Good news for finding fossils on Mars and ETI signals beamed at Earth

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 preliminary analysis of elderly stars in the Milky Way appears to strike a blow against the prevailing theory of galaxy formation. The study suggests that several large and seemingly disparate chunks of the Milky Way galaxy formed at the same time from the collapse of a single blob of gas and dust. See article.
g Abodes - Astronomers have imaged three distant exoplanets using only a modest-sized, ground-based telescope. The surprising feat could be repeated using larger telescopes, providing more information about exoplanets than previously thought possible with current technology. See article.
g Life - Tiny fossils discovered on Earth in samples of sulfates, a class of minerals recently found to be common in some parts of Mars, bodes well for finding vestiges of life on the Red Planet, astrobiologists reported. See article.
g Message - Since the invention of the radio, humans have been broadcasting signals into outer space. Other civilizations in our galaxy might be doing the same. They might even be deliberately sending out signals to find other civilizations. Someone out there may even be beaming a signal directly at the Earth. See article.
g Cosmicus - NASA engineers catapulted the new Orion crew capsule about a mile into the air Thursday morning as hundreds of people gathered to watch. See article.
