The 50th anniversary of iconic rock magazine Rolling Stone arrived in November, and the party was long and loud. Origin stories have festooned the magazine and its website; a coffee table book appeared in May; Joe Hagan’s biography of cofounder Jann Wenner, Sticky Fingers, was published in October; and an HBO documentary is scheduled for November. To keep things interesting, Wenner announced that he plans to sell his company’s stake in the magazine, prompting a round of retrospective articles in The New York Times and elsewhere.
IN 2015, an observatory high in the Atacama Desert of Chile detected three planets orbiting an M star, an ultra-cool dwarf, in the constellation Aquarius about 40 light years, or 232 trillion miles, from Earth. Until then, the dim star was designated 2MASS J23062928-0502285. Not such a charming name. The discoverers of its satellites, a team of astronomers who operate the Chilean observatory remotely from Liege in Belgium, took the opportunity to warm up that appellation.
