Feature Guest: Brian Fields
By now we are all familiar with the theory that an asteroid brought to an end the age of the dinosaurs, a period of domination that had lasted 167 million years. But asteroids are not the only harbingers of doom that lurk in the darkness of space. Today we’re joined here at The Star Spot by Brian Fields, whose research team has found evidence linking supernovae events in deep space to mass extinction events in deep time.
Current in Space
Tony reports on the mystery of the vanished star. Then Jeff describes electromagnetic flare from a gravitational wave event caused by two merging black holes. And Camilla brings news of two new super-Earths. Finally Amelia and Priyanka offer an explanation for radio waves caused by pulsars.
