These were announced here six weeks ago. There has been sufficiently good progress made to warrant another announceme ..

Ive known for a long time that Betelgeuse is prob ..

This is clearly proven by the orbits of stars very close to the galactic center( see for instance http://www.mpe.mpg.de/wwwir/GC/ ..

I believe Herschel will instigate one of t .. Fri, 29 May 2009 04:53:33 -0400
