Is the historical event supposed to be the validation, the announcement or the news? Unclear, but the prompt was for one event. When did Kepler validate an exoplanet? He didn’t, it’s about a telescope named after him. Which news and/or validation by the telescope does this acronym refer to? The flavor text specifies one but the acronym itself is ambiguous on that too. So does this actually fit the prompt? Unclear. And there’s a proper noun.

Score 1

Score 3. It reads pretty clearly to me - ‘announcement news’ is plainly tautological but otherwise it hangs together nicely.

Score 3. Very strong first three words but it wanders off at the end.

Score 3, the lack of a main date kinda throws it on me

Now that I’m no longer sleep deprived, I’m amending my rating. If I’m penalizing it for bad grammar, I shouldn’t also penalize it for the ambiguity introduced by said bad grammar.

Score 2 as amended

Score 2 “news” in the headline feels odd to me. Like the news itself isn’t the event

Anything that isn’t war related would be 4+. Gosh, darn; you all seems to kinda just remember wars. Score 4

Score 3 for “announcement news”.

Score 2 - the wording doesn’t feel super clean

Score 4, because it doesn’t change the outcome and it fulfills the perverse incentive of score differentiation. I like this well enough, despite the clumsy wording.
