So too does the gas involved in the production of stars. The Hubble Space telescope has looked for the origins of a stream or ribbon of gas that stetches halfway around the Milky Way. Observations indicate it was stripped from clouds of gas millions of years ago. These are the Magellanic Clouds, two small galaxies that orbit our galaxy.
At http://phys.org/print295252215.html .... some ten to forty tons of meteor dust enters our atmosphere every day - usually as a result of the Earth's orbit passing through the leftovers from a comet's passage. Comets, when approaching the Sun, out-gas a considerable amount of material, varying in degree from one comet to another. This leaves behind a trail that at first is dense and ribbon like, but over time disperses and becomes less of a problem.
At http://phys.org/print295018965.html ... the Big Bear Observatory NST telescope has discovered new features on the face of the Sun - and the link has some images to show what was seen. Photgraphs of never before seen details of solar magnetism, the piece continues, but it is unclear if this is really new stuff or some kind of press release as they are upgrading the telescope and probably recycling old news. Anyone interested in what happens on the Sun will be interested in having a look.
'The Lost Star of Myth and Time' by Walter Cruttenden, St Lynn's Press, Pittsburgh:2006 ... is based on the idea there is a binary system that links the orbit of Sirius with that of our Sun. Since the space age kicked in, and powerful telescopes began to scan the universe, it has been realised up to 80 per cent of observable stars form one of a binary pair (or one of a more complicated system involving more than two stars). Hence, the idea we live in a binary system is not of itself controversial - or shouldn't be.

This is where the so called Lazarus comets come into the equation - dead comets raising hints of life by brief bursts of activity, the subject of a recent paper in Monthly Notices of the Royal Astronomical Society.
Mainstream media and NASA have gone quiet but over at http://tallbloke.wordpress.com/2013/03/05/andrew-cooper-were-the-recent-... ... comments are still coming in 5 months after the posting was uploaded and it concerns the possibility a near earth flyby of an asteroid or dark comet may have had a number of smaller companions, one of these being the Russian meteor that exploded above Chelyabinsk.

At http://phys.org/print293984345.html ... we have the IRIS mission's first look at the Sun's interface region. This is a very exciting mission which will provide science with lots of information on how the Sun may really work - observational rather than theoretical. First images show a multitude of thin, fibre like, structures. There is a constrast in density and temperature at the Interface and spots that rapidly brighten - and just as rapidly, dim. This is thought to be due to how energy is transported and aborbed at the Interface region of the Sun
An interesting story at http://phys.org/print293895074.html ... which is open to some conjecture - I think (bnut may be not). A paper in Nature tells us about a Martian meteorite in Ottawa that has been dated much more recently than previously allowed. Although the meteorite itself was made of older material, crystals growing on the rock prior to its launch from Mars (before ending up on Earth) were growing just 20 million years ago - which is extremely recent in geological terms.
