    Pillars Of Creation

    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 were given so much information about stars and with the help of some cutting-edge computer graphics, astronomers are now able to see so much more now compared to many years ago. Pillars of Creation was brought up, a photograph taken by the Hubble Space Telescope of the elephant trunks of interstellar gas and dust in the Eagle Nebula. This is about 6,500-7,000 light years away from Earth. Eagle Nebula is known to be a young open cluster in the constellation of Serpens. Pillars of Creation is basically gas and dust in process of creating new stars, while also eroding the light from nearby stars that have been recently formed. One may ask, “What is the key component of stars?” and the answer this question is Hydrogen. Stars are the most basic unit. The formation of a star is when, dense regions…

    The Life Cycle of Stars The life cycle of a star is an incredible, miraculous phenomenon that begins with just two elements: helium and hydrogen. The result is the all well known star that is seen twinkling in the night sky and also what lights up the day here on Earth. There are hundreds upon thousands of stars that take on many different sizes and colors. Depending on the size of the star from its birth, the star could take two paths at the end of its life: turn into a nebula leaving behind a…

    When a star is born it can take one of two paths. It can either take the path of a high mass star or the path of a low mass star. A high mass star will be between 10-50 solar mass and a low mass star will be between .8-10 solar masses. One solar mass is equal to M⊙ = (1.989±0.004) x 1030 kg, which is A LOT. Either path it takes, the one of a high mass or low mass star it will live about 90% of it’s lifetime in its main sequence. Once achieving nuclear fusion the star slowly contracts over…

    mass-luminosity relation. The upper right corner of the H-R diagram is occupied by red giants and supergiant stars, which have low surface temperatures and high luminosities. Red giants have masses which are approximately as low as 0.3 to 8 solar masses, a surface temperature of under 6,500 Kelvin and a luminosity on average 14, 000 times greater than the sun’s. Stars from the main sequence enter this evolutionary stellar stage once the solar core has exhausted its supply of hydrogen, hence…

    These include red dwarfs and yellow dwarfs. Red dwarfs are the most common star in the Milky Way Galaxy that is small and cool. Yellow dwarfs are also known as G-Type main sequence stars; they are also small. Giants and supergiants are old, large stars. Red giants are usually orange and are about six hundred light years away from Earth. Blue Giants are hot, blue stars that burn helium. Supergiants are the largest type of known star, and are sometimes as big as our entire solar system. When they…

    Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

    Pulsars: Lighthouses of the universe Imagine a star between four and eight times the mass of our sun exploding into a supernova. Next imagine watching the inner core condense into a sphere due to the enormous gravity of the star like there’s a new star forming in its place. This new star is so dense it smashes electrons and protons together forming neutrons which form a neutron star. This is the recipe for a pulsar. There are several types of neutron stars but this essay will highlight pulsars.…

    Did you ever think on how the universe ever started ? It all started in total darkness. An astronomer named Edwin Hubble found out that the galaxies were moving farther away, he knew that by a telescope that he created and it is called the hubble telescope. When the universe exploded it began to spread really quickly and when it exploded the universe had a very high temperature when this happened. Which created formation of elements ,gravity,redshift ,doppler effect,CMB, many more . The big…

    Orion Nebula.The turbulence in the depths of these clouds produces enough mass of knots.Because its own gravitational attraction,and the gas and dust can begin to collapse. Then the material at the center begin to heat up which is known as protostar . The heart of the collapsing cloud will one day become a star. Since stars are formed from hydrogen, will they deform? If yes, when/how will star deform? The starting point of all the stars, including our sun, begins to shrink and start from…

    They arise from the core collapse of massive stars which reside in regions of space experiencing new and active star formation (Savaglio, 2013) and as they are intensely luminous and high in both gamma-ray emission and multi-wavelength afterglow their rate is relative to the star formation rate (Gehrels & Meszaros 2012). However, the core collapse from a supernova explosion from the death of a star that results in the formation of a neutron star is not powerful to create or explain LGRBs.…
