astroengine writes "In research accepted for publication in the Astrophysical Journal, astronomers documented the anomalous spin rate of a pulsar that has been observed 'multiple times' between 1988 and 2012. In September 2005, the spin rate of the well-observed PSR J0738-4042 changed and a team of astronomers headed by Paul Brook, of the University of Oxford, think they know why. 'The data lead us to postulate that we are witnessing an encounter with an asteroid or in-falling debris from a disk,' they write in a paper published to the arXiv pre-print service. The moral of the story? It's not just black holes that get the asteroid munchies."
