Transcript of Galaxies

Galaxy
A collection of stars, gas, and dust held together by gravity
nebula
a cloud of gas and dust that forms from an exploding star and from which stars can form (think ... beginning and end)
SPIRAL
Barred
Ir
Dense Nucleus
older stars
little gas & dust
black hole
curving arms
rich in gas & dust
young stars
bar through center
thought to be temporary during transition from barred spiral to regular spiral, may result from gravitational tug from the stars within the galaxy or that of a nearby galaxy
scientists have been able to
accurately measure the nucleus of our galaxy along with the movement of the stars in our galaxy. Based on this data, scientists believe the Milky Way Galaxy is a Barred Spiral
No noticeable shape
Random collection
abundant gas & dust
young stars
may form during galaxy interactions
astronomers classify galaxies
by their SHAPE

Galaxies:
Types and
Characteristics

Gravity is a force of attraction that can bring galaxies together
under certain conditions (distance/mass)

interactions between galaxies can cause a change in shape
