3. Why are less massive stars thought to age more slowly than more massive stars, despite the fact they have much less “fuel”?

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

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

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

The Cone Nebula has a resemblance to the Pillars of Creation, which are found in the Eagle Nebula. These pillars are usually quite common in large star-forming regions and have been believed to be incubators for the young developing stars.

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

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.

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

A star has 5 definite stages and 3 stages which can vary between stars. The 5 definite stages are a Nebula, a Star, a Red Giant, a White Dwarf and a Red Dwarf. The stages that can vary are a Supernova, a Neutron Star and a Black hole. As the star goes through each stage, it can change size dramastically. An example of this is a Red Giant, which is 100 time the size of the Sun, compared to a Red dwarf, only 1 tenth the size of the sun (Life cycle). An interesting fact is “The closest star to Earth is Proxima Centauri, located 4.2 light-years away. In other words, it takes light itself more than 4 years to complete the journey from Earth. If you tried to hitch a ride on the fastest spacecraft ever launched from Earth, it would still take you more than 70 000 years to get there from here.” (Interesting facts)

According to website, “The Life Of A Star”, “The star begins to release energy, stopping it from contracting even more and causes it to shine.” Once a star starts to flicker rapidly and become even bigger than the star’s original size, the name will change from a high or low mass star to a supergiant (for high mass) and a red giant (for low mass stars). Red giants and supergiants are the result of a star running out of fuel for nuclear fusion to occur. Helium begins to build up in a star's center causing slower paces for new atoms to form, such as carbon, oxygen, and even iron. The book, “The Life And Death Of Stars” states, “But in the case of other stars, as the hydrogen fuel runs out, the star contracts and squeezes its helium. The central temperature rises until the helium atoms begin to form more complicated atoms - carbon, oxygen, and even heavier elements like iron. This information proves that stars start to form these atoms in the red giant/supergiant stage. The outer layers of these stars start to cool and become red. Red giants and supergiants are the stars that start the stage of a star dying

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

Low mass stars are exactly what you think. They are the creation of smaller molecular gas clouds and the subsequent protostars. Our very own Sun comes from this family and has relatively low luminosity and temperature. Thankfully, the smaller a star is the less fuel it needs to consume. This means that it will also have a longer lifetime before exhausting it energy supply in the core. But, once it has eaten though all of its gas the star will grow redder, larger, and more luminous (NASA).If we continue to track the life of a star like our Sun, we can see that next

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

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.

The changes that occur during a star 's life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine, they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars, shine until they exhaust their fuel, and then die a predictable death based upon their initial mass.
