Solar system similar to our own discovered and how to find a complex message from ETI

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Astronomers have discovered a group of at least five planets – with hints of two more – circling around a star in an arrangement similar to our own solar system. Confirmation of the extra planets would make this the highest tally of alien worlds ever spotted around a single star. See article.
g Abodes - If we could make one change to stave off climate change, what would it be? One scientist believes that getting rid of black soot is the answer. Other research shows that fighting climate change with geo-engineering tricks, such as pumping out aerosols to reflect sunlight, may not be a solution. See article.
g Message - The investigation of new transmission modes hints that if we do find a signal from ET, we may wish to reconfigure our radio telescopes to look for encoding of the message via such subtle effects as orbital angular momentum. A simple signal may only be a cipher for a more complex message. See article. This article is from 2008.
g Aftermath - Alien encounters and science fiction permeate pop culture, but what would it really mean if scientists found life beyond Earth? If even a single-celled organism on another planet was discovered, for many, this would be the last thread of evidence proving that life is simply chemistry. See article. This article is from 2003.
