Lightning generally goes cloud to cloud or cloud to ground, but sometimes it shoots up to the ionosphere at the edge of space. We take a close look at strange lightning with lightning trivia. A baby star system in our own galaxy appears to be making a giant planet that’s less than two million years old, while the ages of distant galaxies observed by JWST are now a controversy. Catch up with us on all the latest and greatest space news and discoveries.
If you're tired of flipping coins and rolling dice, and ready to move on from prior probability to posterior probability, try Bayesian statistics. Allowing knowledge to inform your statistical arguments, Bayesian statistics lets you to solve the Monty Hall problem and win a car. Take advantage of new information and leave your frequentist and classical probability interpretations behind and tackle problems from the multi-armed bandit to the shapes of celestial bodies based on limited occultation data. With Bayesian statistics, you may not get a car, but you're more likely to know if you will or not. Bayesian statistics, luck has nothing to do with the games they play (Casino, 1989).
