Galaxies and Shapes (…Cont.)

Spiral galaxies: can be broken down in two categories

Circular spiral - round center

Barred Spiral – bar center

Elliptical galaxies: are shaped like an egg.

Galaxies!It is estimated that there are billions of other galaxies in the

universe.

The Milky Way (the name of our GALAXY…and a delicious candy bar )

is the band of light that is produced by the thousands of stars that lie in the main section of our Galaxy.

We are a spiral galaxy.

Star Attractions: Constellations

What do you see when you look up into the sky?

Humans have seen group of stars that looks like

imaginary animals, people, or mythological

Ancient stargazers gave names to these groupings,

as constellations.

Asteroids

Asteroids are chunks of rocks that never became planets

COMETS

A comet is a celestial body made of dust, gases, and ices (mainly water and carbon dioxide) that moves in an extremely elongated orbit about the sun.
