Thanks Pete. That means the expansion age of the visible universe is less
than usually stated.....that brings problems with older stars...but not
much if only 73

For those of you that don't get Astronomy magazine, here's something from
their online site. Hopefully you can click through to the article. In case
you can't, here's a brief summary.
Hubble's widefield scope/camera have been used to more accurately refine
the Hubble Constant. It has been increased to 73.2 kilometers per second
per megaparsec. (A megaparsec equals 3.26 million light-years.) The new
value means the distance between cosmic objects will double in another 9.8
billion years. The error factor has been reduced to plus or minus 2.4%.
The problem is that measurements using the Cosmic Microwave background by
WMAP anf the Planck telescope show a rate 5 to 9 percent lower.
