Our Solar System
This group of planets is situated on the outer layer of the solar system past the asteroid belt.
The Gas Giants
This iconic constellation consists of 7 stars and takes the shape of a ladle.
The Big Dipper
This was the first man to walk on the moon.
Neil Armstrong
These celestial bodies form when a massive star's gravity is too great and collapses in on itself.
Black Holes
This is what larger stars undergo and the end of their lifespan.
Supernova
This dwarf planet used to be a traditional planet before being reclassified in 2006.
Pluto
This constellation is easily recognizable by the three stars situated in a line like a 'belt'.
Orion
This was the first satellite ever successfully put into orbit.
Sputnik 1
This is the closest galaxy to our own.
Andromeda Galaxy
This is what most small to average size stars become once they reach the end of their lifespan.
Dwarf Stars
This planet has the most moons orbiting it out of every other planet in our solar system.
Saturn
This constellation is seen as a symbol of balance and the scales of justice.
Libra
This rocket was the largest rocket NASA ever built.
Saturn V
Extremely bright galaxies powered by supermassive black holes.
Quasars
These celestial bodies form when massive stars collapse after a supernova, but don't fully collapse in on themselves to form black holes.
Neutron Stars
The planets were originally named after Roman gods, except for this one.
Earth
This constellation is regarded as the closest one to Earth.
Centaurus
This satellite launched in 1977 is the farthest man-made object from Earth, with the goal to reach one light day away from Earth.
Voyager 1
These sections of the universe are massive, empty zones of darkness that contain significantly fewer stars and galaxies than other regions in the universe.
Supervoids
These projections from our Sun are what cause auroras on Earth.
Solar Winds
This asteroid ring lies beyond even Neptune and encircles our entire solar system.
The Kuiper Belt
This is the largest recognized constellation, spanning 3.16% of the night sky.
Hydra
This rocket was the smallest orbital rocket launch ever.
Japan's SS-520-5
The discrepancy of why we haven't seen any forms of extraterrestrial life despite the vast number of stars and potentially habitable planets.
The Fermi Paradox
This hypothetical celestial body forms when a neutron star collapses, and act as an intermediate stable state between neutron stars and black holes.
