Exomoons Can Spoof Exoplanet Biosignatures
Astronomers hope that one day soon we’ll obtain a spectrum of light that might tell us whether or not an Earth-sized exoplanet harbors life.

Heads Up! Thirteen Years Of Asteroid Impacts On Earth
Since the Chelyabinsk event in early 2013, when a brilliant meteor fireball streaked across Russian skies and exploded with the energy of thirty Hiroshima bombs, humans have paid slightly more attention to the potential danger of asteroids than before.
Copernicus in Cleveland
What is our cosmic significance? Does it even make sense to ask a question like that? If you happen to find yourself in Cleveland, Ohio this coming Thursday evening, and stop by the Cleveland Museum of Natural History at 8pm you can catch me talking about this.
What do NYC Streets and Asteroids Have in Common?
Fatigue, that’s what. As a particularly frigid winter recedes across the north and east of the United States (we’ve become accustomed to milder weather in past years), the abuse suffered by asphalt roads is becoming apparent.
The Unstoppable Extinction And Fermi’s Paradox
There has been a lot of discussion recently about the evidence that we are currently within a period of mass extinction, the kind of event that will show up in the fossil record a few million years from now as a clear discontinuity, a radical change in the diversity of life on the planet.
This Is What We Don’t Know About The Universe
In recent days I’ve had some interesting conversations. There’s a giddiness going around, related to an outpouring of science love – the kind you get from President Obama introducing TV science shows, the kind that has wonderful visuals, but is, well, a wee bit simplistic (a sin that none of us could ever, ever be [...]
Rock-Eating Martian Microbes?
A recently published study of a 30-pound martian meteorite found in Antarctica suggests the presence of indigenous carbon-rich material, ancient water erosion, and a number of tiny structures that resemble the sort of features that we see rock-eating microbes leaving in basaltic glasses here on Earth.
So You Want To Be An Exozookeeper?
This week has seen the release of the latest set of ‘confirmed’ exoplanets from NASA’s Kepler mission.
Your Friendly Neighborhood Asteroid Swarm
The solar system is full of bits and pieces, remnants of its heyday of activity 4.5 billion years ago. Planets are the most noticeable fossil leftovers, with giant Jupiter being two and a half times more massive that the sum total of the other major worlds.
Mystery of Mars ‘Doughnut’ Rock Solved
About a month ago an intriguing pair of images from NASA’s Opportunity rover on Mars showed a curious rock that had seemingly appeared our of nowhere during the course of 12 days.
