ETI listening for radio signals and finding Mars in Morocco

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 - A dying star has been spotted coughing up a toxic mix of gases in a spectacular new photo from the Hubble Space Telescope. See article.
g Abodes - Scientists have found that calcium, aluminum-rich inclusions, some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system. The findings may lead to a greater understanding of how our solar system and possibly other solar systems formed and evolved. See article.
g Life - Fossilized bones discovered in Texas from a flying reptile that died 89 million years ago may be the earliest occurrence of the prehistoric creature known as Pteranodon. See article.
g Intelligence - What happened to being "quiet as a mouse"? Researchers have recently shown that, rather than being the silent creatures of popular belief, mice emit ultrasonic calls in a variety of social contexts, and these calls have song-like characteristics. So if mice sing, where do they get their music? Are they born with the songs fully formed in their heads, or do they learn them from their peers? See article.
g Message - While advanced civilizations might be tempted to use optical means such as lasers to send information between the stars, there are some good reasons that nearly all the major Search for Extraterrestrial Intelligence experiments are looking for radio waves instead. See article. This article is from 1996.
g Cosmicus - Martian-like landscapes in Morocco provide testing grounds for the next generation of Mars exploration missions. See article.
