New measurements claim to resolve the controversy over the distance to the Pleiades but have in fact only reignited the debate. See reports at Nature and Science.

It boils down to a competition between a couple of parallax measurements. One on the Earth and another by a satellite. Both by methods highly reliable in every other instance. Thus it is quite intreguing.
It's interesting enough that parralax measurements are down to 1.5% uncertainty.
The gripping hand is that there's another satellite coming.
