The Music Of Our Spheres

What does Space sound like? As an astronomer, I could tell you about interplanetary gas, magnetic fields and the physics of waves propagating through them both. But that's really not the answer that matters as we cross the 50-year threshold of an epoch-making walk on the Moon. This month marks an anniversary that asks us to reflect on the profound impact the Apollo mission left on human culture.

It was a telling moment: David Wallace-Wells, author of the new book The Uninhabitable Earth, was making an appearance on MSNBC's talk show Morning Joe. He took viewers through scientific projections for drowned cities, death by heat stroke and a massive, endless refugee crisis — due to climate change. As the interview closed, one of the show's hosts, Willie Geist, looked to Wallace-Wells and said, "Let's end on some hope."

So, it's Election Day here in the United States.

Every presidential election seems important, but I am sure that I am not alone in thinking this one is different, maybe more important than most.

So, please, go vote.

When you're done, I give you (once again) Carl Sagan's beautiful "Pale Blue Dot" speech to put it all in perspective.
