Comet Lulin

Here and Now’s space-watcher Kelly Beatty joins us to talk about a rare celestial event. Tonight is the night for Earthlings to get a good look at the comet called Lulin as it zips by our planet. Astronomers call Lulin an oddball because unlike most comets it circles the sun in clock-wise motion and from Earth appears to be chasing its own tail. Beatty will also tell us about the growing problem of space debris in Earth’s orbit and what space agency officials are planning to do about it.
