  Bennu: a new era in space exploration
  http://www.spiked-online.com/newsite/art...tion/18619
  
  EXCERPT: Physics is having a moment. Almost two years ago, the world stopped in awe as the Philae lander became the first module in history to soft-land on a comet. The recent discovery of gravitational waves has also made ground-breaking progress in the work Albert Einstein began a century ago. And, most recently, NASA has announced its plans to send a mission to Bennu: a 500m long, rotating cluster of dust and rock which swings into sight of Earth every six years. The mission requires an investment of one billion US dollars and will take seven years from its launch to return. So what makes Bennu worthy of a place in the canon of recent scientific breakthroughs...

  NASA Observatory Reveals a Dark Zone --"Swarm of 10,000 Black Holes Have Migrated to Heart of the Milky Way"
  http://www.dailygalaxy.com/my_weblog/201...-core.html
  
  EXCERPT: A swarm of 10,000 or more black holes may be orbiting the Milky Way's supermassive black hole, according to observations from NASA's Chandra X-ray Observatory in 2015. This would represent the highest concentration of black holes anywhere in the Galaxy. These relatively small, stellar-mass black holes, along with neutron stars, appear to have migrated into the Galactic Center over the course of several billion years....

  The American Osirisrex spacecraft has arrived at Bennu, which looks just like similarly small (1 km, about twice as big) Ryugu, where a Japanese spacecraft currently is.

  This little animated gif (from NASA) consists of telescopic photos taken about one-a-day since the middle of October, as Osirisrex approached little Bennu. (A microworld!) The last photo is from about 200 miles away.
  
  I'm speculating that if these little objects with microscopic gravity are rotating, centrifugal 'force' gives them equatorial ridges. So maybe this oblate-spheroid shape is characteristic of very small rotating bodies.

  Yeah, has that similar "pillow" look of 162173 Ryugu as the probe approaches.
