Editor's note

Last year, for the first time since the industrial revolution, Britain went several days without any coal-powered electricity. Though coal and gas was used to generate three quarters of Britain’s electricity as recently as 2010, the country’s coal industry has since collapsed, largely replaced by wind and other renewables. It will be hard to maintain such rapid growth in renewable energy over the next decade, say Grant Wilson and Iain Staffell, but thus far Britain’s energy transition has been remarkable.

A cosmic explosion producing as much energy as the sun radiates in 1,700 years showed up on an astronomical alert system last summer. Nicknamed “The Cow”, the flare is one of the most mysterious and well-observed objects recently discovered in the sky. Paul M. Kuin explains how he and other researchers are solving the puzzle of what it actually is.

Meanwhile, our colleagues at The Conversation US have been busy covering the government shutdown. Negotiations expert Parker Ellen looks at how both Trump and the Democrats could end up claiming a win. And The Conversation Canada considers a fascinating experiment involving an astronaut and his identical (earth-bound) twin.
