Bright Star

barely visible in the sky. Some Nebulas can be seen with a naked eye, this one can not because it does not glow as bright as others. This star isn’t as bright as others because it is larger. Red Supergiant : The Red Supergiant is a star with a supergiant luminosity class. The “red” part of Red Supergiant is because of the cool temperature,…

look up to the sky and see millions of stars, and I wonder to myself. What makes them light up so bright, and what makes them a star? What does it take to create a star; they just don’t pop out and shine bright. I want to know the process, and how long it takes for a star to be born. I am also curious to know if the star can die. I plan on finding the answer. I believe that they are created by gases and that they die when they use up all of their gases. Stars have had an impact in our society…

They could be confused with supernovae, but they surround a star. Supernovae are bright when they first are formed and normally spread a hundred light-years across (Arnett). The explosion could be seen in the sky but it would more like a star because of distance between the earth and the nova. Dark nebulas block light from surrounding stars and join with reflective and emission nebulas(Arnett). Reflective are normally blue in color but are not as big…

12 main constellations that make up the winter constellations. Each having its own main stars or star clusters. These 12 constellations make up our winter night sky. They are Cancer (the Crab), Canis Major (the Big Dog), Canis Minor (the Little Dog), Crater…

shows many patterns and properties of stars based on plotting them by their temperature on the surface and their light they emit, or luminosity. Created in 1912, the HR diagram was made by two astronomers, Ejnar Hertzsprung and Henry Russell who found patterns with stars’ properties. The Hertzsprung-Russell Diagram shows how every star goes through different evolutionary stages. These evolutionary stages are based on the internal structure of the star and how the star produces energy. On the…

nebula looks like a donut-like ring wrapped around the middle of a football shaped cloud of glowing gas. It’s about one light year across and the glowing light the Ring Nebula produces is not coming from the planets but rather from the hot central star ionizes atoms in the gas forming intense ultraviolent light. As seen through the telescope, the reddish color of the outer ring is coming from the nitrogen and sulfur, the cyan color of the inner rings is coming from the glow of the hydrogen, and…

Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on June 6, 2006 the Galaxy Evaluation Explorer, from NASA, found that there were a large number of new stars on the outer rim of the galaxy, which was believed to be lacking in the material needed to make a star. The Galaxy Evaluation Explorer also found…

even though it is about 2.5 million light-years away from Earth. The unaided eye, however, can only perceive the galaxy as a whole and is unable to distinguish features within the galaxy. Luckily, microscopes combined with the intellect of many bright astronomers over the years have allowed us to better understand what the human eye cannot see, in particular what lies beyond the Milky Way Galaxy in our neighboring galaxy. This paper will focus on some of the recent discoveries and…

SUPERGIANT STAR Supergiants are among the most luminous and massive stars, ranging between 7-10 solar masses and can range in brightness from thirty thousand to hundreds of thousands the output of our sun. They reside in the top region of the Hertzsprung-Russel diagram; having temperatures from 3,500k to over 20,000k and having bolometric absolute magnitudes between -5 and-12. Supergiants are massive enough to begin burning helium gently in their core before it becomes degenerate, and without…

Hertzsprung-Russel Diagram, or the temperature of stars relative to its luminosity, the theoretical H-R diagram. Stars have specific evolutionary stages based on their initial mass, dictating its internal structure and means of energy production. The phases in stellar evolution correspond to alterations in luminosity and temperature. There are three main regions present on the diagram, the most dominant is the main sequence which is where approximately 90% of all known stars lie and extends from…
