Brain. Pop Video V: 0 Galaxies until minute 2: 00 As you watch, write definitions in the table for the different types of galaxies.

Types of Galaxies: Spirals Spiral galaxies are so-named because of the graceful shapes of arms emanating from a bright central nucleus.

(Hubble Space Telescope Image)

Types of Galaxies: Ellipticals Elliptical galaxies lack spiral arms and dust and contain stars that are generally identified as being old.

Types of Galaxies: Irregulars Irregular galaxies lack any specific form and contain stars, gas and dust generally associated with youth (They are “new” galaxies.

Balloon Universe V: 0 Conclusion Statements: 1. The dots on the balloon represent different galaxies. 2. All of the galaxies are moving away from each other. 3. We know galaxies are moving away from each other because the wavelengths emitted are longer , shifting them towards the red end of the spectrum. This is called red shift. 4. Scientist think that 14 billion years ago there was an explosion called big bang. 5. The force from this explosion is why all the galaxies are moving away from each other.
