Astronomy seems to be the only thing I can write about

I just found an old physics paper that I did for extra credit last year (Mr. Garcia gave 10 extra credit points to anyone who wrote a little 1 page paper about the supernova that happened in M101 last year). I must say, it was a very good paper! It's very short, but in my opinion, it is rather good. In case, by some chance, you would like to read it, here it is:

From Stardust to Stardust by Jacob Block

21 million years ago, a star exploded in the outer regions of a spiral arm in a galaxy called Messier 101, nicknamed the Pinwheel Galaxy. The light from this massive explosion, traveling at exactly 299,792,458 m/s, traveled across trillions of miles of intergalactic space, and a few weeks ago, managed to land in one of the telescopes on a little blue planet in the outer rim of the Orion spur of the Perseus spiral arm of a galaxy called “the Milky Way” by the natives of this little blue planet, which made the native astronomers of this world very happy. The star, more precisely a stellar corpse, was a white dwarf. This particular white dwarf had a companion star, which was about to die, and so that star was becoming a red giant. As it swelled up, the surface of the other star got closer to the white dwarf. It got so close that the gravity from the dense little white dwarf actually started pulling material off the companion onto its surface. It kept doing this until it got to the mass of 1.38 times the mass of the star this little blue planet orbits, named the Sun by its natives. Once it reached that critical mass, the atoms of the material on the surface of the white dwarf started to fuse together in a process called nuclear fusion. Fusion happens in normal stars, but is contained in their cores, but in these cases it is not in the core, it is on the surface. So, it exploded in a type of stellar explosion called a supernova, specifically classified as type 1a. The pressure of the explosion caused the atoms around the star to fuse together, even past the element Iron, which doesn’t like to fuse together on its own, and created all of the elements in the periodic table, from Hydrogen to Uranium. The “ash” of this explosion is called a nebula, in this case a supernova remnant, like the Crab Nebula in the Milky Way. The stuff in the nebula is mostly hydrogen and helium, and as time passes, collapse under gravity into new stars, and new planets with the possibility of new life, all because one star got to massive to contain itself. 

Sorry about the weird font, I copied it from the word processor. 

My favorite thing about the paper is that I wrote it from the point of view of an objective observer, not a native of earth.

Conceited post is conceited.
