When a massive star runs out of hydrogen fuel, it begins to collapse in on itself, creating immense heat and pressure. If the core is large enough, its gravity becomes so strong that nothing, not even light, can escape, forming a black hole. Black holes are difficult to detect but distort spacetime so greatly that objects near them would be stretched out in a process called spaghettification. Anything passing the black hole's event horizon would be crushed to infinite density and trapped forever within the black hole. Supernovas occur when extremely massive stars explode at the end of their life cycles, ejecting heavy elements that can seed the formation of new stars and planetary systems.

2. Supernova
When the average star runs out of
hydrogen, it begins the dying process.
But huge stars with very high central
temperatures can use other materials
for fuel when they run out of hydrogen.
They can use helium and produce
oxygen and other gases to keep their
nuclear furnaces going. But when the
star tries to create energy out of an
iron core, the iron breaks up and
explodes within minutes.

3. Supernovas occur throughout
the universe. However,
supernovas are very rare in
our Milky Way galaxy.The lat
one to be seen in our galaxy
was in 1604.An earlier stare
explosion in 1054 was so
bright it could be seen during
the day.

4. Supernovas are not just
destructive forces, however.
The shock waves of heat and
pressure created by the
explosion can cause the birth
of new stars.These new stars
and their planets are enriched
by chemicals created in the
dead star’s core.

5. Black Holes
They are the most
mysterious things in the
universe. It is very difficult to
see one, but most scientists
believe they exist. They
seem like science fiction, but
they are probably real.They
are called black holes.

6. When a supernova happens, it
leaves a core behind.If that
core is big enough, the core
starts collapsing.It collapse so
fast that its pull of gravity
becomes enormous.To escape
from it, something would have
to go faster than the speed of
light.

7. At this point, no light can
escape from it. It becomes
the darkest thing in the
universe. Anything that falls
in can never escape.

8. Black holes are almost
impossible for astronomers to
detect.They were described
and predicted by a genius
named Steve Hawking, who
has spent much of his life
studying thinking, and writing
about this mestery.

9. Trapped in a
Black Hole
Your ship would have to be
reasonably close to a black
hole to be swallowed up. The
gravity gets weaker the
farther away you are.

10. First , even before you were
sucked in, you and your ship
would be distorted and
elongated by what scientists
call spaghettification, or
making an object long and
spagettilike.

11. Once inside the hole, there
would be no escape.
Scientist believe that once
you are inside a black hole,
you will be compressed to a
tiny point of matter.

12. We live in a gigantic swirling
mass of stars called the
universe. The universe is
divided up into galaxies, or
collections of stars, and
recently we have discovered in
the nearest galaxies that there
are many solar systems like
ours.
