Searching for ETI south of the equator and Rosetta Stone for T-dwarf stars

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 international team of astronomers have discovered a unique and exotic star system with a very cool methane-rich (or T-) dwarf star and a “dying” white dwarf stellar remnant in orbit around each other. The system is a “Rosetta Stone” for T-dwarf stars, giving scientists the first good handle on their mass and age. See article.
g Abodes - An international research team has found evidence for reservoirs of liquid water on Mars at shallow crustal depths of as little as tens of meters. See article.
g Life - Researchers have discovered bacteria and algae that have been trapped inside fluid inclusions in salt crystals for thousands of years. The study could provide direct observations of how organisms have evolved over time and reacted to climate change on the ancient Earth. See article.
g Message - What are our friends south of the equator doing in the search for extraterrestrial intelligence? After all, the Northern Hemisphere only covers half of the galaxy. See article.
g Cosmicus - Space Exploration Technologies, the California company called SpaceX for short, has received the first-ever commercial license to re-enter spaceships from Earth orbit. See article.
