How do you make astrometry fun? Well, you don’t, of course. Astrometry is the precise measurement of the position and motion of astronomical objects. It is not something one takes lightly. It requires skill, exactitude, and lots and lots of math. Nevertheless, the good folks at Astrometry.net are working...

It’s the year 2030, and humans are finally undertaking interplanetary travel with a historic mission to the Red Planet. This is the premise for Discovery Channel Canada’s 4-hour “Race to Mars” mini-series, which the network describes as its most ambitious project to date. (Watch the trailer .) The show...

A 2004 New York Times article about medieval Arabic manuscripts triggered the question. The city of Timbuktu, Mali, was one of Africa’s intellectual...

Looking for a different sort of vacation? Consider a trip to Mars. The European Space Agency (ESA) wants you. The mission, slated to begin next summer, is to work and live in a simulated spaceship for a 520-day round-trip to the Red Planet. Aside from weightlessness and radiation, the simulation will...

In 1959, British scientist and novelist C. P. Snow suggested that what slowed progress in solving the world's problems was a communications breakdown: scientists and artists no longer talked to one another. The title of his University of Cambridge Rede Lecture, " The Two Cultures ," has...

NASA Former astronaut Wally Schirra died May 3 at the age of 84. He was one of NASA's "Original Seven," the first crop of astronauts selected in April 1959, and the fifth man in space. Schirra was the only astronaut to fly in all three of the U.S. space agency's pre-shuttle programs...

With its exciting operations at asteroid Itokawa in late 2005, Japan's Hayabusa showed the time has come for on-site exploration of near-Earth asteroids and comets. Dennis Ebbets and his colleagues at Ball Aerospace and Technologies Corp. in Boulder, Colorado, presented a novel design concept for...
