...number of other teams in what is starting to look like OSETI mania. At Princeton, physicist David T. Wilkinson will soon begin surveying nearby stars with a detector similar to Horowitz's. At the University of California, Berkeley, extrasolar-planet hunter Geoff Marcy is re-examining his data for sharp spectral lines that might indicate a continuous beam of light intended as a low-power signal. Another Berkeley team, led by SETI veteran Dan Werthimer, is looking for short, powerful laser bursts in a series of automated observations of 2,500 nearby stars. Later he plans to turn to invisible...
...College, uses the question of whether there is intelligent life elsewhere in the universe as a frame for the discussion of a selection of these discoveries. He presents, in a clear and easily accessible narrative format, topics ranging from organic chemistry to chaos theory to the recent discovery of extrasolar planets...
...giant: a big, gaseous sphere more than twice as massive as Jupiter and some 450 light-years from Earth. Susan Terebey, an astronomer at the Extrasolar Research Corp. in Pasadena, Calif., discovered it quite by accident while studying a cloud of gas in the constellation Taurus where a lot of stars are being born. When Terebey and her colleagues looked closely at one double-star system, they noticed a long wisp of gas trailing off into space, and at the end of the wisp, a tiny dot of light...
More surprises are almost certain to follow if astronomers find more and more planets circling other stars. But while finding new planets of any sort is terrifically exciting, says Alan Boss, an astronomer at the Carnegie Institution of Washington, "the Holy Grail is to find an extrasolar planet that is capable of supporting life...
