A cosmic ray attack on the Earth

Leading on from the previous posting this story comes from www.dailygalaxy.com/my_weblog/2012/12/-december-27-2004-the-day-planet-e... ... which sounds a bit over the top - and probably is. You may not have realised that on December 27th 2004 something so dire occurred but apparently a burst of energy equivalent of half a million years of sunlight was directed at the Earth, a gamma ray burst that ionised Earth's upper atmosphere. The source was in the region of the sky occupied by the constellation of Sagittaurus.

Cosmic Rays

At http://phys.org/print275845800.html ... cosmic rays are thought to originate in massive stars somewhere out in the universe, tiny particles that rain incessantly down from space. Victor Hess, around about a 100 years ago, established during a high altitude baloon flight that the radiation was cosmic in origin. Later, it was suggested the radiation might be gamma rays, an idea that has stuck. These are high energy electromagnetic radiation. Later, it was found the incoming rays were influenced by Earth's magnetic field implying they were charged particles.

Ionosphere of Venus

At http://phys.org/print275843816.html ... NASAs Pioneer Venus orbiter, as long ago as 1978, suggested the ionosphere of Venus had a magnetised state with a large horizontal magnetic field but at other times it was, apparently, unmagnetised with no obvious large magnetic field. Instead, it is thought, or was, it had numerous small magnetic structures known as flux ropes and it was the polar wind, or Venus facing sun spot eruptions, that caused it to have an obvious magnetic state.

Plate Tectonics and the Electric Universe

Wal Thornhill, in a reply to an email, states, there is no such thing as plate tectonics, the magnetic poles move. An external torque might cause the rotational poles to move - but the slight pear shaped geoid is likely as not a hangover from what we call the 'polar configuration' - an interesting answer. Plate Tectonics is of course a big subject and one of those consensus theories that is constantly being jiggled and adapted to new information. Is the theory being shored up or is it robust?

Hiding in the Trees

At http://phys.org/print275123990.html ... the Cluster satellites have shown space plasma is full of turbulent swirls - and so called  magnetic reconnection, it is said, has been detected.

X-Jets

At www.thunderbolts.info/wp/2012/12/09/x-jets/ ... here is the EU perspective on the X Ray jets emitted by the monster black hole.

The Van Allen probes

NASA let out some further news on its Van Allen probes - see http://tallbloke.wordpress.com/2012/12/07/nasas-van-allen-probes-reveal-... ... and it is only 3 months since their launch. They are providing scientists with unexpected information. The Van Allen belts that surround the Earth have been seen to be affected by recent ejections of plasma from the Sun.

The Biggie

This is the black hole that has grown legs and has even got into the vocabulary of comedians, propping up a succession of gags - see www.dailygalaxy.com/my_weblog/2012/11/colossal-black-hole-equal-to-17-bi... ... where there is a nice image from space with lots of orange and yellow flaring. It is so big it doesn't fit the consensus model of galaxy evolution - not by a long shot. Unfortunately, others have recently been found that are equally out of kilter with the consensus.

Massive Flares: Part II

At http://phys.org/print273396491.html ... we are back at the C14 boundary for dating objects, around 35 to 40 thousand years ago. This boundary, it seems, may have been caused by a bombardment of cosmic rays at a time when Earth's magnetosphere failed. Evidence for the event has been found in ocean sediment cores by French researchers. The cores show variations in concentrations of beryllium 10, a radioactive isotope produced by cosmic rays on the oxygen and nitrogen atoms in the atmosphere.

Massive Solar Flares: Part I

At http://blogs.nature.com/news/2012/11/mysterious-radiation-spike-could-ha... ... Ananya Bhattacharya reports, the mysterious spike in atmospheric C14 levels in 774/5AD may be a sign that the Sun is capable of producing solar storms many times worse than anything we have experienced in recent centuries - or currently allowed in consensus science thinking.
