Feature Guest: Alan Stern

There’s an intruder in our solar system. This fall we were invaded by the first interstellar space traveller, an elongated, cigar shaped alien asteroid. The mysterious object was ejected from its distant and unknown home, travelling for millions or billions of years before coming to pass between the Earth and the sun. On today’s episode of The Star Spot we’re joined by Dr. Alan Stern, principal investigator for the New Horizons mission to Pluto, to explain how the detection of an interstellar asteroid named Oumuamua is likely the first of many such strange and bizarre objects, and heralds the dawn of a new era in astronomy.
