Keyword Framework
Vocabulary built for curiosity — real definitions, credible sources, and real-world extensions
Scale
Scale describes how the size or distance of one thing compares to another. In space science, understanding scale is essential because distances between objects are so enormous that familiar units like kilometers become nearly meaningless.

Real-world extension: Scale models of the solar system help engineers plan mission travel times, communication delays, and the fuel budgets needed for deep-space probes.
Orbit
An orbit is the curved path an object follows around another because of gravity. The Moon orbits Earth, and Earth orbits the Sun, because their speeds and the gravitational pull between them stay in continuous balance — a kind of endless free-fall.
Source: NASA Glenn Research Center; NASA JPL
Real-world extension: Engineers calculate precise orbital paths to place satellites in positions needed for GPS, weather monitoring, and global communications.
Gravity
Gravity is the attractive force between any two objects with mass. It keeps planets circling stars, moons circling planets, and atmospheres clinging to worlds. Greater mass and shorter distance both increase gravitational pull.

Real-world extension: Gravity assists — using a planet's gravity to swing a spacecraft faster — have cut travel time and fuel cost on missions to Jupiter, Saturn, and beyond.
Electromagnetic Spectrum
The electromagnetic spectrum is the full range of light, from long radio waves to short gamma rays, organized by wavelength and energy. Human eyes detect only a narrow visible slice; telescopes built for other wavelengths reveal what optical instruments miss entirely.
Source: NASA Science; Space Telescope Science Institute (STScI)
Real-world extension: Astronomers layer infrared, X-ray, and radio images together to build a fuller picture of star-forming regions, galaxies, and black holes.
Telescope
A telescope is an instrument that gathers and focuses light — or other electromagnetic radiation — from distant objects to make them detectable and measurable. Different optical designs are optimized for different wavelengths and scientific purposes.
Source: NASA Science; Space Telescope Science Institute (STScI)
Real-world extension: The James Webb Space Telescope uses a segmented infrared mirror to observe light from galaxies that formed within a few hundred million years of the Big Bang.
Stellar Life Cycle
Stars are born in clouds of gas and dust, spend most of their existence fusing hydrogen into helium, and die in ways that depend on mass — smaller stars fade as white dwarfs, while massive stars end in supernovae or collapse into neutron stars and black holes.
Source: NASA Science; NASA Hubble Site
Real-world extension: The carbon, oxygen, and iron atoms in your body were forged inside earlier stars and scattered through space by their explosions — stellar death is how the universe distributes the elements.
Spectroscopy
Spectroscopy is the study of how matter absorbs and emits light at specific wavelengths. Each element produces a unique pattern of lines — a spectral fingerprint — so scientists can identify what distant stars, atmospheres, and clouds are made of without ever visiting them.
Source: NASA Science; NIST
Real-world extension: The same technique is used in environmental pollution monitoring, food safety testing, and identifying mineral composition in Mars rocks.
Exoplanet
An exoplanet is a planet orbiting a star other than our Sun. Thousands have been confirmed, and scientists search for candidates in a star's habitable zone — the range of distances where liquid water could exist on a surface.
Source: NASA Exoplanet Exploration; NASA JPL
Real-world extension: Detecting exoplanets requires measuring tiny dips in starlight and minute wobbles in star position — a challenge that demanded new instruments and new statistical methods before it became routine.
Rover
A rover is a vehicle designed to travel across the surface of another world, gathering data, images, and samples. Rovers carry sensors, cameras, and sometimes miniature laboratories to study soil, rock, and atmosphere from a distance.
Source: NASA JPL; NASA Science
Real-world extension: The Perseverance rover on Mars has been collecting rock cores being prepared for a future sample-return mission — the first attempt to bring Martian material to Earth laboratories.
Light-Year
A light-year is the distance light travels in one year — about 9.46 trillion kilometers. It is used to express astronomical distances because standard units produce numbers too large to reason about usefully.
Source: NASA Science; NASA JPL Education
Real-world extension: The nearest star to the Sun, Proxima Centauri, is about 4.24 light-years away — meaning the light we see from it left more than four years ago, so we always observe the past when we look at stars.
