About the only things that are unique to Earth are our biota and our culture. If aliens ever come here, they'd most… — Seth Shostak Copy Share Image
Buying insurance is no one's idea of fun. And it's especially easy to berate something as funky-sounding as writing checks to defend… — Seth Shostak Copy Share Image
Our computers double in capability on time scales of only a few years. It's hardly outrageous to believe that we will successfully… — Seth Shostak Copy Share Image
A century ago, scientists believed there was only one obvious stomping ground for alien biology in our solar system: Mars. Because it… — Seth Shostak Copy Share Image
It's hardly a secret that I'm skeptical of declarations that the aliens are out and about on our planet. Still, I try… — Seth Shostak Copy Share Image
Mining asteroids is a well-oiled trope of science-fiction. But someday, actually doing it will make economic sense. Many of the essential metals… — Seth Shostak Copy Share Image
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in… — Seth Shostak Copy Share Image
Just knowing that there's somebody else out there - that what's happened on this planet has also happened in many other places… — Seth Shostak Copy Share Image
When it comes to brains, size matters. It's not all that matters, of course. Whales and dolphins have brains that are larger… — Seth Shostak Copy Share Image
Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be… — Seth Shostak Copy Share Image
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon,… — Seth Shostak Copy Share Image
It's worth noting that invoking God as the entity who set our universe in motion isn't contradicted by the data. Of course,… — Seth Shostak Copy Share Image
Our retinas and brains have been wired by a hundred million years of evolution to find outlines in a visually complex landscape.… — Seth Shostak Copy Share Image
Thanks to the fact that the Earth isn't a perfect sphere, and invoking a bunch of Newtonian physics, you can deduce that… — Seth Shostak Copy Share Image
The limitless content of our universe might be only one instance of a large (and possibly infinite) number of other universes. — Seth Shostak Copy Share Image
Mountains aren't eternal: even the most imposing massifs are smoothed away by weathering in a few hundred million years or less. Plate… — Seth Shostak Copy Share Image
Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there… — Seth Shostak Copy Share Image
One of the jovian moons, Europa, is coated with twice as much liquid water as is sloshing around our planet. — Seth Shostak Copy Share Image
Exploration is an oft-lauded human activity, and one that resonates in the same way that music and good stories do. It's hard-wired… — Seth Shostak Copy Share Image
The mission of NASA's Kepler telescope is to lift the scales from our eyes and reveal to us just how typical our… — Seth Shostak Copy Share Image
Despite tantalizing suggestions of fossilized microbes in meteorites, puzzling and possibly biogenic methane gas in the martian atmosphere, and a long-standing controversy… — Seth Shostak Copy Share Image
Every day, the temperature of Sol's surface increases by five billionths of a degree, a change of no consequence for thousands of… — Seth Shostak Copy Share Image
'Dating Game' wasn't social commentary, political analysis, Shakespearean-level drama or even blunt-force comedy. It was just the televised equivalent of meeting someone… — Seth Shostak Copy Share Image

Some pundits have proposed that the aliens have come here to breed with us. Apparently, too much bike riding or something similar has rendered… — Seth Shostak Copy Share Image
As far as I can tell, the only unambiguous consequence of the claimed invasion of Earth by beings from another star system has been… — Seth Shostak Copy Share Image
Look, science is hard, it has a reputation of being hard, and the facts are, it is hard, and that's the result of 400… — Seth Shostak Copy Share Image
Give consideration to the fact that alien astronomers could have scrutinized Earth for more than 4 billion years without detecting any radio signals, despite… — Seth Shostak Copy Share Image
In a movie, it's often important to have aliens whose gestures and facial expressions can be 'read' by humans. And in the days before… — Seth Shostak Copy Share Image
Sure, nobody will make a fortune if we figure out why the Big Bang happened. But just about everyone would like to know. — Seth Shostak Copy Share Image
If you could drive straight down, into a tunnel bored through the crust of the planet, you'd hit this molten mess in about an… — Seth Shostak Copy Share Image
While I have always thought that the motivation for looking for E.T. was both self-evident and patently worthy, it's possible that I'm a victim… — Seth Shostak Copy Share Image
I studied Latin in high school, and I was reading stuff from Cicero. And that signal took a few thousand years to get to… — Seth Shostak Copy Share Image
About the only things that are unique to Earth are our biota and our culture. If aliens ever come here, they'd most likely be… — Seth Shostak Copy Share Image
This plucky NASA telescope is able to find planets en masse. If you compare planet hunting to prospecting for gold, then Kepler is equivalent… — Seth Shostak Copy Share Image
