This is the death of a star
(supernova) viewed by
Tycho 400 years ago it was

with the naked eye

The Life Cycle of Stars
Nebula
Main Sequence Star
Red Giant
White Dwarf
Supernova
Neutron Star
Black Hole
All stars begin as a
ball of gas
& Dust in space
Nebula
The stage of our
SUN
Venus and the International Space
Station crossing the sun.
Has a Temp. Near 5,000
Nuclear fusion occurs at
the core converting
Hydrogen to Helium.
A star’s longest stage.
-6,000 C
Main Sequence Star
The stars
expands to 10 –
100 times its
original size
The star has used
all of its hydrogen
fuel. The center
shrinks.
Red Giant
Has a Temp. Near
10,000 C
Left over centers
of old stars
remain at this
stage.
These are small
hot stars near
the end of their
life.
White Dwarf
This is the death
of a large star by
explosion
Generates a HUGE amount
of light,
brighter than a whole
Galaxy,
and may be seen with
naked eye.
Supernova
The materials
are squeezed
together so
hard by gravity
electrons and
protons become
neutrons.
Neutron Star
Left over from a
supernova and very
massive
So massive light can
not escape. The mass
of 3 suns and about 6
miles across
Black Hole
