Imagine that with new technology you can build a
time machine that travels at light speed (186,000
miles/second).
The unit used to express stellar distance is the lightyear, which is the distance that light travels in a year
(5.8 trillion miles).

Galaxies
V: 0
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

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.
