Goodman's best known work has come in the field of measuring magnetic fields in star formations, an interest she has pursued since writing her doctoral thesis at Harvard a decade ago on interstellar magnetic fields. She has taught at the University since then...
...stars typically pulsate comparatively slowly, Horowitz's device is calibrated to spot intense stellar flare-ups lasting only a few billionths of a second. Such "events," he figures, would probably be powerful bursts of artificial light aimed at us from an inhabited planet orbiting that star. In short, an interstellar hello...
Could aliens actually send a flash across our Milky Way galaxy? Without a doubt, says Nobel laureate Charles Townes, who first suggested lasers as a tool for interstellar communication nearly 40 years ago. Adds Werthimer: "They may have stuff out there we couldn't even dream of." O.K., E.T., never mind the phone call. Start blinking...
...plot moves forward as a sense of urgency is introduced: Martin must repair the spaceship soon or else the ship's Interstellar Safety System, designed to keep other races from acquiring the advanced Martian technology, will explode. Meanwhile, a government agency, SETI has been trying to find the Martian. Will Uncle Martin get off the planet before the greedy scientists get their hands...
...goes the theory, at least, and early studies of Hale-Bopp's gases bear this out. "We've found a type of hydrogen cyanide that's otherwise seen only in interstellar space," says Owen. "We saw it in Hyakutake too, but we thought it could be a fluke." Astronomers have found other gases they suspected would be there, including ammonia, methane, alcohol, formaldehyde and other organic compounds. Says Michael Mumma, an astronomer at NASA's Goddard Space Flight Center: "It's been suggested that both the building blocks of life and the water in our oceans fell to Earth...
