Early Monday morning, a fireball lit up the night sky over Wisconsin. For a just a second, dark became light. And then there was an explosion followed by a terrifying sonic boom. Loretta Brockmeier, a resident of Random Lake, Wisconsin, a town about 40 minutes north of Milwaukee, got up to use the bathroom and […]
Winter Solstice passed last week. I think of how far the Northern Hemisphere has pitched us into space this time of year, tipping us away from the sun’s light. This is when middle latitudes in the north get 9 hours and 30 minutes of daylight out of a 24 hour day. The North Pole sees […]

The past few days have been a cosmic convergence of opinions about extraterrestrial life. First, I’ve been interviewing scientists and engineers who think that funding searches for planets that might support life isn’t unreasonable. Second, a neighbor told me he’d read in the New York Times that extraterrestrial life almost certainly had evolved somewhere, some […]
