NASA & Space Agencies
This is the U.S. space agency that studies planets and space exploration.
NASA
This spacecraft is the farthest human-made object from Earth.
Voyager 1
This term is used by the U.S. government instead of “UFO” today.
UAP (Unidentified Aerial Phenomena)
This is the name of the galaxy that contains our solar system.
Milky Way
This planet is the 4th from the Sun and is studied for possible past life.
Mars
This organization also searches for signals from intelligent aliens (not NASA).
SETI Institute
This boundary marks where the Sun’s influence on space ends.
Heliopause
The 2004 “Tic Tac” object was seen by pilots from this branch of the military.
US Navy
This is the closest star system to Earth.
Alpha Centauri
This moon of Jupiter is considered one of the best places to look for alien oceans.
Europa
The scientific field that studies the possibility of life in the universe.
Astrobiology
Voyager 1 is in this region of space between stars.
Interstellar Space
This is the correct scientific meaning of “UAP.”
Unidentified Aerial Phenomena
Even light from the farthest galaxies takes billions of years to reach us, meaning we see them as they were in this.
Past
This planet has a thick red atmosphere and is often called Earth’s “sister planet.”
Venus
This space telescope captures very detailed images of distant galaxies from space.
Hubble Space Telescope
This is the invisible boundary where the Sun’s solar wind slows down and space becomes interstellar space.
Heliopause
These are the main sensors used by fighter jets to detect UAPs (they combine heat and light detection).
Infrared Cameras / Radar Systems
This is the unit used to measure very large distances between stars (light travels this in one year).
Light-year
This planet has the largest volcano in the solar system called Olympus Mons.
Mars
This is the branch of physics that describes gravity using space-time curvature.
General Relativity
This is the expected time it would take Voyager 1 to reach the nearest star system at its current speed (rough estimate).
Tens of thousands of years
This is the official meaning of “unidentified” in UAP reports—it does NOT mean alien.
Not enough information to identify the object
This is the theory that explains how the universe began and is still expanding today
Big Bang Theory
This is the planet with the strongest winds in the solar system (up to 2,000 km/h).
Neptune
