Perkil8r Posted May 24, 2013 Share Posted May 24, 2013 http://scitechdaily.com/new-distance-measurement-of-ss-cygni-resolves-major-astronomical-mystery/ Using VLBA and the European VLBI Network, astronomers were able to accurately measure the distance to double-star system SS Cygni, resolving a major problem in the understanding of a class of stars that undergo regular outbursts. This makes me wonder how many other measurements have previously been so far wrong? 370 is a lot closer than 520light years, the discrepancy is greater than 33% Link to comment Share on other sites More sharing options...

+Graham Posted May 24, 2013 Share Posted May 24, 2013 (edited) That is quite a difference! Not really Tobias. Remember in the olden times they used cloth tape measures and they did tend to stretch a bit especially if they got wet. Unlike the metal ones of today.

xanthic Posted May 24, 2013 Share Posted May 24, 2013 I'm surprised they've never put a pair of satellites up to do this. Good work though. Link to comment Share on other sites More sharing options...
