Star’s and Nebulas By Eliza Whisler
What is Star? • A star is a ball of gas in space that is really hot. The star is a sun, because the sun is a star. • A nebula is a ball of gases and dust that star’s form from.
Star’s life There is a star lifetime, actually. Star’s are born from nebulas. As they get older, they either die or turn into a black hole, or explode, called a supernova.
Type’s of Nebulas. There are many types of nebulas. One type of nebula is an Emission Nebula that has many colors and is very hot. A reflection nebula is cold and shines light from other nebulas. Planetary Nebula’s are old nebulas (Meaning they have been in space for a while.) and they blow of gas. Dark Nebulas are filled with so much dust the appear to be black or dark. This Reflection nebula. Planetary Nebula It’s RAINBOW Picture Is of a dark nebula.
Fact’s on stars. • An exploding star is called a supernova? • That your horoscope is often named after a constellation. A constellation is a pattern of stars to form a picture with a back round story usually about Greek Mythology. • Most of a star’s life is spent on producing gas • Star’s twinkle because of Earth’s moving atmosphere • The sun is NOT the closest star to earth, it is Promixa Centauri which is located about 4.2 light years away?
Why? • I did star’s and nebulas because I always thought stars were interesting. I didn’t know what a nebula was so I decided it would be interesting to research. I enjoyed learning about Nebula’s and I learned some awesome facts about star’s.
Star’s vs. Nebula contrast Stars Nebula’s Nebula’s are dark Has gas, but not a star Hard to find Nebulas. • Star appear to twinkle • Just like the sun • Sun shows on Earth
Star’s vs. Nebulas compared! • Star’s and Nebula’s are alike because they are both full of gases and have several types. Like there’s a planetary and cat eye nebula and star’s have big red giant and young blue star. They are also seen in the night sky.
What make’s a Star compare to the sun? • Both the star’s and the sun are full of gas. Really, the sun is a closer, average sized star. So if you want to say it like this: There a MILLIONS of sun’s!
Some Pictures! • This is a *Shooting Star! Supernova
Shooting Star’s! • Shooting Star’s aren’t just star’s that are flying in space, they are actually meteorites. Meteorites are small part’s from a meteor or asteroid.
Think about it? Do you think there could be other types of Nebula’s and star’s? Why are star’s little sun’s besides that they have gases? Could we go inside a Nebula? Did we ever send anything into a black hole? (A black hole is a star that died, but did not explode AKA supernova.)
It’s the sad end. Thank you for watching I hope you paid attention!
More information! • That first picture on the other slide was a lie. Ha! So let’s just say this next slide will share some more information!
Finally More Information! • There are 1 septillion stars in the universe. Only 3,000 can be seen alone. • Some star’s are so huge that the sun is a dot compared to them. • Most star’s are 3 billion mile across, while the Sun is only 860,000 miles! • The brightest star is called Sirius. • The Crab Nebula was once a Supernova. • A photo of the Crab Nebula:
Star’s history • Ancient Roman’s always looked at the stars and thought they were rotating Earth, which they aren’t. They play and important part in navigation. They helped to accurate calendars. Today star’s still help direction. People don’t forget the star’s history. Many astronomer’s, such as Galileo and Girodana Bruno.
Constellations. There are many types of constellations. Some are: The Big Dipper, The Little Dipper Ursa Minor, Ursa Major Cancer Crab Gemini Twins Leo the Lion
Now it’s time to use your, Imagination • Think, what if there were star aliens? • Could there be life, even as little as bacteria? • Could star’s center be ice or water? • When the sun dies, could a star replace it?
Ok imagination time is over… • There for,
Now imagine this with Nebula’s so you have to Imagine still! • A Nebula Exploding • Astronauts on a NEBULA!! Or at least floating in it? • Rover going into a Nebula and life is found! • You never know….
