Astronomers have observed the elusive ‘Phoenicid meteor shower’ and have determined that it was spawned by the now vanished Comet Blanpain. They also found that Comet Blanpain was active, though only weakly, in the early 20th Century. This is the first time that researchers could determine the activity of a comet by observing its associated meteor shower. These results are important for understanding the evolution of minor bodies in the Solar System.
