Mesoamerican Astronomy - ... The Maya interest in the planet Mars established by the Dresden Codex, has revealed a number of cycles unknown to Western astronomy. Anonymous but ingenious Maya astronomers recorded two empiric sidereal intervals of Mars, a long one (702 days) that included a retrograde loop and a short one that did not. (Authentic Maya) The study of these cycles illustrates the level of practice of naked eye sky watching and the role of such activity in Maya culture. Pleiades: The sacred calendar of the Maya is based on the cycles of the Pleiades....   [tags: Astronomy]

Black Holes and My Love for Astronomy - When I was growing up there were things in life that always seemed to fascinate me. Most of them were usually science based. Things like elements on the periodic table, where did the stars come from and what lies at the end of the universe. I think the one question that always had my attention was what is a black hole. I can remember asking my parents when I was at about the age of eight or nine what a black hole was, and what was its purpose.

When considering super earths, one must remember that mass is not the only geographic asset of a life-sustaining planet, as a planet made of gas could not support life; solid formations would not have solid ground to stabilize upon (Spotts). A “Goldilocks zone” is the habitable zone surrounding a star, described as the area around a star that is not too hot and not too cold to sustain life. More specifically, water on a planet in this zone would not be consistently boiling or freezing (Kaufman)....   [tags: Astronomy]

Elliptical galaxies also consist of older, more evolved stars. “Spiral galaxies consist of a rotating disk of stars and interstellar medium, along with a central bulge of generally older stars” (Wikipedia, The Free Encyclopedia). Stars, gas, and dust whirling around the central nucleus form bright spiral arms that extend outward from the bulge.

Scientists Who Unlocked the Mysteries of the Universe - Scientists Who Unlocked the Mysteries of the Universe      Since the dawn of time, man has yearned to know the origin of existence, how life was started, and the source of creation. Many scientists, from ancient Greece to modern civilization, began the search for answers by first studying our solar system, mapping the stars, trying to unlock their secrets. These eight scientists paved the way for any basic knowledge of the universe.      Born in 270 BC, the Greek astronomer Aristarchus of Samos, was the first scientist known to suggest that the earth revolves around the sun....   [tags: Astronomy Research Papers]

Today, Mikulski could host a Capitol Hill star party: The orbiting telescope has generated more than 100,000 photos of celestial objects, including a cemetery of dying stars, elephant trunks of dust and hydrogen gas twisting in the Eagle Nebula, jovian storms and aurorae, the rocky rings of Saturn and the colossal supernova smoke rings blown from an exploded star, to list a few....   [tags: Shuttle Astronomy Space Essays] 3667 words

How a Star is Born - Cosmic Nurseries - Mommy, Where do Stars Come From. Since my entire thesis for this paper is about how a star is born, I guess the first thing I should start out with is by telling you exactly what a star is. Stars are self-luminous gaseous spheres. They shine by generating their own energy and radiating it off into space. The stars' fuel for energy generation is the stuff they are made of --hydrogen, helium, carbon, etc. -- which they burn by converting these elements into heavier elements. Nuclear fusion occurs, which is when the nuclei of atoms fuse into nuclei of heavier atoms....   [tags: Astronomy] 1167 words

It is a star among hundreds of billions of stars within our Milky Way Galaxy, and our galaxy is one of billions of galaxies in the universe. Stars live for a very long time; millions, billions, or tens of billions of years so we can never really observe the life of a star; its birth, life, and death. In determining the life cycle of a star, astronomers observe many of the billions of stars around us and see them at different stages of life, therefore piecing together a star's evolution....   [tags: Astronomy] 748 words

If you were to live on the Moon, you would feel like you only weigh 26 pounds. That is because the Moon's gravity is only 17% of Earth's gravity.

Star Formation - The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However, the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system's gravity, so star formation only occurs in a few areas. The sites of star formation in the galaxy are mostly located within molecular clouds – expansive, cool clouds of mostly hydrogen and helium gas....   [tags: Astronomy] 690 words

Black Holes - Black Holes The American scientist John Wheeler coined the phrase “black hole” in 1969 to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die. Gravity causes the center to contract to higher and higher temperatures, while the outer regions swell up, and the star becomes a red giant. The star then evolves into a white dwarf, where most of its matter is compressed into a sphere roughly the size of Earth....   [tags: Astronomy Research Papers]

White Dwarfs - White Dwarfs A hydrogen-burning star (like the sun) is kept in equilibrium by a balance between radiation pressure and gravitational attraction. When the hydrogen burns out, the star goes through a number of changes during which it sheds about half its mass. If the mass of the star is less than a critical value, called the Chandresekhar limit, after its discoverer, then this contraction to a smaller size is halted by a quantum mechanical effect called degeneracy. If the mass is greater than this the pressure developed by the electronic degeneracy is insufficient to prevent gravitational collapse to a neutron star or even a black hole....   [tags: Research Science Astronomy Essays]

As the interior of the white dwarf changes and oscillates, the light signal from the star will pulsate at numerous frequencies. By determining the frequencies at which the star pulsates and using these as boundary conditions in stellar models, astronomers can determine the interior properties of white dwarfs.

They usually follow very strict paths around the sun. Comets become most visible when they cross the sun. This also applies to people who view comets with telescopes.
