Andromeda galaxy lineup, migrating Neptune and faster evolving apes

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 - An unusually high number of galaxies are aligned along a single plane running through the center of the giant Andromeda galaxy. Scientists don’t have a theory to explain why. See article.
g Abodes - The solar system used to be much smaller. According to a new theory, Neptune long ago migrated away from the Sun and forced a vast field of giant boulders out with it. See article. Note: This article is from 2003.
g Life - What are the arguments for the presence of ancient life on Mars? See article.
g Intelligence - While you might think of yourself as smarter than the average ape, beware: Those distant relatives of ours have a knack for evolving more quickly than we do. See article.
g Message - The spectral approach is a universal tool of both astronomical observations and SETI. Furthermore, it has a clear physical meaning – a spectrometer finds the energy distribution of photons, in human sensing it is color and pitch. Under the hypothesis on identity of physical laws in our part of universe, it may be proposed that spectrometry also are using by those aliens, who know radio and lead theirs own SETI, too. See article.
g Cosmicus - New Mexico lawmakers agreed today to proceed on a three-year commitment of funds to build a regional spaceport, designed to support commercial rocket launchings, including passenger-carrying suborbital vehicles. See article.
g Learning - Clues to finding current or past life on Mars now or at some point in the past begins with an examination of Earth's most extreme environments and the adaptable microscopic life that thrives there, according to a group of researchers launched an international broadcast science expedition Jan. 30 with The JASON Project. See article.
g Imagining - Like first contact stories? Then be sure to read Gordon R. Dickson’s novel “The Alien Way” (published by Bantam, 1965).
g Aftermath - How to predict reactions to receipt of evidence for an otherworldly intelligence? Some scientists argue that any unpredictable outcomes can only be judged against our own history. See article.
