined as being an interstellar cloud of dust, hydrogen, helium, and other ionized gases (Wikipedia). These large areas of dust and other particles thrive in an area known as the interstellar medium and are formed when the interstellar medium goes through a gravitational collapse (Universe). It’s during this

1. The earth’s sun is a star, it generates heat and light through nuclear fusion.

1. Why is the phrase “nursery of stars” an appropriate way of describing interstellar matter (nebulae)?

Just like humans, everything in the universe has a purpose. From the beginning of the moment anything is created into existence it grows and fulfills its purpose. Stars are no different. Every day, stars are created by gravity which pulls the star together, the star builds up heat and pressure, and then fusion begins. The process in which a star goes through is known as a star's life cycle. All stars start at the basic nebula phase, change to a protostar, and go on to the main sequence star phase. After the main sequence star phase, there are two different divisions that are determined by the mass of the star. If a star is known as a low-mass star it will have different life changes than a high-mass star. A low-mass star will become a

The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk call the solar nebula. A solar nebula is a gaseous cloud. The nebular hypothesis has become the theory of the origin of our solar system. We can relate this to the vermiculite solar nebula lab. These are related because in the lab it showed us how gravity pulled most of the materials toward the center of the water which the water was representing gravity and the vermiculite that got pulled to the center was modeling the heavier more dense planets. The vermiculite that was pushed away from the center represented lighter less dense

The Pacman Nebula is an H II region or a large gas cloud where a star has recently formed.

The Nebula is the first stage which the star is born. The Nebula is actually a cloud of hydrogen gas and dust in space. There are a couple different types of

Within the constellation of Orion is what appears to the human eye as a hazy star, but is in fact the Orion Nebula, a cosmic cloud composed of dust and brightly glowing gas around 20-30 light years in diameter. This nebula, often called M42 or NGC 1976, is one of the most studied stellar ‘nurseries’ and is located in the Orion constellation, a part of the ‘sword’ hanging from the three-starred ‘belt,’ approximately 1,500 light years away from Earth.

Nebulae are mostly made up of hydrogen gas and dust that has clumped together in space. The gas and dust will start to spin and spiral very slowly at first but eventually speed up. Once a fast

Nuclear fusion is an atomic reaction where atoms combine to form a bigger atom with less mass. The most common nuclear fusion is when hydrogen nuclei forms helium nuclei. This occurs in stars that are small such as our sun. When there is low amount in nuclear fuel a star then turns into a red giant as its core grows smaller, denser, and hotter. Our sun will eventually turn into a red giant, theoretically vaporizing Earth. Once the core has nothing to fuse but iron, it will immediately begin the final phase. The temperature in the core rises over 100 billion degrees and then the star explodes. After a supernova, all that’s left of the star is a small, dense core called a neutron star. Also after the explosion, a black hole

For the star to maintain this balance it must maintain fusion within the core, however with much larger stars, the

The white light that one can see is known to be the origin of our solar system. Milky Way galaxy is a gravitational bound system consisting of stars, stellar remnants, an interstellar medium of gas and dust, and dark matter. It was named after the milk because of its appearance. It happen to look as a dim glowing arching across the night sky that can only be seen by the telescope. The Milky Way is a combination of different aspects that contributes to its incredibility. These include the age, surrounding galaxies, and clusters.

Since we first gazed upon the heavens, man has been perplexed over where the bright lights in the sky have come from. This report will provide information for the birth and death of both low and high mass stars that is supported by scientifically proven statements and observations. It is the long held belief of many, that molecular clouds are the nurseries of stars. These dense clouds of gas are most often found in the spiral arms of galaxies. Obviously, smaller cloud produce low mass stars while large clouds produce high mass stars which collapse much faster than their smaller siblings during the protostar phase ( Washington). At this point, the cloud is cool with very low pressure. Once these clouds of gas become dense enough, they collapse to create the beginnings of a star know

A star is a sparkling bundle of gas bound by gravity into a solitary object and is fueled by atomic combination at the center. There are trillions of stars in our universe and all are distinctive and extraordinary. Their mass, color, shape makes them all distinctive but mass is the only thing that makes them unique. There are numerous phases of stars life including main sequence stars, red giants, white dwarfs, neutron stars, and dark holes. All stars additionally have a lot of varieties in each one phase of life. The life of a star starts in a cloud, an incredible gathering of gas and dust. When enough mass has aggregated into a solitary item, gravity compels the mass to crumple into the middle. Because of weight and rubbing, the center gets so hot that it starts atomic combination and a protostar is made.
