A Science Daily writer gives his take of a new paper by K. A. Alamo-Martínez et al. about unimaginable numbers of globular clusters, here:


They reference the article here: http://iopscience.iop.org/0004-637X/775/1/20/ and they have the full paper for $9. Not bad compared to four or five times that for some journals, but too rich for my blood. Partly, I don’t really understand most of the details. Still it I get the magnitude, and the implications are awesome. (Awe is good.)

These guys write it up too:


Basically, if anyone notices this and cares to enlighten me, I’d appreciate the lesson. The technical, quantitative details (and jargon) in the astrophysical journal article are just a bit beyond my own study, and a bit farther than I want to pursue, at least at the moment. 

I really despise dark matter. It is too magic. Still, things like this are pushing it past speculation, and into the realm of needing to better figure it out so we can more directly investigate it. I’m not sure what to make of the clusters and the density of dark matter. To some extent it seems obvious, but it also seems a bit convenient. As in convenient enough to where we just might face-palm soon a realize something that will seem obvious after we figure it out. 

As to globular clusters by themselves, well, wow. Think what it would have been like to have grown up on a planet (as unlikely as one might be, especially a habitable one) deep in a dense globular cluster where the night sky is nearly as bright as the noonday sun. 


And the wiki article needs to be updated: http://en.wikipedia.org/wiki/Globular_cluster Still, fascinating. Loads of information.
