This Wednesday, we're telling you about the most powerful solar storm to strike the Earth in more than 20 years -- and explaining why you might not have even noticed. It's followed by a report on why a widespread health condition worsens in cold weather. And our history topics center on a controversial action by a former president and a historic trip by a former pope. Plus: the world's coldest marathon, the European prisoners finding purpose in making cheese, and the police officer who had to arrest chickens.
