Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?
This is your opportunity to ask questions. No question too simple or too silly.

Notes -
Once is happenstance, twice is coincidence, three times is enemy action. Due to the almighty youtube algorithm I have watched somewhat more astronomy videos than usual.
Tabby's Star - 1,470 light years from the sun, dimming from time to time. Have some decent explanations involving exomoons and some indecent involving alien dyson sphere.
Przybylski's Star - 356 light years away from us, very unusual composition. It is full of short half life elements - so either something produces them or something put insane quantities of them there. Or it is aliens dumping ground.
Methuselah star - 200 light years away from us, at a time thought to be older than the universe, but now is revised down, still one of the oldest stars found. Probably not that noteworthy because due to the exponential change in main sequence life with linear change of the mass.
The sun - 8 light minutes aways from us. Notable with being the only place we know that has life (my opinion whether the life is intelligent or not depends if I have visited twitter yet or not any given day). And Venus - I think it is the most interesting place in the solar system right now after earth.
So do you think that our neighborhood is somewhat unusual, or there are huge gaps in our knowledge?
Any other interesting thing in the space close to us?
What's so interesting about Venus vs e.g. Enceladus?
