It's not how many that get me excited, it's the discovery of galaxies so ancient they were formed "shortly" (300-400 million years) after the cosmic dawn
The Milky Way in comparison was 14 BILLION years later (vs half billion)
Any life with a few billion years headstart over humans might have figured out FTL travel or at least FTL communication (massless)
adding: yup, I screwed up on Milky Way age vs cosmos age, cosmos roughly 14 billion years, Milky Way first stars roughly 1 billion years after cosmos started
