Exoworld orbits in opposite direction of star and consequences of receiving a signal from the cosmos

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 - New research shows that an unusual mix of stars at the center of our galaxy might be the remnants of a dwarf galaxy that merged with the Milky Way long ago. The findings could help astrobiolgists understand how galaxies evolve and, ultimately, the processes behind solar system and planet formation. See article.
g Abodes - The exoplanet HAT-P-7b has been observed to have a very curious orbit. It either has a highly tilted orbit – passing almost over the poles of its parent star, HAT-P-7 - or a retrograde orbit; that is, orbiting in the opposite direction of its parent star. See article.
g Life - For astrobiologists, it is very important to distinguish between living and inert beings. See article.
g Message - The search for extraterrestrial visitation is motivated not only by the writings of other authors on the subject of interstellar probes, but also by the awareness of the progression of our own probe technology. Included in this awareness are Earth's advancements in communication technology, growing understanding of exobiology and ongoing research of new possibilities to enable travel across vast distances. See article.
g Cosmicus - How we define "exploration" may set the success or failure of NASA's future. See article.
g Aftermath - Book alert: In their November 2003 book “In Cosmic Company: The Search for Life in the Universe,” authors Seth Shostak and Alex Barnett ponder the possibility of alien life and the consequences of receiving a signal from the cosmos. They explain why scientists think sentient life might exist on other worlds, how we could discover it and what it might be like. Entertaining and informative, this hard cover book is lavishly illustrated. See reviews.
