If biologically important organic molecules like amino acids could form in interstellar space, the implications would be enormous. On the Earth we find plenty of amino acid species inside certain types of meteorites, so at a minimum these compounds can form during the assembly of a proto-stellar, proto-planetary system (at least this one) and end [...]..
The skies of Mars just got a little more crowded. On September 21st, 2014 NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) fired its engines for some 33 minutes in order to swing into a safe orbit...
Ever feel that broadcast TV fails to tackle the big issues? I don’t mean the state of the economy, healthcare, the future of clean energy, or what B-list celebrities had for breakfast – I mean the Really Big Issues...
…living in a place that makes doing cosmology hard. Let’s backtrack a little. Unless you’ve been living under a particularly thick and insulating rock you’ll know that in recent months the world of experimental cosmology (what would have previously been called observational cosmology, or just plain old astronomy) has been on tenterhooks waiting to see [...]..
We’re used to thinking of the space between the stars as void, bereft of all but the most sparsely distributed atoms and molecules, or the occasional microscopic grain of silicon or carbon dust...
This post is one in a series covering, and expanding on, topics in the book The Copernicus Complex (Scientific American/FSG). The conversation usually goes like this: Do you think we’re alone in the universe?...
After a ten year journey, NASA’s New Horizons mission is still 420 million kilometers from the Pluto system – but that’s close enough to begin to see the orbital dance of an icy world and its major moon...
In a month’s time, the end result of two-and-a-half years of research, thinking, writing, re-writing, re-re-writing, editing, mulling, puzzling, coffee-drinking, beer-swilling, swearing, and tweaking will hit the shelves in the form of my new book The Copernicus Complex...
It's summer in the northern hemisphere of a small, damp, planet orbiting a middle-aged star in a spiral galaxy of matter enjoying a brief heyday before colliding with another galaxy in some 4 billion orbits of the same small, damp, planet...
