At www.physorg.com/print221457830.html we have an interesting interpretation of an astronomical event - two neutron stars merge and within mill-seconds, it is said, form a black hole. It can't of course be seen but is thought to happen, even the neutron stars are hypothetical as far as composition is concerned. What is known for sure is that such an event coincides with the formation of a strong magnetic field along the rotational axis which creates a jet that shoots ultra hot matter into space - a gamma ray burst event.

At http://www.scientificamerican.com/article.cfm?id=earth-atmosphere-format... December 2009 ... Krypton trapped in earth's mantle may not have been captured from the Sun - as models predict. It seems to have an origin in carbonaceous meteorites or comets and if this is confirmed bang goes the generally accepted theory.

At http://wattsupwiththat.com/2011/03/10/sol-is-finally-waking-up/ is a reference to the present X-flare and unsettled geomagnetic conditions (details derived from www.spaceweather.com). A flare on March 9th, following on from the big flare in late February, is what has generated the posting, as it sent a CME towards the earth. Funnily enough, or perhaps just a coincidence, two days later we have the Japanese earthquake.

At www.physorg.com/print217764133.html .... huge blobs of plasma known as coronal mass ejections cause probems when they collide with the magnetosphere of the earth. They produce aurorae for example, but also feature in comet tails (no this is not Wal speaking but a scientist from the Oak Ridge National Laboratory), solar wind and much of the spiralling material that appears to fall into black holes. Science is now trying to understand plasma.
