Palaeolithic Extinctions and the Taurid Complex

Palaeolithic Extinctions and the Taurid Complex, WM Napier, Cardiff Centre for Astrobiology, Cardiff University, available in PDF format for download to the general public but pending publication (which is agreed). George Howard was wondering, a few days ago, if the WISE space mission would find evidence of the Clube and Napier 'remnants' of a comet that broke up in the solar system during the Holocene period and gave rise to various meteor streams such as the Taurid complex.

Hyder Flares

http://wattsupwiththat.com February 24th ... has a guest post that will interest members of the SIS. The subject is the Sun and an enormous magnetic filament that stretched more than one million kim from end to end - visible perhaps in amateur telescopes (but be careful with your eyes). For seven days in a row the filament hung suspended above the surface of the Sun. Charles Hyder, in 1964-7 did a doctoral thesis on these flares and has been the acknowledged expert since then. They are now known as Hyder Flares.

Dark Comets

See http://cosmictusk.com/nasa-mentions-dark-and-dead-comets-for-the-first-time-wise (or simply go to the menu on side bar of the web site) ... George Howard wonders if NASAs WISE mission which is now underway is able to confirm or refute, in part or wholly, the widely dismissed notion and theory of Bill Napier and the British NEO catastrophists.

Supernova

Science News Febnruary 17th (see http://www.sciencenews.org/view/generic/id56425 ) ... new X Ray findings appear to blow a hole in the leading model for the origin of stellar explosions - type 1a supernova events. Astronomers routinely use these very bright events to measure dark energy. The Nature article won't change the interpretation of dark energy but a new understanding is required of supernovae.

Black and Dead comets

February 11th NASA newsflash (see full story at www.jpl.nasa.gov/news/ ) ... a new satellite, launched in December to track NEOs has discovered it's first comet. It will make an extensive survey of comets, asteroids and NEOs and routinely scan the sky with infra red imaging technology that can not only pick up comets ejecting material but also dark comets and dead comets whose whereabouts is unknown and a potential threat to life on the surface of the earth.

Comet Encke and a tail story

RIA Novorosti July 26th 2009 ... according to Russian scientists, in Moscow and St Petersburg, the Tunguska event was caused by cometary material that collided with the earth. The blast was caused by the earth passing through part of the tail of Comet Encke. This is the comet that Clube and Napier saw as a relic of their giant comet that entered the solar system in the Late Pleistocene period. The scientists claim the incredible power of the explosion can be explained by significant differences in the electric potentials - or the charge of Comet Encke and the Earth.

Stars

Daily Galaxy January 25th ... several leading astrophysicists believe there was no Big Bang to bring the universe and time into existence. Instead, they think we are trapped in a thin membrane of space-time embedded in a much larger cosmos from which neither light nor energy can escape - apart from gravity. Accordingly, dark matter is just the rest of the universes that we cannot see because light cannot escape. Neat.

Astronomy and Space

University of Buffalo News June 11th 2002 ... this is interesting though an old post. Research has squeezed evidence out of ice cores to show that sun spots have an affect on climate. Sun spots coincide with strong solar activity - such as we had around the turn of the millennium at the height of the AGW apocalyptic scaremongering. The research found that ice cores also include evidence of dust in the atmosphere (volcanic, cosmic, wind blown etc) and when this happens global temperatures are lower.

The Sun and the Planets

http://tallbloke.wordpress.com ... tall bloke's web blog is all about a thesis that the solar system is an integrated system in that as well as the sun influencing the planets the planets themselves also effect each other. In fact, he suggests their effect on the sun causes its complicated motion around the centre of mass in the solar system - which modulates solar magnetic activity and the production of sun spots.
