hmm. while we're parsing the press release for every last bit of info, i might as well point out a typo:
"galaxies" is plural. the possessive form of "galaxy" is "galaxy's"
unless, of course, there's more than galaxy whose fate hangs in the balance. which somehow i doubt.
You should watch out for typos when complaining about typos
Case in point: "... there's more than ONE galaxy..."
Also, it should be mentioned that the plural possessive form is galaxies', which isn't used, either.
