2. Red Giant – a
large, reddish star
late in its life cycle
that fuses helium
into carbon or
oxygen.
3. Supergiant –
an extremely
large star
that creates
elements as
heavy as
iron.
4. Supernova –
a powerful
explosion
that occurs
when a
massive star
dies.
5. White Dwarf
– A small, very
dense star
that remains
after fusion in
a red giant
stops.
6. Neutron Star
– a dead star
with the
density of
atomic nuclei.
7. Black Hole –
an object so
massive and
dense that not
even light can
escape its
gravity.
8. Coronal
streamer-A wisp-
like stream of
particles that
gradually moves
away from the
Sun and becomes
part of the solar
wind.
9. Coronal holes -
are areas of the
Sun's surface that
are the source of
open magnetic
field lines that
head way out
into space.
10. Photosphere -
imaginary
surface from
which the solar
light that we see
appears to be
emitted.
11. Sunspot –
temporary
phenomena on
the photosphere
caused by
magnetic activity
which inhibits
convection
forming areas of
reduced
temperature.
12. Chromosphere –
An incandescent,
transparent layer
of gas, primarily
hydrogen, several
thousand miles in
depth, lying above
and surrounding
the photosphere
of a star, such as
the sun, but
distinctly separate
from the corona.
13. Filament – are
formed in
magnetic loops
that hold
relatively cool,
dense gas
suspended above
the surface of the
Sun.
14. Corona hole –
areas where the
Sun's corona is
darker, colder,
and has lower-
density plasma
than average.
15. Convective Zone
– the range
of radii in which
energy is
transported
primarily
by convection.
16. Radiative Zone –
In the radiation
zone, energy is
transported by
radiation.
17. Core – The core is
the source of all
the Sun's
energy. The Sun's
core has a very
high temperature,
more than 15
million degrees
Kelvin, and the
material in the
core is very tightly
packed or dense
