Ethan was born in New York City as the son of a Jewish postal worker. He did his undergrad at Northwestern, taught public school in Houston, Texas and Los Angeles, California, before moving to Florida, where he got his PhD in theoretical astrophysics at the University of Florida. After that, he moved to Madison, Wisconsin, where he taught at the University of Wisconsin, ate too much cheese, and also met his life partner, Jamie. After working in astrophysics research at the University of Arizona and starting the world-renowned science blog, Starts With A Bang, he moved from the hellish desert to rain-soaked Portland in 2008. Since then, he's been a professor at the University of Portland and Lewis & Clark College, grown a nationally renowned beard and mustache, got invited to join a circus and probably drank more beer than a healthy person should. He currently works as the head curator at Trapit, and can't wait to tell you a little bit more about the Universe.

“A hungry man can’t see right or wrong. He just sees food.” -Pearl S. Buck But what of a hungry galaxy?

“I created this project for fun. Initially, I had no business goals with it. I created this project recently. I was and still am a teenager myself, that is why I had a certain feeling of what other teenagers would want to see on the Internet. I myself enjoyed talking to friends with Skype using…

“I took a deep breath and listened to the old brag of my heart. I am, I am, I am.” -Sylvia Plath It’s been two weeks since our last edition of our Comments of the Week, and from the heartbreaking to the mystifying, there’s a lot we’ve written about and explored together. If you missed…

“From earliest times, humans — explorers and thinkers — have wanted to figure out the shape of their world. Forever, the way we’ve done that is through storytelling. It is difficult to let the truth get in the way of a good story.” -Adam Savage When we look back into the Universe, there’s a wonderful, remarkable story that it…

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” -Carl Sagan That might be true: all the heavy elements — in theory — were created after at least one generation…

The Physics of the Death Star (Synopsis)

“What’s that star? It’s the Death Star. What does it do? It does Death. It does Death, buddy. Get out of my way!” -Eddie Izzard It’s said — at least by Darth Vader — that the power to destroy a planet is nothing compared to the power of the force. But how much energy is that,…

“I told my father that someday when I grow up and become an astronomer ‘I’m going to discover something.’” -Thomas Bopp But who ever would have imagined that a kid with an armchair interest in astronomy, one who as an adult didn’t even own a telescope, would stare into a friend’s one fateful night at…

Everything is different now (Synopsis)

“Dogs are our link to paradise. They don’t know evil or jealousy or discontent. To sit with a dog on a hillside on a glorious afternoon is to be back in Eden, where doing nothing was not boring—it was peace.” -Milan Kundera Many of you have been along on this journey with me for years…

Throwback Thursday: The Green Flash (Synopsis)

“It does no harm to the romance of the sunset to know a little bit about it.” -Carl Sagan Although I often hear people utter sentiments that knowledge somehow undermines the beauty of the natural world — quoting some farcical poem about bad teachers like When I Heard The Learn’d Astronomer — I never quite understood it. How…

“I was confided to your loyalty and accepted by your treason; you offer my death to those to whom you had promised my life. Do you know who it is you are destroying here? It is yourself.” -Victor Hugo So those of you who’ve been paying attention may have just heard that we’ve mapped out…
