Things You Didn't Know About ... Aliens


1 Astronomers Margaret Turnbull and Jill Tarter of the Carnegie Institution in Washington, D.C., have compiled a list of 17,129 nearby stars most likely to have planets that could support complex life.

2 According to Turnbull, stars must be at least 3 billion years old (to allow life time to evolve), have low mass, and have high levels of iron; metals are needed to form rocky, Earth like planets.


3 Leading the list is Epsilon Indi A, a dim orange star just 11.8 light-years away, in our local corner of the Milky Way.

6 The more sophisticated efforts of the SETI Institute in Mountain View, California, haven't fared any better. Since 1995, this privately funded project has scanned more than 1,000 stars, at a cost of $5 million a year, for alien radio squeaks.

7 Seth Shostak, senior astronomer at SETI, for reasons best known to him, reckons that the 350-antenna Allen Telescope Array, now being built, "will trip across a signal by the year 2025."

10 Perhaps the earliest UFO sighting occurred in 1450 B.C., when Egyptians saw bright circles of light in the sky. Some UFO obsessives interpret Ezekiel: 1 in the Bible as a UFO report.
