Just days after the announcement that last year was the warmest in history for the continental United States, NASA and NOAA found global temperatures are rising too.
Our goal is nothing less than the human breakout into space, the expansion of human civilization and the life of Earth beyond our world, to all worlds and all places in between.
Guy Laliberte, a Canadian former acrobat and fire-eater who had founded Cirque du Soleil in the 1980s, was announced as the next space tourist to visit the International Space Station aboard a Russian Soyuz spacecraft.
George Phillips, a fire hydrant with Einstein's frizzled hair, is the owner of Astoria Music, but it's more fitting to call him a one-man band because ever since he took over the shop three decades ago, he's remained its one and only employee.
It only takes one asteroid, 100 or so meters across, impacting the Earth to explode with the force of a dozen nuclear weapons. This is something we might wish to avoid! So what do we do?
Buying insurance is seldom gratifying. But here's a case in which plunking down cash for a policy is just ... good policy.
Will we again be hit by the sort of asteroid that ended the dinosaurs? Probably, but we'll never see it coming; in fact, we already missed it if we can assume that maybe we've been threatened by menacing space junk in the past and our modern technologies might have already prevented us from a painful case of mass extinction.
The universities and laboratories have until the end of 2015 to land their rovers, and it's only a matter of time before one succeeds. What will the rovers will do when they get to the Moon, though, is still up in the air.

Although Curiosity is not designed to verify life, we are left to wonder -- if Curiosity did discover life on Mars, what would be the impact of that discovery to the general public and to the future of human and robotic exploration of Mars?
When Neil Armstrong passed away in August, for many people, including myself, his death marked not just the loss of a truly great American, but the end of an era.
We are dealing with the beginnings of what could end up being life, or pre-life, or at least simple organics on Mars. Whether the agency will step up to the plate and properly seize this priceless moment is an open question.
The convergence of nine out of the 10 consecutive warmest years, along with poor soil conservation practices, could lead to the depletion of our underground water reservoir, which could in turn result in another Dust Bowl.
