  • Slide #2 says the Sun is the main star of the Milky Way, which may need revision. Our sun is considered a main sequence star on the HR diagram, meaning it is still burning hydrogen before it changes into a red giant. As far as thee main star, there isn't necessarily one. But other than that great presentation.

Transcript of "Differences between galaxies "

  1. 1. Differences Between Galaxies By: Lauren Geisel
  2. 2. Fun Fact : <ul><li>About 25% of the universe consists of “dark matter” and about 70% of the universe consists of “dark energy”, which only leaves about 5% of the universe that is visible to us . </li></ul>
  3. 3. What are Galaxies? <ul><li>Consists of billions of stars </li></ul><ul><li>Example: Our sun is the main star of the Milky Way. </li></ul><ul><li>Interstellar medium (streams of protons moving from the stars) of gas and dust to form stars </li></ul><ul><li>Example: The sun was created by an interstellar medium </li></ul>
  4. 4. True fact : <ul><li>Each Gala xy has 100 to 200 billion stars en circling its cente r ……. That is about how many stars that make up the sun </li></ul>
  5. 5. Types of Galaxies….. <ul><li>Spiral Galaxies </li></ul><ul><li>- Made up of gas dust and new stars </li></ul><ul><li>The Milky Way </li></ul><ul><li>- Leading astronomers to think that we live in a spiral galaxy. </li></ul><ul><li>Elliptical Galaxies </li></ul><ul><li>- Highly flat in size and in size it ranges from millions to trillions of stars in its galaxy. </li></ul><ul><li>Irregular Galaxies </li></ul><ul><li>Very uncommon </li></ul><ul><li>Once was either a spiral galaxy or a elliptical galaxy </li></ul>
  6. 6. True Fact: <ul><li>The average speed of a galaxy goes about 140 miles a second </li></ul>
  7. 7. Differences between the galaxies <ul><li>DIFFERENES BETWEEN: the Milky Way and elliptical galaxies </li></ul><ul><li>The Milky Way should refer exclusively to the band of light that the galaxy that makes the night sky. </li></ul><ul><li>It also includes between 200 billion and 400 billion stars. The diameter of the galaxy is 100,000 light years. The milky way is also known as a spiral galaxy. It is also in a local group which contains 3 large galaxies and 30 small galaxies, which includes the milky way. </li></ul><ul><li>The elliptical galaxy is a galaxy has an ellipsoidal shape to it. The galaxy’s have close to 10 trillion solar masses that form into stars. </li></ul>
  8. 8. True Fact: <ul><li>A galaxy that is known as a “Small Galaxy” has less than a billion stars, but the other galaxies known as “Larger Galaxies” have more than a trillion stars </li></ul>
