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.

Dust grains and planet formation

Funny thing, I was reading some Electric Universe stuff the other day and how they reckoned the planets formed, and here we are, at http://phys.org/print273315818.html ... in one of those strange quirks or coincidences, a story of Japanese researchers coming to a similar conclusion (without the electricity) - planets formed by the acretion of dusty grains colliding and binding to each other and becoming asteroids, moons, planets and so forth.

Tom Findlay book

Tom Findlay, who has talked at various Thunderbolts conferences, has written a book, and at the moment you can download it for free - go to www.newtoeu.com (in pdf format). Later, it will appear as an eBook and in a printed version. The subject is the universe and how electricity plays a role - as well as gravity.

Gary's Pumpkin Pie and black holes with plasma jets

At www.newscientist.com/article/dn22509-pumpkin-pie-craters-on-mercury-are-... ... the link was forwarded by member Gary and the story is derived from data sent back by NASAs Messenger spacecraft. The weird shapes and cracks are caused by lava cooling and contracting - or that is the explanation. What do you think?

Mercury and the Sun

High frequency flux transfer events have been detected near Mercury - is this evidence of the magnetic reconnection process? - see http://phys.org/print272050738.html ... the discovery comes from measurements taken from data sent back by spacecraft that are currently orbiting Mercury. These flux transfer events are stronger and larger and more frequent than anything seen occurring between Earth and the solar wind - but Mercury is a lot closer to the Sun.

Van Allen Probes

At http://phys.org/print271927309.html ... NASA launched twin satellites in August 2012, the Van Allen probes. The idea is to study the magnetosphere and how the solar wind interacts with it. After just 3 months scientists are already excited by the data they have received - papers and publications are in the pipeline. The probes are designed to relay back informatover over the couple of years. Apparently, some solar storms do not effect the magnetosphere at all - and on other occasions they cause the magnetosphere to shrink.

Venus and Sun Spots

An interesting post for one and all at Tall Bloke's Talk Shop - see http://tallbloke.wordpress.com/2012/11/06/warren-de-la-rue-balfour-stewa... ... sun spots appear to grow on the face of the Sun according to the positions of the planets Mecury and Venus as they orbit the Sun. Balfour Stewart was head of solar research at Kew Observatory in the late 19th century and the paper itself dates to 1872. Why does Venus in particular play a leading role in the production of sun spot activity?
