As Douglas Adams had the Hitch Hiker's Guide to the Galaxy observe wryly, space is really big. You might think it's a long way to the chemist's shop, but that's peanuts compared to space. Or something like that... In that vein, it is likely, without much question, that our Sun really is the biggest thing in your, my and everyone's little lives.
We know that most life on Earth derives its energy ultimately from sunlight. And while the Sun will eventually - a few billion years hence - have consumed too much of its fuel to sustain the outward expansion against gravity, will collapse to a tiny dense dwarf star then, for reasons I cannot be bothered to Google now, expand in size out to the orbit of Jupiter, consuming Earth and the inner planets, for now, we generally have a pretty positive view of how important Sun is for us (sunburn warnings notwithstanding). Therefore, it must have come as a surprise to many to read recently that, on account of a forthcoming solar storm, we were all doomed. What do you mean, what's a solar storm? And why, on its account would doom be forthcoming? Ah, you need to read the most excellent ScienceBlogs article on solar storms:
(This is the kind of post I would expect to see over on e-clecticism, so hopefully jono will forgive me for this parking of scooters on his lawn!)
So, the magnificent Hubble telescope is 20 years old. For me, the Hubble and the images it produces of deep space (and, hence, the distant past) are one of the Wonders of the Modern World. A truly extraordinary technological and scientific feat. The Grauniad newspaper (ok, The Guardian) has an excellent and interesting narrated slideshow (from yesterday) about Hubble and its discoveries here. Apologies that you have to follow a link, but there didn't seem to be an option to embed the article (and I'm ham-fisted about this stuff, if it isn't obvious). But go on, have a look, and gawp, open-mouthed, at the deep space pictures produced by this massive peeping tube in space. It is staggeringly difficult to comprehend the spatial scale of some of these structures in deep space, when the narrator says something about the little blobs on one image being of the order of a light year across.

And if you really like these views of deep space, you can see much, much more here, on the NASA Hubble site.
One or two of the blogs I follow often feature space-related posts (you know who you are!) which I really enjoy, having grown up in the era when manned (they were all men then) space exploration consisted of more than orbiting the Earth (I speak as someone whose parents got him out of bed as a pre-school child to see the first Moon Landing in July 1969!). Space exploration was a significant part of the zeitgeist back then - even mashed potato adverts used alien space explorers to advertise their wares:
("For mash, get Smash".

And I guess that, as a young child, my early exposure to NASA's finest was the reason I was so obsessed with the Clangers (if you are under 30, think "knitted space people living on a bare rock planet, fed green soup from a crater by a soup dragon"). One element of the Clangers that resonated with my young mind was frequent references to "the music of the spheres", a haunting space concert that drifted through the ether (it was a vacuum, so how did that work?) and was enjoyed, concert-like by the assembled Clangers. It was only when I was much older that I realised this was a very grown-up reference for a children's programme, as the Music of the Spheres is a ancient philosophical concept, Musica universalis (literally universal music) in which the relative proportions in the movements of celestial bodies—the Sun, Moon, and planets—are regarded as, in th words of Wikipedia's entry, "a form of musica (the Medieval Latin name for music). This 'music' is not literally audible, but a harmonic and/or mathematical and/or religious concept." Perhaps an ancient Greek idea to start with, it has been persistent in history - Apparently, Johannes Kepler used the concept of the music of the spheres in his Harmonices Mundi in 1619, where he related astrology and harmonics.
Although the Music of the Spheres was not intended literally to be music, this is not so in the Clangers! Their ears were tuned to hearing the music of the spheres and, in the very final episode of the Clangers (which you can see below or here on Youtube), three Clangers in a wonderful "music boat" spacecraft assemble a load of instruments and play a concert of the music of the spheres in space. Heady stuff for a young mind already immersed in Apollo missions!
So, with all that background and baggage, I fell hook, line and sinker in love with the Solar Beat project, a website produced by White Vinyl Design, and which looks like this:
Solar Beat transforms the Solar System into a music generator, a literal Music of the Spheres - each planet is assigned a different note, which is played each time it completes a circuit and, as each takes a different time to complete a circuit around the Sun, the resulting tunes are variable, occasionally melodic and pleasing! You can play with Solar Beathere. And I say "play" as you can change the rotation rates to slow down or speed up the generation of notes. I sometimes just set this running in the background while I am working on the PC, running quite slowly and producing not-quite random music of the spheres!
Incidentally, the Music of the Spheres featured in David Tennant's Dr Who, in a short episode of that title (see below), created in 2008 to support a Dr Who music event at the Albert Hall as part of the Proms (distinguished for Dr Who fanboys and fangirls, if you watch all seven minutes of it, by closing with the original, and better, Ron Grainger version of the theme tune!!!).
