Is the last sentence of this paragraph really awkward?

Just our galaxy alone contains approximately a hundred billion stars, and most stars have its own planetary system. In the observable universe, there exist approximately a hundred billion galaxies. That means there could be at least one sextillion stars out there and this astronomical number is only the observable universe. Our galaxy is a hundred thousand light years across; astronomers have only scanned at most a hundred light years from the solar system, which does not even amount to one percent of our galaxy. To say that there is not a single planet habited by intelligent life forms in the many sextillion stars is beyond myopic.
