Comet P/2016 BA14

An insignificant, but fairly close asteroid, turned into a 3,000 foot wide comet, grazing Earth at a record close distance. Actually close enough for ground based telescopes to get some pretty neat images of it:

Which always makes me wonder, if we can’t really detect a half-mile wide comet grazing the Earth with any real idea of how big it is, which directly determines how big a threat it is to us, then MAYBE we should invest in technology that would allow us to do a better job doing that than, oh, guessing at life on planets billions of miles away.
