An odd dense spot in the universe populated by a surprising amount of matter has been puzzling scientists since it was revealed in March in an all-sky map made by the European Planck satellite. This feature and other mysteries in the observations may point the way toward new theories of physics, say scientists who met recently to discuss the implications of the findings.
Three Planck team members will answer public questions about the Planck data during a Google+ Hangout on Wednesday (July 31) at 3 p.m. EDT (1900 GMT), sponsored by the Kavli Foundation. You can watch the Hangout live here on SPACE.com. Questions for the researchers can be submitted in advance by emailing email@example.com or posting on Twitter with hashtag #KavliAstro.
