Seth talks about the newly found ~5 Earth-mass planet and how one can
use the Sun's gravity to lens Radio waves for SETI by sending an
observation probe to 550 A.U.'s from the Sun. Although this isn't
exacly news, this impressive-sounding mission would utilize

"thirty thousand times the collecting area of the gargantuan Arecibo
Radio Telescope in Puerto Rico. It could detect a transmitter with the
power of your local TV station at a distance of a hundred light-years,
even if the alien broadcasters weren't beaming our way."

(Hmmm, all that and only less than 1% of the galaxy can be searched for
leakage? Hard business this SETI schtick!)
