Kepler finds exoplanets orbiting dwarf stars
Worlds without end: In its second life with a limited pointing capability, Kepler has still managed to find more than 700 possible exoplanet candidates, a majority of which are orbiting dwarf M and K stars and are smaller than Neptune.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Nice companion video from the Silicon Valley Astronomy folks, from May 2016:

He has tracking data on 2,869 planets in 2,174 star systems.
As of August, he estimates their are 93 planets with orbits entirely within the habitable zone.
He has plots, tables, and movies on every one of these.
