Here is the original thread. http://setiathome.berkeley.edu/forum_thread.php?id=74330

The BICEP2 telescope studied a small patch of sky in detail above the South Pole

Scientists who claimed last year to have found a pattern in the sky left by the super-rapid expansion of space just fractions of a second after the Big Bang were mistaken.

The signal had been confounded by light emission from dust in our own galaxy.

This is the conclusion of a new study involving the US-led BICEP2 team itself.

A paper describing the findings has been submitted to the peer-reviewed journal Physical Review Letters.

A summary was briefly posted on an official French website on Friday before being pulled. A press release was then issued later in the day, although the paper itself is still not in the public domain at the time of writing.

A determination that BICEP2 was mistaken in its observations is not a major surprise.

AFAIK the Bicep2 scientists had taken their data on dust from a slide shown in a presentation of the Planck results by the Planck team. This was very wrong, you cannot use unpublished data.
