\o/ Those my friends are victory arms of epicness!
I just found out that I'm going to be doing a semester on Stellar Evoloution.
How excited am I? Very.
So let's learn about The Cat's Eye Nebula.
The Cat's Eye Nebula is found in the constellation of Draco. It is a planetary nebula ( an emission nebula [a could of ionized gas that emits light of various colours], consisting of a glowing shell of gas which forms when certain types of stars die.) It's called a planetary nebula because it is similar to what giant planets look like when you view them through a small telescope.
Anyway, structure wise it is one of the most complex nebulae known and it was discovered by William Herschel in 1786.
The core radius is 0.2ly ( one light year is measured as equal to just under ten trillion kilometres).
I won't go into to much more detail because then it becomes a whole lot of complex mathematics and can be really, really confusing.
So there you have it. The Cat's Eye Nebula.
