Celestial Bodies & Pulsars

By Ryan Lacy, Laura Hayes,
& Michelle Stewart

What is a Pulsar?

Pulsars are Neutron
stars that emit
beams of light &
radiation that shoot
out at opposite ends.
Since Pulsars rotate
on an awkward axis,
This explains why we
see it blink on and
off.

Discovery

Pulsars were discovered in
1967 by astrophysicist
Jocelyn Bernell while she
was conducting graduate
research. She discovered it
when she noticed radio
frequencies were blinking
on and off.

How do Pulsars relate to Earth & Space?

Pulsars relate to the CLEA
computer program lab we did
about pulsars. Explaining what
scientists do when they find one
and how they interpret them.
Generally, pulsars are also one of
the many celestial bodies that we
study in space.

How are Pulsars important to Earth & Space?

It tells us more about the nature
of stars and act as probes to let
us investigate the universe.
They were deemed important
around the time of its discovery
because they thought it was
extra terrestrial life sending
messages out into the universe.
It was proven later they were
just another breed of stars.

StarS
Stars are in a sense ball of gas The properties of stars
that burns to make there were discovered by Ejnar
signature illuminating effect. All Hertzsprung and Henrietta
held together by gravity. Leavitt throughout the 19th
century.

Mizar and Alcor. The
binary star system
Polaris
that is part of “The
Big Dipper”
Stars were first constellation.
recognized by the
ancient Egyptians
circa 2,500 A.D.

Betelgeuse. The star on
Orions left shoulder.

Nebulas
B33 Orion Nebula
Nebulas are a cluster of
gases, stars, and dust.
Most common are a
result of the death of
stars.

Eagle Nebula
Contains necessary
materials to make stars,
planetary/solar systems,
and other celestial
bodies. The life giving
phenomena. Eskimo Nebula

Comets
Comets are chunks of iron and
rock, much like asteroids, with a
ice filled core. The ice is most
likely from other sources such as
planets from the universe that Haley’s Comet. A comet we
broke off. are familiar with when it
fly’s by Earth every 75 years.

The thing that makes comets
comets is when it flies by a
heat source, such as the Sun,
Shoemaker-Levy 9. A comet that was
and the ice starts to melt discovered in 1993. In 1994 it broke up
making a misty tail of water into fragments by Jupiters gravity and
vapor that in some pictures crash into Jupiter making craters the
size of Earth
