The sounds of extrasolar planets and how will we react to ETI?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars - What is the habitable zone for the nearby star system Gliese 1245 ABC?
See article.
g Abodes -Scientists are beginning to understand radio emissions emitted by aurora on Earth. The new study will help future astronomers search for extrasolar planets by listening for the sounds they make. See article.
g Message - A recent study suggests it is more energy efficient to communicate across interstellar space by sending physical material — a sort of message in a bottle — than beams of electromagnetic radiation. Solid matter can hold more information and journey farther than radio waves, which disperse as they travel. See article.
g Aftermath - Astronomers are searching hard for that first interstellar phone-call from ET. But when it happens, how will we react? Will it be a major trauma for humankind, or a new beginning? See article. Note: This article is a few years old.
