Transcript of Nebula

Nebulas What is it? How is it created? Names Fame & Color Many things thrive in space that you might have
not known. If you do, you will gain information
on what I'm about to tell you about. Nebulas. These
magnificent stars will catch your eye. Let's get started. Now for the most important question, "What is a nebula?" These are stars found in space. A nebula is an interstellar, circulated cloud consisting of hydrogen, gas, plasma, dust, and helium. It absorbs and reflects radiation so it appears luminous and colorful. Nebulas are formed when the interstellar medium ,
which is matter occuring between stars, collapses. It mostly contains separated ions of molecular or neutral hydrogen. Then it clumps
together due to
gravitiational attration
of particles. Why do these cosmic clouds have such vibrant hues? Well, resulting colors can be from stars inside the nebula, radiance, and even elements within the cloud. Nebulae are famous? Depends. Among science I believe, yes, they are. Some prominent nebulae are the Crab, Eagle, Pelican, Ring, and the Rosette Nebula. Titles for these planetary
stars are based on appearance and maybe even after animals it seems. My observation originated from my earlier slide when I stated the names of the Pelican, Crab, and Eagle Nebulae. The Ring Nebula confirms my "named after appearance" inference. Facts Visualize?

www.dictionary.com( Thesaurus) Would not be possible without : Intro Thank You! :) NEBULAE I hope you enjoyed my Prezi!!!!! Clouding your mind with fun facts * "nebula" means "cloud" in Latin
* nebulae have atmospheres
* red giants evolve from stars, and these stars can lose their outer layer during pulsations
* during pulsations matter ,97% hydrogen and 3% helium( with other traces of materials) is released
* there are different types of nebulae,
including planetary, dark, and
supernova remaints Creation Continued . . . The rising attration is dependent on the gathering particles, but only the particles in range. The pressure from the formation gets so elevated that fusion develops. This leads to the making of high electromagnetic radiation. Following, ionization of gas occurs.This is the first stage
of star creation. * ionized gas is plasma Now you know intresting facts, formation, and more. What have I not shown? I am a very visual person. To learn, I need to see, that's exactly why I'm going to show you visual learning. A.K.A pictures! This
is the butterfly nebula. See how colorful it is and the radiant stars shining that also gives the wisplike cloud a hue(color). It's title also pertains to its shape. You can learn just from looking at a photograph, for a picture speaks a thousand words! Visuality Lives Impacted? The discovery of nebulae or nebulas(they are both correct spellings) might have impacted our education of space, but it hasn't impacted our lives in any way. These "species" has uncovered a knowledge of stars. The Orion Nebula, 1,500 light years away, can be seen with just binoculars located in a region titled The Sword of Orion. Nebulas intrest astronomers more then anyone with any other profession, but you must know that I think that we should all be facinated. Were you paying attention?! Are nebulae famous? a.) No, since they have not impacted our lives.
b.) No, because no one is intrested
c.) Yes, because among science they are believed to be (by me)
d.) Yes, but only astronomers are interested Name 3 prominent nebulae mentioned in this Prezi : ______________ , _____________ , ____________ The word "nebula" originated from what? a.) Spanish
b.) Arabic
c.) German
d.) Latin Ionized gas is. . . a.) plasma
b.) 97% hydrogen 3% helium
c.) dust
d.) traces of elements How do nebulas appear colorful? a.) light from the sun
b.) absorbs and reflects light
c.) stars outside the nebula
d.) radiation HINT: POP QUIZ www.oarval.org
