What words are in the space word search?
Space puzzles use real astronomy vocabulary: the eight planets, nebulae, comets, quasars and pulsars, eclipses, equinoxes and constellations. There are no film or franchise names — just the sky as astronomers describe it.
The full space word bank has 40 words. Each puzzle picks a set from this list, so no two grids are quite the same:
ASTEROID · ASTRONOMY · AURORA · CLUSTER · COMET · CONSTELLATION · COSMOS · CRATER · ECLIPSE · EQUINOX · GALAXY · GRAVITY · HORIZON · JUPITER · LUNAR · MAGNETAR · MARS · MERCURY · METEOR · MILKYWAY · MOONLIGHT · NEBULA · NEPTUNE · ORBIT · PHOTON · PLANET · PULSAR · QUASAR · ROCKET · SATELLITE · SATURN · SOLAR · SOLSTICE · SPIRAL · STARLIGHT · TELESCOPE · URANUS · VENUS · VOID · ZENITH
Who is this theme good for?
Ideal for curious adults, stargazers and anyone who enjoys words with unusual letters. Longer words on the list such as CONSTELLATION, TELESCOPE and ASTRONOMY make the search feel satisfying.
A solving tip
Q and Z are rare in a grid, so QUASAR and ZENITH are quick wins whenever they appear. Look for the letter, then check all eight neighbours for the second letter of the word.
