The central region of the Milky Way, known as the bulge, is stuffed with literally tens of billions of stars. And most of these are old - considerably older than our Sun or its neighbors - because this part of the galaxy formed first. Consequently, b...
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 our neighborhoods against apartment-size rocks from space. But this is one insurance pitch that makes perfect sense. ...
The usual metric for whether a planet is habitable or not is to ascertain whether liquid water could exist on its surface. Most worlds will either be too cold, too hot or of a type (like Jupiter) that may have no solid surface and be swaddled in noxi...
'Battleship' is not a film that Francois Truffaut would have made. Nor would any of those other namby-pamby European directors. Nope, this picture eschews that Continental obsession with small stories, set in quaint towns filled with pockmarked folk ...
In days gone by, scientists would speak solemnly about our solar system's 'habitable zone' - a theoretical region extending from Venus to Mars, but perhaps not encompassing either, where a planet would be the right temperature to have liquid water on...
We've accounted for 95 percent of all the stars in the Milky Way. The other 5 percent are big, bright stars - the kind that dominate the night sky, but are lamentably both rare and short-lived. If biology's your thing, you can forget those guys.
What's a space elevator? Simply described, it's a thin ribbon, about 3 feet wide and 60 thousand miles long, stretching upwards from the surface of the Earth. The lower end is bolted to a heavy anchor (think of an oil drilling platform), and the top ...
Consider that the overwhelming majority of those 40,000 near-Earth asteroids are small enough to fit on the parking lot at the mall. And while these rocky runts won't cause Armageddon, they could still flatten such popular hominid hangouts as Manhatt...
Explorers tend to be the aggressive types - why else would they risk scurvy, mutiny and other bad things to go out there? So, you could say that any aliens that are actually moving and interested in going somewhere are likely to be more aggressive. B...
Religion is an insult to human dignity. With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion

Any enterprise CEO really ought to be able to ask a question that involves connecting data across the organization, be able to run a company effectively, and especially to be able to respond to unexpected events. Most organizations are missing this a...
The world's urban poor and the illiterate are going to be increasingly disadvantaged and are in danger of being left behind. The web has added a new dimension to the gap between the first world and the developing world. We have to start talking about...
When you talk about evangelicals, don't forget that a significant proportion of the evangelical community is African American. And most African Americans - well over 90 percent, thoroughly evangelical, thoroughly biblical - will probably vote Democra...
What we need to affirm is that Jesus is neither a Democrat nor a Republican. Whenever we marry Jesus to a political party, we are committing the sin of idolatry. We are making Jesus into the image of our political party.
That's what they do in Europe. You go down to the city hall and you become legally connected. You have a civil union there. Then, if you're religious, you go down to the church, and the church blesses the union. That gets the problem solved.
It appears a bold thing to say so when one sees how much many a modern author who knows how to make a skilful use of the Book of Chronicles has to tell about the tabernacle.
Give me one hundred preachers who fear nothing but sin, and desire nothing but God, and I care not a straw whether they be clergymen or laymen; such alone will shake the gates of hell and set up the kingdom of heaven on Earth.
Offendedness is just about the last shared moral currency in our country. And, I'm sorry, but it's really annoying. We don't discuss ideas or debate arguments, we try to figure out who is most offended.
Sometimes feeling overwhelmed is part of what it means to be a Christian. You can't bear somebody else's burden unless you are taking something of their load and it's weighing you down a little bit.
Just about the worst thing a leader can nurture in his heart is self-pity. And just about the worst thing a leader can do in front of his people is murmur and complain.
