quite large which indicates the amount of matter it has. As you know‚ Earth’s galaxy is called the Milky Way. Many “stellar” black holes are located in our galaxy. This is a certain kind of black hole which has the mass up to twenty times more than the sun. Our largest black holes are called “super massive.” These black holes are more than one million suns together. They’re located at the center of every large galaxy. These holes are called “Sagittarius‚” and have a mass of about four million suns

Introduction Ask people to introduce themselves‚ and they will likely give their first and last names. Ask for more information‚ and they may refer back to their parents or grandparents. Additional inquiry may prod them to talk about a few of their ancestors. How many times can someone expect to hear people refer to their connection to early man or to the universe – the cosmic connections that enable people to co-exist with other humans and things – living and non-living? Is this apparent

universe is “why don’t the galaxies fly apart when the stars circle around it?” Due to the fact that scientists were unable to explain this‚ they thought that a mysterious force must be holding the galaxies together. That mysterious force is called the Dark Matter. The third thing that fascinates scientists’ minds is how did the galaxies form? The first theory states that the galaxies collapse as single objects out of gas clouds. More and more gas falls in the galaxy because of the gravity and it

last as long as five months; spanning from December to April. From what I said before the stars are endless. They stretch far beyond anything I could ever imagine. The universe is vast and contains hundreds of billions of stars and galaxies. In our Milky Way galaxy alone we have billions of stars and we are still learning

Phoenix The Science of Stars Paper The stars are the majority and most widely acknowledged astronomical components that symbolize the most essential development of the galaxies. The disbursement‚ age‚ and the framework of the night sky in the galaxy maintain a record of the heritage‚ evolution and characteristics of our galaxy. More important the stars are integral to the fabrication and allocation of heavy elements. Notably corresponding to oxygen‚ carbon‚ and nitrogen‚ is intimately associated

| 1.Intro The word “Universe” and its meaning alone ‚ represents an unimaginably enormous space ‚ which includes everything that’s surrounding us: the galaxies ; the uncountable shining stars ; the panoramic‚ yet toxic clouds filled with elements we use or live with every day ; the sneaky black holes which crawl around the corner and drag everything within itself ‚ including light; the supernova ‚ the planets

-Our sun is one of a hundred billion stars in our galaxy. Our galaxy is one of bilions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity. Werner von Braun quoted these amazing words in the San Diego Union-Tribune in 2005.

Q1. Outline the historical development of the models of the universe from the time of Aristotle to the time of Newton. Aristotle: Geocentric model of the universe involved a series of 56 concentric spheres to which celestial objects were attached. The Earth was not in motion as the stars showed no measureable parallax. Each planet‚ the Sun‚ and the Moon were in their own sphere and the stars were positioned on a larger sphere surrounding all the others. Ptolemy: Geocentric model of the universe

but at a much slower rate. In the twentieth century many scientific developments were made by scientists that contributed to the creation of the Big Bang Theory. In 1910 Vesto Slipher was the first person to observe shifts in spectral lines in galaxies. What he had discovered was the galactic redshifts. A galactic redshift is a displacement of spectral lines toward longer wavelengths. What Slipher specifically observed was that the spectral lines of many nebulas exhibited a red shift that indicated

Use a marker to make small‚ filled-in circles on the balloon. The circles represent galaxies. 2. Pick four of the circles around the balloon and label these A‚ B‚ C‚ and D. 3. Hypothesize what will happen to the distances between the labeled circles when you blow up the balloon ¼ full‚ ½ full‚ and ¾ full. 4. Measure the starting distances‚ in inches or centimeters‚ between each of the labeled galaxies. Record the measurements in a data chart. 5. Blow up the balloon about ¼ of the
