BIG BANG THEORY

10 billion to 20 billion

Galaxies formation Coalesce, collapse,

compress Building blocks of

galaxies

Grew in size and shape Expanding High speed Except galaxy clusters Dance around

Antennae galaxy undergoing a collision that will result in their merger

A starburst galaxy that has 10 times the star formation than a normal galaxy

Types Of Galaxies

Spiral Galaxies

Elliptical Galaxies

Irregular Galaxies

SPIRAL GALAXIES

PARTS:° Flat disks

° Bulging center ° Spiral arms

GALAXY’S DISK ° stars
