Host Dave Schlom is joined by two scientists from the SETI Institute in Mt. View, California, to talk about one of his
favorite celestial phenomena -- comets.
Bright comets that are visible to the naked eye are truly a
spectacle as they hang in the sky like ethereal ghosts as they make their stately way around the Sun and
back out into the depths of the solar system.
SETI Institute research scientist Ariel Graykowski and Senior Planetary Astronomer Franck Marchis join Blue Dot to give us an extensive overview of what comets are, how they behave, and why they are so interesting to planetary astronomers and casual stargazers alike!
