More Evidence for a Preferred Direction in Spacetime - Technology Review: They point to evidence from the study of Type 1 supernovas, which appear to be accelerating away from us, indicating the Universe is not just expanding but accelerating away from us. The curious thing is that this acceleration is not uniform in all directions. Instead, the universe seems to be expanding faster in some directions than others...
Today, they confirm that the preferred axis is real. According to their calculations, the direction of greatest acceleration is in the constellation of Vulpecula in the Northern hemisphere. That's consistent with other analyses and also with other evidence such as other data showing a preferred axis in the cosmic microwave background.
