That story was posted on April 1st in 2009, and isn't hosted on BBC's website. There isn't even a first name given for the researcher (only "Radio astronomer Dr. Venn"). Looks sketchy to me.

I can't find any other information about it, so I'm guessing its a hoax / April Fools joke.

I was actually wondering that too but couldn't find anything definitive saying its a hoax.

I have to think it would have been a huge deal if it were real, no?
