Dr. Jason Steffen, Associate Professor of Physics at the University of Nevada, Las Vegas, joins Lisa to talk about the new boarding method that United Airlines rolled out last month. While United claims their new boarding method will ease frustrations, Dr. Steffen says he has an even more efficient way. Dr. Steffan also previews his new book: “Hidden in the Heavens”

Travelers have spent years proving that the honor system doesn't allow for an orderly boarding process on airplanes, so now American Airlines is testing a way to make sure people actually board with their assigned group.

Although it’s hard to spot without a decent telescope, the mini moon is here through Nov. 25. The only similarity between the mini moon and Earth’s moon is they are both made of rocks, said Jason Steffen, an astrophysicist at 51�ԹϺ���.

It’s an important week for Southwest Airlines, as the carrier prepares to announce more details about its move away from the open seating model that’s long been its trademark. That's a major change for the Dallas-based carrier — one that Southwest has been considering since at least 2006.

You’d be forgiven for thinking you need an advanced degree to understand airplane boarding. In fact, even scientists have tried to crack the mystery of why boarding a plane can take so long. As airlines experiment with different methods, carriers have introduced processes so complex that they include as many as 10 different boarding groups — and even those in “Group 1” might find themselves boarding behind others. If you’re curious about this often-dreaded part of the air travel experience, take a closer look at how airlines determine how to board a plane.

Earth has one of the most interesting weather systems. Its atmosphere is ideal for moving hot and cold air around, and a hydrological cycle allows for precipitation. But throughout our solar system, there are other planets that have more extreme and also fascinating weather patterns worth exploring.

We’re interested in the moon because it’s close enough to Earth to allow us to practice setting up a base camp in preparation for Mars. In fact, Artemis III will send the first crewed spacecraft to the moon’s South Pole to set up camp by 2034.
