Galaxies and The Big Bang

Galaxies and The Big Bang. What are galaxies? How do they relate to the Big Bang Theory?. Galaxies formed from the gas, dust, and matter propelled into space after the big bang that began the universe nearly 14 billion years ago. They are only a few million years younger than the universe.

  1. Galaxies and The Big Bang

  2. What are galaxies? How do they relate to the Big Bang Theory? • Galaxies formed from the gas, dust, and matter propelled into space after the big bang that began the universe nearly 14 billion years ago. • They are only a few million years younger than the universe. • Big Bang Theory is the theory (that has been proven) that all matter in the universe was created from a huge explosion called the Big Bang & the universe has continued to expand outward ever since (and will continue to do so until the end of time.)

  3. Four Types of Galaxies • Spiral • Elliptical • Irregular • Lenticular

  4. Comparison of Galaxies http://www.glyphweb.com/esky/default.htm?http://www.glyphweb.com/esky/concepts/galaxies.html

  5. Spiral Galaxies: look like hurricanes http://www.glyphweb.com/esky/default.htm?http://www.glyphweb.com/esky/concepts/galaxies.html

  6. This image of the large spiral galaxy NGC 1232 was obtained with the Very Large Telescope (VLT). Its distance from Earth is about 100 million light-years. It contains more dark matter than visible matter. Credits: Spaceweek International http://www.esa.int/esaKIDSen/SEM346WJD1E_OurUniverse_0.html

  8. These shape-shifting galaxies have taken on the form of a giant mask. The icy blue eyes are actually the cores of two merging galaxies, called NGC 2207 and IC 2163, and the mask is their spiral arms. The false-color image consists of infrared data from NASA's Spitzer Space Telescope (red) and visible data from NASA's Hubble Space Telescope (blue/green). NGC 2207 and IC 2163 met and began a sort of gravitational tango about 40 million years ago. The two galaxies are tugging at each other, stimulating new stars to form. Eventually, this cosmic ball will come to an end, when the galaxies meld into one. The dancing duo is located 140 million light-years away in the Canis Major constellation.
