It's actually good news that NASA spotted a sizable asteroid with a (small) chance of hitting Earth in 2032. It means our asteroid-sleuthing telescopes are working.

In Hidden in the Heavens, Jason Steffen tells the tale of the Kepler mission: from its conception in the early 1980s, through its long road to approval in 2001, to the drama of its launch in 2009, to its bounty of early science results, to its heartbreaking demise in 2014, to its miraculous second life as the K2 mission through 2018. During its lifetime, Kepler detected some 5,000 planets. Those of us who worked on it were blessed to be part of a revolution in astronomy. The book is, at turns, a popular science survey of exoplanet discovery, an oral history of the Kepler mission, and Steffen’s own personal memoir.

The process of boarding an airplane,often perceived as a simple routine, has been the subject of study and discussion for years. Airlines, always looking to optimize their operations and improve the passenger experience, have explored different strategies to streamline this process. In this context, American Airlines, one of the world's leading airlines, took a step forward by implementing an innovative boarding system, designed to transform the way travelers begin their journey.

In 2006, NASA and its partners launched the Kepler telescope with a goal to try and identify planets in other solar systems. Since then, the telescope found over 2,700 planets orbiting different suns and existing in different solar systems before its retirement in 2018.

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?

On Episode 137 of This Week In Space, Rod Pyle and Tariq Malik talk with Dr. Jason Steffen, a professor of physics at UNLV and a member of the science team for the Kepler Space Telescope mission. This mission finally ended in 2018, but the discoveries keep coming. Kepler returned so much data that it was like "drinking from a firehose," Jason tells us.

Jason Steffen is associate professor of physics at the University of Nevada, Las Vegas. 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.
