Therefore, creating smaller stars. Smaller stars burn much slower than large stars and thus the stars in the halo are older. I have also read somewhere that the Milky way was about twice as large as previously thought. Thats great, when we collide with Andromeda it will be a much bigger splash than planed.

Κάθε τέτοια εικόνα μοιάζει με τρύπα στο χαλί του κατανοήσιμου: δείχνει, σαν δάχτυλο παιδιού, μια άγνωστη περιοχή του κόσμου, προς την κατεύθυνση της οποίας δεν είχαμε σκοπό να κοιτάξουμε.

I have friends who have been promoting the concept that there is an extended cold dust emission probably/perhaps present in all types of gas-rich galaxies and carrying the bulk of the dust luminosity (seen by ISO): http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2005SSRv..119..313S&db_key=AST&data_type=HTML&format=&high=4534ff5d9f10590 These old stars (red giants) are large dust producers, so I would say that Andromeda makes even more sense!
