In Cosmic Company, Seth Shostak and Alex Barnett ponder the possibility of aliens visiting the Earth, as well as the consequences of receiving a signal from the cosmos proving we're neither alone, nor the most intelligent life forms. They explain why scientists think life might exist on other worlds, and how we might contact it. Shostak and Barnett, experienced writers of popular astronomy, provide an accessible overveiw of the science and technology behind the search for life in the universe. Seth Shostak is a Senior Astronomer at the SETI Institute where he is involved in many of the outreach activities of the Institute, including editing the newsletter, overseeing the Web site, giving talks and writing magazine articles about SETI. He also teaches several informal education classes on astronomy and other topics in the Bay Area. Before coming to SETI, Seth did research work on galaxies using radio telescopes at observatories and universities in America and Europe. Alex Barnett is Programme Director at the National Space Centre. She is well-known in the science centre, planetarium and media worlds, particularly for public and educational programmes involving space and astronomy. She presents BBC's Final Frontier a space and astronomy programme.

From Hugo and Nebula Award-winning author Robert Silverberg comes, To Open The Sky. The Atom was their God-but there was something stronger... At the beginning of the 22nd century, Earth colonies were established on Mars and Venus. But the ultimate dream - to travel to the stars - was still an impossibility. Cults, fads, madnesses of various kinds swept the population. The maddest--and so far the most permanent--were the Vorst worshipers, the atom adorers, the believers in immortality through technology. Yet there were the Harmonists, who believed that technology could never do it. And the hatred between the two factions was too deep to be reconciled - until a conflict on Venus between a Vorster priest and his Harmonist opponent resulted in unexpected developments.
