Astronomers like me who stick their toes into the waters of public outreach get asked lots of questions, but the most common one is
"Do you believe in aliens? " "How do I get a job in astronomy?"
There are lots of answers to that question -- I posted one years ago, and it still holds up IMO -- and Tony Darnell over at Astronomy Buff just posted his take on it as well. I can't find too much fault with what he wrote; it dovetails with what I wrote, too. With new observatories going online, we'll be flooded with far more data than any 100 astronomers can sift through. I hope that the folks in charge of such projects just go ahead and make the data public; that way hordes of online readers can find the gems in the noise.
