And where lawyers go, venture capitalists and investment bankers are sure to follow.

it may not be well-known, but the planet Mars is actually the property of Adam Ismail, Abdullah al-Umari and Mustafa Khalil. The three, from the Middle Eastern nation of Yemen, claim to have inherited the planet from their ancestors some 3,000 years ago. “Sojourner and Pathfinder,” they recently charged in the Arabic weekly Al-Thawri, “which are owned by the United States government, landed on Mars and began exploring it without informing us or seeking our approval.” They’ve filed suit in San’a, Yemen’s largest city, demanding an immediate halt to all NASA activity on Mars until the court decides the case.

Their claim, of course, is a bit out there, but the issue they raise should not be laughed off.

Earlier this summer some of the world’s top space scientists gathered at Princeton University for the Space Studies Institute’s biannual conference. Since 1974, the Institute, which was founded by physicist Gerard O’Neill and is now headed by Freeman Dyson, has examined man’s expansion into space. Past SSI conferences have included discussions of orbiting space colonies, lunar bases and vast arrays of solar energy panels in orbit around Earth. This year, man’s ownership of space was the order of the day, and, as would be expected, a number of lawyers were on hand.

Rise of the Super-Earths

Astronomers have discovered a giant new kind of planet that could hold life -- and they could change everything

Topics:,
This article is an adapted excerpt from the upcoming book, "The Life of Super-Earths," available on January 23 from Basic Books.

We love our planet Earth. We should — it is our home, and there’s no place like home. There can’t ever be a better place than Earth. Plenty of serious science literature supports that view in an emotionally detached manner. It is often called the “Goldilocks hypothesis”: the Earth is just the right size (not too big, not too small) and just the right temperature (not too hot, not too cold) for life to emerge here. Life is a rare thing. Perched on our little planet, we can’t see any other out there, or at least not yet — so a certain dose of Earth-centrism seems justified. Or is it?

The science of warp

From time travel to interstellar communication, an expert explains what sci-fi gets right and wrong

time warp

Topics:,

“Back to the Future,” “A Christmas Carol,” the “Terminator” series, “Star Trek,” “Rip Van Winkle,” “Hot Tub Time Machine,” “Terra Nova” — the list goes on. We, as a culture, have been mesmerized by the idea of traveling in time: going back to fix life-changing mistakes we regret; going forward to get a sneak preview at what we’ll become. Equally transfixing is the notion of traveling through space, exploring galaxies and unknown universes far beyond our sight’s reach.

The Internet: Triumph of human evolution

The Web is more than just a powerful tool, it's our greatest adaptation. An expert explains why

Topics:,

The Internet allows us to do all kinds of things we never imagined possible. It lets us communicate with people across the world. We can learn whatever we want at the click of a button. We can navigate roads using our iPhones, and translate languages within seconds. It makes us smarter, and more versatile, and faster than ever. But the Web isn’t just a truly extraordinary invention, it is the apex of human evolution — and the ultimate evolutionary adaptation.

It may seem strange to think of the Web as part of the process of natural selection, but Raymond Neubauer, a professor at the University of Texas, doesn’t think so. In his far-reaching new book, “Evolution and the Emergent Self,” he argues that technology should be seen as part of our planet’s grand evolutionary narrative. He claims that two evolutionary strategies — one, emphasizing simplicity and rapid reproduction (as in bacteria), and the other, emphasizing complexity and hyper-intelligence (as in humans) — have been hugely successful in dominating the planet. The book charts the ways those strategies have managed to pop up everywhere from the animal kingdom to cellphones.

How to kill a coal plant

As a recent British protest shows, nonviolent civil disobedience may be our best hope to counteract global warming

How to kill a coal plant

In the early morning of Oct. 8, 2007, a small group of British Greenpeace activists slipped inside a hulking smokestack that towers more than 600 feet above a coal-fired power plant in Kent, England. While other activists cut electricity on the plant’s grounds, they prepared to climb the interior of the structure to its top, rappel down its outside, and paint in block letters a demand that Prime Minister Gordon Brown put an end to plants like the Kingsnorth facility, which releases nearly 20,000 tons of carbon dioxide into the atmosphere each day.

For a bit of change, let’s talk about a different kind of health care reform — the kind that affects the health of the planet.

The other evening, I was listening to “All Things Considered” on NPR. Robert Siegel was interviewing Dr. Hal Levison, a planetary scientist at the Southwest Research Institute in Boulder, Colo., about the king-size comet that slammed into Jupiter a few weeks ago.

The comet’s impact — it punched a hole the size of the Pacific Ocean, and would have annihilated a lesser planet, like Earth — was discovered by an amateur astronomer in Australia. Siegel asked how such an event escaped the notice of the world’s great observatories.
