Transcript of SUPERNOVA!!!

SUPERNOVA!!! Supernovas are often over 3,000 light years away from Earth! :P Supernovas are massive in size, some are over ten light years across. A supernova remnant is even bigger upwards of 50 million light years across. :D The first supernova was discovered the first explosion almost 10 million years ago. A supernova is a new explosion of very large notes. Some of the heavy element production is in nuclear fusion before the supernova explosion. Interesting Facts:
Supernovas put iron into your blood.
They can go at a speed of 9,000 to 25,000 miles per second! :O
Supernovae produce a shock wave that compresses clouds of gas to aid new star formation.
The explosion throws a large cloud of dust and gas into space. The mass of the expelled material may exceed 10 times the mass of the sun.
Supernovae are stars that burn out rather than fade away. They end their evolutions in massive cosmic explosions. Supernovea cores are made of Iron and then it goes (from the core to the outside layer)- silicon, oxygen, neon, carbon, helium, hydrogen. And that is what a supernova is made of... :]
