Asteroid Investigations

Japanese scientists propose in the journal Nature Geoscience that a large asteroid struck the Moon in the remote past and created the geological feature known as Oceanus Procellarum (or in common speak, Ocean of Storms). This large basin has a flattened feature stretching 1800 miles and it is being suggested it came about as a result of a collision. Over time, subsequent asteroid and meteorite strikes have blurred he edges of the impact zone - see http://phys.org/print270928754.html

The Sun and the Climate Part Two

In response to the Oct 22nd posting, The Sun and the Climate, the mathematical explanation of Bode's Law may actually have already been worked out - by Robert Bass. He was due to speak at the SIS conference on 'Cosmic Catastrophes - Asteroids, Comets and Planets' held at Fitzwilliam College in Cambridge in 2007, in order to present his explanation of the Titus-Bode Law. Unfortunately he had to withdraw and we never learnt what it was.

The Sun remains quiet - but what will happen to the climate

An interesting post on the quiet Sun can be found at http://informthepundits.wordpress.com/2012/10/11/climate-change-and-the-... which was reposted on Tall Bloke's Talk Shop at http://tallbloke.wordpress.com ... interesting times, as they say.

Red Giants

At www.dailygalaxy.com/my_weblog/2012/10/ (scroll down page to October 13th) or www.dailygalaxy.com/my_weblog/2012/10/the-mystery-of-red-giants-in-the-u... ... apparently, a group of nuclear physics theorists are claiming they have solved the mystery of the red giants - a class of stars they say that did not fit into the consensus model of the universe. Since the Big Banged the universe has been evolving and one of its major components is carbon 12 - but how did it get here?

Loopholes on the Sun

At http://phys.org/print269077571.html ... a paper in the journal Solar Physics is based on data gleaned from the Hinude telescope, which is proving to be such a boon. Whereas 'defenders of the faith' might airbrush aside what is not known with a simple flourish of the arms and mouth, scientists are actually pushing away at the secrets the Sun might yet be hiding. For example, in this pape, the 'slow' soslar wind is said to come from a surface full of closed magnetic structures that should #'prevent' gases from escaping.

Voyager One, an observatory, and Einstein update?

At http://phys.org/print268990338.html ... Voyager One may finally have left the solar system - NASA has yet to report and confirm this. There was a huge drop in solar particles hitting Voyager in August. What information is Voyager sending back - the NASA news release is eagerly awaited.

At http://phys.org/print268988645.html ... the UK is contributing 24 robotic arms for the European Southern Observatory in Chile, desigined to observe far away star clusters.

Green Fireballs rocking the night sky

At http://phys.org/print268989752.html ... a meteoroid seen over the UK on September 21st 2012 (there is a short video film) which was very bright for just 40 to 60 seconds, has been analysed by a satellite tracker following a bit of speculation. The idea was mooted that it was a piece of space junk but this was quickly rejected. It was then said to be a piece of an Aten class asteroid which have an orbit that often crosses the orbit of the Earth.

What is happening with the solar wind?

This is the question being asked by an Italian solar researcher - go to Tall Bloke's Talkshop at http://tallbloke.wordpress.com/2012/10/06/michele-casati-can-anyone-expl... ... and if you are interested join in the debate.

Black Holes and mysteries

In the news today (www.space.com for example) we have a star rotating around what is thought to be a black hole at the heart of the Milky Way and yesterday, at http://phjys.org/print268486933.html ... we had the discovery of two black holes at the centre of a globular cluster of stars - which wasn't what was expected in the consensus model.
