Pre-main sequence star

How Stars Came to be and Their History The radiance of the stars is masked in secrecy. Only those who wish to ponder the vastness of the stars can be enlightened to their true beauty; their ability to create something from nothing is astounding. People revel at the beauty of the stars, generally enjoying a night under the twilight sky. The stars hold so many mysteries that are seldom ever questioned, but how many people ever wonder where the stars come from? How long a star’s lifespan is or why they fall from orbit? Why do the stars appear different colors when seen through a specialized telescope? Curious about the mythology of stars and why people use them for guidance? Throughout history people have used the stars to navigate their way around.…

and the sky and… the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it plays an important role in the universe. The street light flickers on above your head, snapping you out of your reverie and reminding you that you still have an essay to write. You sigh, sit up, and walk to your house, the…

the more short lived and less dense colonies of young stars that group up to create open clusters, globular clusters exist as far greater, spherical collections of aged stars that contain many low mass stars, sometimes numbering among the thousands. Globular clusters are more commonly found among a galaxy’s centre where the vast majority of stars are. It is thought that globular clusters arise from large gas clouds early in the creation of our universe and they assist the formation of greater…

gathered data of a star’s spectral type and there temperature. They plotted these data on graphs and discovered that many patterns emerged linking the mass of a star to its lifespan. From the noted trends and correlations they formed what is now known as the Hertzsprung Russell Diagram or commonly referred to as the HR Diagram. The HR Diagram is used as an important tool in the study of astrophysics. Specifically it is a graphical tool that Hertzsprung and Russell formed for astronomers to use…

fine girl/guy kiss me,” or maybe not. Learning this phrase has helped multiple astronomers to educate themselves on the spectral classification of stars and continues to do so in today’s time. Annie Jump Cannon’s legacy will carry on lasting a lifetime! The first letters of each word in the phrase represents the seven main types of stars. Starting with ”‘O,” these stars are very young, blue, hot, massive and extremely bright star. This type of star is very uncommon similar to the “B” and “A”…

Stage Four: Protostar By this stage of the stars evolution, 100,000 years after the process began, it can now be plotted on the Hertzsprung-Russell diagram, which is used to compare the many different stars. Although it is still not fully formed, we are able to determine the type of star it will become based on its luminosity and temperature. In the nucleus of the condensed cloud, which could now fit within the orbit of Mercury at less than 58,000,000 km wide, electrons and protons are ripped…

The Vega has many properties and characteristics in the star. The Vega star is 25 light years away from the earth and the mass is 2.1 times bigger than the sun. It is about 455 million years old and each rotation period is 12.5 hours. The diameter is about 2.2 million miles, which is 2.5 times the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main…

An astronomical star catalogue lists stars by number according to different criteria (such as their magnitude), which can provide insight into the positions of stars, how they change over time, and even the history and culture of the astronomers who create these catalogues. As early as the 2nd millennium B.C.E, star catalogues have been kept (Van der Waerden); they can be seen all over the world and across cultures, increasing in breadth over time as the technology of telescopes advanced and…

Star Formations Every star you see at night in the sky is bigger and brighter than our sun. Stars are born within clouds of dust and gas that is spread throughout most every galaxy. The life of a star includes many stages from nebulas to the mysterious black holes. Stars are responsible for the creation and circulation of heavy elements such as carbon, nitrogen, and oxygen. The elements characteristics are informally bound to the characteristics of the planetary systems that may consolidate…

The video we watched in lab, “Life and Death of a Star,” gave us incredible information regarding the life cycle of a star. There are billions of stars out there and in our galaxy, we have about four billion. Stars, which are ignited by the power of the atom, burning with light, heat and wrath, stars are anything but peaceful. They collide, devour each other, and explode in enormous supernovas. These “supernovas” are known to be the largest explosion in the universe. Throughout the video, we…
