You served as an assistant to the late legendary astronomer Hypatia Rubin. Prior to her passing, professor Rubin shared that she has discovered something magical with her advanced telescope, and she has recorded it in her notes - which are locked in a safe behind her portrait.
Due to her age, she unexpectedly passed! Her legacy is locked behind this safe, and many have failed to unlock it.
"The only way we can pry it open is with explosives", says the locksmith, "To do that, we need to first remove the safe from the wall - which will damage the building. We also risk losing valuable items in the safe if the explosion is too strong!"
You are sad to witness your professors legacy disappear in the safe. But you don't give up easily!
As you're working through her room, and clearing out the drawers for clues, you notice a series of star maps with cryptic messages. Except for the last sky maps, all others have words associated with them.
After spending some time deciphering the puzzle, you finally found a way to unlock the safe! What did you do?
