Energy Star

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…

Stars are complex and giant balls of matter that have many things to understand about. Stars are born of gas and dust and have a life cycle based on their original mass. All stars start out in their main sequence, but the first difference between the mass of stars is when they stop producing energy. The low-mass stars become giant, and the high-mass stars become super giant. For low-mass, the star then becomes a planetary nebula, then finally a white dwarf. High-mass stars become a supernova, a…

little glowing dots are scattered across the night sky. They are known as stars. There are several billion stars in our galaxy, but only a few are seen with the naked eye. Stars are by definition, large exploding balls of gas made up of mostly hydrogen and helium. The two most unstable elements on the periodic table. The largest star in our galaxy is the sun. It’s the largest star and one of the few stars that are going through a star wide nuclear reaction. The reason the sun has yet to fully…

the formation of planets based on our current scientific understanding. a) Star and planet formation starts inside a collapsing cloud of gas and dust inside a bigger cloud called a nebula. Because of gravity pulling materials in the collapsing cloud closer together, the center of the cloud gets increasingly more compressed and because of this get hotter. The dense hot core of this collapsing cloud becomes the kernel of a new star. b) Next motions inside the cloud cause it to start churning. As…

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 about one million times denser than that of the sun. A single sugar cubed amount of white dwarf would weigh approximately one tonne. Its volume comparable to that of the earth, and it’s mass comparable that of the sun. A white dwarf has a faint luminosity which comes from the emission of stored thermal energy. The nearest known white dwarf star is…

Supernova can occur in one of two ways, either near the end of the star life or in a binary star system. Inside of a binary star system one of the stars would need to be a white dwarf which is a star who has depleted most of its energy and begins to take away energy from the other star in the system ("What Is a Supernova?"). If it were too depleted too much energy from the other star it would begin to go supernova due to raising its core temperature, igniting carbon fusion…

the time you got anywhere near it your atoms would have been ground up and used to fuel the black hole. It is this fear of the unknown that is the scariest thing about a black hole. How could we mitigate the effects of a force of nature that eats stars? Further explanation Black holes are suns that have collapsed in on them selves because they have gained to much…

Ever wanted to know more about nebulae or galaxies? A nebula is a cloud of interstellar dust, stars, and gas (usually hydrogen and helium). A nebula is less dense than a vacuum and mass less than a few kilograms although it is usually the size of the earth or bigger. A galaxy is gravitationally pulled system of stars, stellar remnants, interstellar gas, dust and dark matter. Galaxies range in size in lightyears. Galaxies, they are what holds our solar system and many, many more. We may not be…

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. When the star explodes it…

to two main factors. Fewer stars (the universe's light bulbs) are being made and our universe is expanding. “More stars are dying then being born” we know this because after looking 2 billion years into the past we have seen a brighter universe, this has many implications. Since stars are responsible for almost all the light and energy in our universe a declining of them means a declining of their produce which will darken and freeze the universe. The absence of stars is a…
