Binary 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…

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…

I choose the phoenix because first it sounds cool and it is easy to draw. It is located on the southern sky, based on the photo it looks like it has 6 stars. The phoenix is the 37th constellation in size. The constellation was named after the mythical bird that rises from its own ashes.The mythical bird phoenix is known as the sacred fire bird across many mythologies: Greek, Persian, Arabic, Egyptian, Roman, Turkish, Indian and Chinese among others. The phoenix was said to have resembled an…

they all formed from a disc of remains around the proto-Sun. Another one of the pieces of evidence we have is that all of the planets have the correct characteristics that convey that they formed from a disc of chiefly hydrogen around a young and hot star. Lastly, in the model of the Nebular Hypothesis, the Sun is formed out of hydrogen. This can be proved, surveillance of the Sun shows that the Sun acts as though this theory is true. The formation of the Sun can also be proved through…

I have always been fascinated with the night sky and have enjoyed looking up at it without the light pollution. While living in Las Vegas I would have to commute at least an hour past Red Rock or Valley of Fire to escape the bright lights of the city. Since moving to a small town I have been able to enjoy watching the moons and her phases, meteor showers, and seeing where the constellations are in the night sky. William Herschel was a German composer, teacher, and musician residing and…

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 influence high mass stars have on our Universe is that they create and affect many other bodies in space. For example, when they explode, they create supernovas and eventually those supernovas create black holes. They also are very beautiful and powerful. A high mass star starts out in a nebula and is created by the matter that lies in the nebula. When the hydrogen gas is forced together due to gravity, the star begins to spin and reach extreme temperatures. It gets so hot that it begins…

Nothing, not even light is able to escape a black hole because of its strong gravitational pull. Black holes are the last great stage in enormous stars lifetimes that had been as big as ten to fifteen Suns. With zero force of gravity the black hole sucks up light from such a star. The light from the star then gets stuck in an orbit. Which that dark star then turns into a black hole. Matter and energy are pulled from the black…

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…
