Astronomers Find Star That Has Exploded Six Times – ExtremeTech

Astronomers have spotted something that shouldn’t exist–a star that acts as if it’s gone supernova at least six times. Writing in Nature, an international research team discusses the highly unusual case of iPTF14hls, first classified as a Type II-P supernova on January 8, 2015. At first, this appears to have been an open-and-shut designation (II-P supernovas […]

Jupiter’s strange auroras are weirder than expected

In a study published in Nature Astronomy this week, astronomers announced that they’d finally been able to observe Jupiter’s southern x-ray hot spot in detail using data from the XMM-Newton and Chandra space observatories in 2007 and 2016. Surprisingly, Jupiter’s x-ray hot spots weren’t exactly in synch across the hemispheres. Source: Jupiter’s strange, pulsating auroras are even more mysterious […]

Newly discovered planet is nearly 25 percent the size of its star

How does a gas giant form near a dwarf star? What does it take to build a gas giant? Building models of planet formation and studying exosolar systems have both provided us with some hints. But there’s a small but growing list of cases where the two of these approaches disagree about what’s possible. A new […]
