Newfound black hole is the closest one to Earth we've ever found


Oct 22, 2019
"How to see HR 6819 While you may not be able to find the black hole while stargazing from your backyard, skywatchers in the Southern Hemisphere can see the stars in the HR 6819 system in the night sky without the help of binoculars or a telescope. "We were totally surprised when we realised that this is the first stellar system with a black hole that can be seen with the unaided eye," Petr Hadrava, a scientist emeritus at the Academy of Sciences of the Czech Republic in Prague and co-author of the study, said in the statement."

Good star chart by SkySafari showing the location and fifth magnitude so visible to folks with darker skies. After digging a bit into other reports on this potential BH. My observation, a 4.2 solar mass BH has a diameter of 1.6582E-7 AU and angular size of 5.4E-10" at 307 pc distance or 1,000 light-years. Schwarzschild radius is 12.404 km. https://www.scientificamerican.com/article/astronomers-may-have-found-the-closest-black-hole-to-earth/

is that the same one as out the back of centaurious near Sagittarius its been there a while. black hole are fascinating. they consume all things. like they are the seeds of the universe. and after they grow and leave this universe and return back to their home and only when mature return to this asteroid and deposit their seeds again to which we call a universe. I have maps if you want.
