Transcript of Supernova
A supernova is an exploding star that can become billions of times as bright as the sun. The exploding star can outshine the entire galaxy! The explosion throws a large cloud of dust
and gas into space. The mass of the material
may go larger than 10 times the mass of the sun. There are 2 types of supernovae.
Type 1, and type 2. Before you know what type 1
is, you need to know what a binary star is. A binary star is a pair of stars that are close together,
and that orbit around eachother. Type 1 supernovae most happens in binary stars.
If the two stars are close enough to eachother,
the smaller star gains mass from the pul of gravity on
the larger star. When the smaller stars gains enough
mass, it collapses, then explodes.
Type 2 supernovae happens when a star begins to burn out, and its core quickly collapses. When this happens, energy is suddenly released. This forms a supernova!

Some scientists say that supernovae
might have created some elements
such as iron, gold, and uranium. inchara4u.wordpress.com optcorpt.com lancs.ac.uk spacepictures.org spaceflightnow.com cfa-www.harvard.edu lotcchicago.wordpress.com in 1054, chinese astronimers found a
supernova so bright it was visible
during the day! it left behind a huge cloud of gas called
the crab nebula, which you can still see today. williams.edu I got all my sources from
the NASA website,
www.nasa.gov/worldbook/supernova another cool fact!
