This feed is mostly personal interest; it's NOT my professional writing. There's tech here, yes, but also lots of general science and some politics and weird humor thrown in.

Remember when we all thought there were only 9 (OK, 8) planets?

There are now known to be:

  • 948 confirmed planets around 697 Stars
  • 141 Systems with Multiple Planets
  • 3,588 Kepler Candidates and Confirmed Planets


Extrapolating from the above, there are something like a hundred billion planets in our galaxy alone; which is one of untold billions of galaxies.

For the breakdowns, see this NASA page, plus this update, and this article: http://news.nationalgeographic.com/news/billions-of-earthlike-planets-found-in-milky-way/
