LIFE CYCLE OF A STAR Stars are formed in nebulae‚ interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries‚ dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released

While both John Keats’s “Bright Star” and Robert Frost’s “Choose Something Like a Star” deal with the steadfastness of stars‚ they differ in that Keats relates it to a romantic couple while Frost relates it to a man struggling for guidance. “Bright Star” relates the qualities of a star‚ for better or worse‚ to a man longing to stay in his lover’s company. “Choose Something Like a Star” The tone that each poet uses to help describe the narrator’s view of the stars is quite similar. Keats is skeptical

The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

John Masefield’s poem "Sea Fever" is a work of art that brings beauty to the English language through its use of rhythm‚ imagery and many complex figures of speech. The meter in "Sea Fever" follows the movement of the tall ship in rough water through its use of iambs and hard hitting spondees. Although written primarily in iambic meter‚ the meter in "Sea Fever" varies throughout the poem. The imagery in "Sea Fever" suggests an adventurous ocean that appeals to all five senses. Along with an adventurous

Poseidon: God of the Sea The Olympian God Poseidon‚ or Neptune in Roman culture‚ is known by mortals as the King of the Seas and the Earth-Shaker. He controls the oceans and the land man walks upon. With the wave of one hand he could create massive earthquakes‚ horrific tsunamis‚ and storms that would destroy entire cities. When he rode across the seas in his chariot the seas calmed before him. As the second most powerful God of Olympus‚ Poseidon was held in high regard by gods and mortals alike

What is Sea-floor spreading? Seafloor spreading is a process of plate tectonics in which new oceanic crust is created as large lumps of the Earth ’s crust split apart from each other and magma shafts up to fill the gap. Who discovered sea-floor spreading? The man who discovered sea floor spreading was Harry Hess. Harry Hess was a geologist. Part of his mission had been to study the deepest parts of the ocean floor. In 1946 he had discovered that hundreds of flat-topped mountains‚ perhaps sunken
