Join us today as we look at how fractures on Europa’s surface are leading scientists to reevaluate the geologic past of the Jovian moon. Speaking of Jovian moons, Sweden has finished an instrument for the JUICE mission that will measure electromagnetic fields and map the oceans of Ganymede. And finally, Comet NEOWISE continues to make headlines with new images from Hubble and Gemini.

First, we look at how researchers detected the afterglow of a short gamma ray burst a mere 3.8 billion years after the Big Bang. Then we examine the discoveries of a spiral structure in the disk of a young, heavy star and how red giant stars with large starspots spin faster than those without. And finally, we see how machine learning can be used to predict what planetary systems are most likely to survive.
