Explodie Things
Just because it has stars does not mean it's astrology
Holst's got nothing on these planets
I spent two hours on the NASA website and the only thing I got was ideas for this category
Things I just want to talk about
100
This explosion started as an infinitesimal point that exploded and created the universe.
The Big Bang
100
This star can be found in the handle of the Big Dipper and is also known as the Northern Star.
Polaris
100
This moon has cantaloupe terrain and is Neptune's largest moon.
Triton
100
This space probe launched to orbit Jupiter in 2011 and its mission is set to end in 2025 after being extended for 4 more years.
Juno
100
These are described with Hubble's Tuning Fork diagram where they are described as elliptical or spiral.
Galaxies
200
These types of explosions are caused by a white dwarf star gaining too much matter in a binary system or when a high mass star dies.
A Supernova
200
This constellation has the star Betelgeuse and Rigel but neither are in it's namesake belt.
Orion
200
This planet has the volcano Olympus Mons and the rover Opportunity landed on its Meridiani Planum.
Mars
200
This probe launched to orbit Saturn in 1997 and ended its mission in 2017 when it was crushed under Saturn's gravity in the Grand Finale.
Cassini
200
This phenomenon occurs around a black hole due to difference in gravitational potential (think Interstellar).
Time Dilation
300
These objects in space are caused by the collapse of a high mass star and supermassive types are caused possibly by a chain reaction in the collisions of stars.
Black Holes
300
These types of solar systems contain two stars.
Binary
300
One of this planet's main highlands is called the Ishtar Terra and this planet's day is longer than it's year.
Venus
300
This mission actually had two different probes launched to take advantage of the alignments of the planets known as the Grand Tour. Currently both probes have left the solar system.
Voyager
300
This theory made by Einstein states that space and time are interlinked and is proven by the equation E=mc2.
Special Relativity
400
These objects are surrounded by the accretion disk of a black hole and emit huge quantities of energy.
Quasar
400
This diagram is a scatter plot of stars showing relationships of magnitudes/ luminosities/ temperatures.
H-R or Hertzsprung- Russell
400
The discovery of water on this planet cemented the theory that comets brought Earth its water and one of this planet's features is the String of Pearls.
Jupiter
400
This probe was launched in 2006 to flyby Pluto and its "moon" Charon.
New Horizons
400
Stars will continue with nuclear fusion until this element is made.
Iron
500
This event occurs when a black hole strips the surrounding objects of their matter and into "string" looking streams.
Spaghettification
500
Stars will do 90% of their nuclear fusion in this part of the H-R diagram and it stretches from the upper left to the bottom right.
The Main Sequence
500
When looking for other habitable planets NASA typically looks for planets in this region in comparison to their sun.
The Goldilocks Zone
500
This Apollo mission took this famous picture called Earthrise. 
Apollo 8
500
These tiny moons orbit Saturn and are named after their misshapen look that takes after a food.
Ravioli Moons
