WMAP cold spot: a huge hole
Click for an article.
In the right lower "corner" of the WMAP pictures, there is a rather small and thin blue region - the so-called WMAP cold spot in the constellation Eridanus. Some people argued that they could see non-gaussianities there at 3 sigma. At any rate, the Very Large Array radio telescope has looked into this region and concluded that there are virtually no stars in that direction and at distance between 6 and 10 billion light years: there is a gargantuan hole there. They also call it "Woit" because "void" means emptiness, vacuity, lacking legal validity: every void is transparent and has no content.
The hole is so huge that it looks like Mother Teresa's spiritual hole: it turns out that she has been a cryptoatheist for 50 years.
