Stellar Evolution Did you know that stars don’t stay as stars, they change over the course of time. Stellar Evolution is the star's life cycle. It includes the birth, life, and death of a star. Stars die out due to their mass because their fate depends on it. Stars have two main masses so, each mass results a different ending for each star. The two main masses are Low Mass and High Mass. These two masses of stars have different endings, so let us begin on each of their life cycles.

beautiful to him but he felt so small in the world. He then goes on and talks about how we as humans try to imagine the size of the world we live in. He then starts to talk about Garth Illingworth and how he studied galaxies. He then talks about the distance of the most distant galaxy. He then starts to talk about how long ago people didn’t even know how big the world was. They believed everything was infinite. Lightman then writes about how they finally measured Earth and how they figured it out

A new study proposes the possibility that the minor mass extinction event on Earth about 2.59 million years ago could have been a result from a supernova explosion. It is believed that cosmic rays from a supernova could have potentially altered the climate and led to the minor mass extinction towards the end of the Pliocene epoch and at the beginning of the Pleistocene. Researchers ran computer simulations of supernovas and focused on how the affects could have changed Earth’s climate and biosphere

The above image was posted on April 28, 2016 as NASA’s image of the day. This is a dust angel nebula. A nebula is a cloud of dust and gas that is visible when light reflects off of it. This nebula is about 300 light-years away from our galaxy, and is a collection of cosmic dust clouds. The nebula gets the cloud-like display from light projected from the Milky Way which is then bounced off of the molecular clouds, where the dust releases UV radiation as a red light/orange light (Space, 2013). The

In the article, the author explains how astronomers have discovered a star system that have possibly left behind a white dwarf after a weak supernova explosion. For instance, Type Ia are mini supernovas and are important because they are used to measure the distance and the expansion of the universe. Therefore, the Type Ia demonstrates supernova, they noticed they were viewing the light of the star that lost its outer hydrogen cover, which caused it to reveal its helium core. In addition, astronomers

the force that pulled people together and strife being the forces the pushed people away. Empedocles basically said that before the universe everything was pulled together by love and eventually it exploded with strife releasing all the stars and galaxies. This theory is much like the big bang theory, which states that there was first nothing and then a big bang happened and everything was created. Next Empedocles thinks everything is made up of four elements. These elements being water,

There’s a buzz in this community about an asteroid that will pass in 2028. The public wants to know if it will be any danger. I’m jake Rosenbloom, and this is the SciPod. Today I will be discussing about the Universe’s creation, and the things inside it. There are many theories suggesting how the Universe was created. The most widely accepted theory is the Big Bang Theory. It says, the universe expanded exponentially from “Time 0”. Another theory is “Steady State Theory” which states the density

One day the universe will turn dark forever as the last star fizzles out and that star will most likely be a red dwarf. When a red dwarf star forms it possesses important properties that give it the potential to host rocky planets similar to Earth. Therefore the creation and resulting properties of red dwarfs form stars that can provide energy to planets which may one day be hospitable to life forms. First the process of formation of red dwarfs will be explained. Then, the properties of these

Since the time people have looked in the sky and studied stars, Uranus has been seen and know, but not as a planet, but instead as a star. Uranus was recorded in Hipparchus’ star catalogue (128 BC) as a star, and remained as a star until 1781 when William Herschel found something particular strange about the so called star. Sir Herschel was studying double stars for the purpose of understanding the motion of stars and to find the means of their parallax shifts. When looking at one of the stars

Have you ever seen a supernova in person, if not not it was probably because Supernovas are difficult to see in our own Milky Way galaxy because of dust blocking our view. Supernovas are 33 light years away. A website called eartsky.org stated “there might be one dangerous supernova event in Earth’s vicinity every 15 million years” . Another says, “that, on average, a supernova explosion occurs within 10 parsecs (33 light-years) of the Earth every 240 million years.” Only three Milky Way naked-eye
