No, it doesn't eliminate the use of Cepheids, but it vastly complicates matters. The distance scale needs to be adjusted, not thrown out. -- Joe --- On Sat, 1/15/11, erikhansen@thebluezone.net <erikhansen@thebluezone.net> wrote:

I do hope you all read the link Patrick provided to the NASA release on Cepheids in his newsletter. Thanks to Patrick for his continued e-mailing of news.
It does seem, it is just saying to examine the data more carefully and that the distance data provided by Cepheids is still a good ballpark figure. I does not eliminate them from distance measurements.
Hi,
Great article on Cepheid Variables. Your explanation is clear and understandable for the masses. Keep up Your great blog.
