Supernova

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.…

massive. There are rumors that this black hole is in the Milky Way but there is nothing to prove it. Astronomers have said they have taken some pictures soon to be seen. Black holes form when a star collapses. When the star falls this creates a supernova, which is also known as a bursting star. It blasts the star into outer…

On September 6, the sun let its presence be felt by unleashing two massive solar flares. The first eruption, classified as an X2.2 flare, the strongest since 2008, occurred at 5:10 a.m. ET. Shortly after, at 8:02 a.m ET, the star spewed out a bigger, and more dramatic, X9.3 flare — the strongest on record since December 2006. Solar flares, or storms, beginning with an explosion usually above a sunspot, the area where strong magnetic fields poke through the sun's surface. When these spots become…

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 die, they supernova and turn into a black…

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.…

WHITE DWARF White dwarves (also known as degenerate dwarfs), are stellar remnants mainly composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being…

How do stars form? The stars were born among the dust and scattered throughout the most galaxies. There is an example of dust cloud which is the 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…

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. Instead, a LGRB can only be explained as arising when an ultra-energetic supernova becomes a hypernova and creates a black hole that consumes matter so immediately that it releases a substantial amount of energy of the…

I 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…

HR Diagrams The Hertzsprung-Russell Diagram, otherwise known as HR diagram, is a graph that 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…
