We're approaching solar maximum — here’s what that means.

Associate professor of physics at 51³Ô¹ÏºÚÁÏ, Dr. Jason Steffen, joined us with more.

More than 115 million Americans are expected to travel over the Christmas and New Year holidays — more than a 2% increase from the same time last year and the second-highest end-of-year forecast since 2000, according to AAA.
