The computers at the StarDate office have been scanning for ET lately overnight, on weekends, whenever one of us is away from his desk. Of course, if we had detected a message, you would have heard about it before now. We'll keep searching, though, along with hundreds of thousands of other computer users worldwide who've downloaded software that looks for intelligent radio signals from space. Find out how SETI@home has taken the world by storm.
The Mars Channel
This summer marks the 75th anniversary of another worldwide effort to listen for signals from another world. The medium in 1924 was America's fledging AM radio network, rather than the Internet of today, but the target was a familiar neighbor. Tune in to "The Mars Channel" on page 16.
Sun Up
Another familiar neighbor is returning to his old ways. The Sun is headed for another peak in its ageless cycle of calm and chaos. Will scientists' theories and predictions for sunspot activity hold up? Will our fragile electronic systems and power grids withstand a constant barrage of solar bursts? Frequent StarDate contributor Bob Zimmerman tells us what to expect starting on page 4.
