Back to the puzzle

Solution: Stargazing
Answer: NEBULA

Written by The Enigmatologists

Arrange the words within each constellation based on word length and number of points on each star. Write each word around each star, starting at the gap in the star and going clockwise. The letters from connected points should match, and they give you one final clue: "cosmic dust cloud", or, NEBULA.

Authors' Notes

This puzzle started from my love of writing crossword puzzles. There are many ways to incorporate crossword-style clues into a puzzle-hunt-style puzzle, but I hoped this one would be fun and somewhat unique. I was originally going to use flower petals, but the preexisting structure of constellations was too appealing (plus as a former physics student I had to take the opportunity to talk about space/mention the Gustav Bakos observatory).

This puzzle is a testament to the benefit of having people in your life who also love puzzles (or at least are willing to listen to you ramble about them). Special thanks to my dad and my partner for all their brainstorming efforts (in addition to the rest of the wonderful team of enigmatologists).

This (unfortunately) doesn't play into the puzzle, but for anyone curious, the constellations/asterisms depicted are the Big Dipper, Cassiopeia, and Corona Australis.
