Staring Down the Barrel of a Black Hole

At https://blogs.discovermagazine.com/crux/2018/07/12/what-is-a-blazar/ … a blazar is like staring down the barrel of a black hole, we re informed ….

   …. this is a refeence to the news that a neutrino has been captured in a detector at the South Pole (reported a few days ago) – apparently with an origin in a black hole (or that is the mainstream theory). At the centre of a particular galaxy there is huge black hole and it has become very bright – shooting out colossal jets of material that travel close to the speed of light. Scientists call this a quasar. Earth facing quasars are known as blazars (as the angle is different).

At http://blogs.discovermagazine.com/2018/07/16/black-holes-active-galactic… … an update sent in by Jovan. Why do some black holes look different to others is the query – and the answer is given. One kind of black hole is created by a dying star after undergoing supernova, collapsing in on itself. Another kind of black hole is associated with quasars and blazars. Apparently, we are told, black holes were predicted by Einstein's theory of relativity – even though Einstein himself was dubious of their reality.

At https://wattsupwiththat.com/2018/07/18/astronomers-witness-a-star-devour… …. we've had black holes eating stars and now we have a star chomping on a planet. What was actually seen over several decades of sky observation was a star dimming and brightening on several occasions. In January of 2017 it did it again and NASAs Chandra X-Ray Observatory recorded X-ray emissions coming from the star and after analysing 14 hours of data they found a lot of iron in the star – which may have been recently captured. This was interpreted as the core of the swallowed planet – if the amount of iron detected was recent.
