How the crowd plays it
"Hubble Space Telescope" is what this prompt harvests from almost everyone — that reliability is what makes rarity measurable. Even "Newtonian telescope", the connoisseur's decoy, is banked at just 15 points: the mirror has seen it a thousand times.
The deep water of this prompt belongs to answers like "Catadioptric telescope" (85). Rarer still is "Radio telescope", the One in a Noillirk gem: find it under a 25-second clock and a single prompt has carried you a full kilometre down.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In science, that means remembering that work the problem backwards, the way real science often happens: start from the phenomenon and reverse-engineer the name. The mirror rewards reasoning, not just recall.
