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?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.

StarSStars are in a sense ball of gas that burns to make there signature illuminating effect. All held together by gravity.

Stars were first recognized by the ancient Egyptians circa 2,500 A.D.

The properties of stars were discovered by Ejnar Hertzsprung and Henrietta Leavitt throughout the 19th century.

Nebulas

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

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

B33 Orion Nebula

Eagle Nebula

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 broke off.

The thing that makes comets comets is when it flies by a heat source, such as the Sun, and the ice starts to melt making a misty tail of water vapor that in some pictures

Haley’s Comet. A comet we are familiar with when it fly’s by Earth every 75 years.

Shoemaker-Levy 9. A comet that was discovered in 1993. In 1994 it broke up into fragments by Jupiters gravity and crash into Jupiter making craters the size of Earth
