The darkest time of the year is the winter solstice, the day with the least sunlight and the longest night. However, the coldest time of the year is typically about one month after the winter solstice. So why isn't the darkest time of the year also the coldest?

Jason Steffen is associate professor of physics at the ��ҳ| �鶹��ýӳ��. A longtime science team member of NASA's Kepler mission, he has contributed to the discovery and characterization of thousands of exoplanets that orbit distant stars. In the first half, he shared insights into the journey of the Kepler mission and its groundbreaking discoveries. Launched in 2009, Kepler operated for about four years and then was repurposed in what was known as the K2 mission, providing an additional five years of data. He explained the distinctions between Kepler and the Hubble Space Telescope-- Kepler was designed to be very precise at making measurements of stars, which allowed it to identify over 2,700 new planets, while Hubble was more adept at taking stunning photos.

Major change in airports. Efficient passenger boarding is an ongoing challenge for airlines and is essential to reduce delays and optimize the flight experience. In Romania, where air transport has become more and more accessible, the implementation of new rules could significantly improve this process. Following successful international strategies and adapting them to local airports could have a positive impact on passengers and airlines alike.

Although you may not believe it, boarding passengers on a plane is one of the most difficult operational processes of airlines. It may seem simple and predictable to passengers, but " boarding " is a complex stage with rigorous logistics behind it, designed to reduce the time spent on the ground and ensure maximum efficiency. Romania, through its major airports, Otopeni, Cluj-Napoca and Iași, could implement on a large scale internationally tested methods to improve this stage and reduce unnecessary waiting and flight delays, thus gaining customer respect and higher competitiveness in the regional market.

Jason discusses in new book "Hidden In The Heavens."

Dr. Jason Steffen, Associate Professor of Physics at the ��ҳ| �鶹��ýӳ��, 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.
