History of Scorpius
In mythology, Scorpius was
the name of the scorpion that
the goddess sent to kill Orion
by stinging him on the heel.
This is the reason that Orion
and Scorpius are separated
from each other and are on
opposite sides of the sky.
Life Cycle of Antares
Antares is currently a Supergiant
star, which means it is in the
middle of its life cycle. The larger
the star, the shorter its life will be.
This means Antares will not live
very long in star years. It started
out from a large cloud of gas and
dust called a nebula. Antares was
born when the gas and dust
became so dense and hot that
nuclear fusion began and formed
a protostar. It then changed into a
massive star. Antares proceeded
to its current stage as a
supergiant. As it continues its
death cycle, its next step will be to
become a supernova and explode.
The bottom cycle is Antares’s.
