Chandra and the Hubble constant

The Chandra X-ray Observatory has released a new estimate of the Hubble constant - very important for working out lots of things about the universe - using measurements of the Sunyaev Zel'dovitch effect. It is quite late at night here so I won't write a full entry on this one. Instead you can read the articles by Phil, Tom, Fraser Cain or the original press release. The peer-reviewed article should be in Astrophysical Journal today (August 10th).
