Types of stars that could support Earth-like worlds and what to say to ETI

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Jupiter is often credited for shielding Earth from catastrophic asteroid and comet impacts. But new simulations of the influence of gas giant planets in solar systems casts doubt on Jupiter's reputation as Earth's protector. See article.
g Life - Photosynthesis maintains Earth's habitability for life as we know it, and shapes the way we search for habitable worlds around distant stars. Scientists have discovered a microbe that can use low-energy light to perform photosynthesis. This discovery could alter theories about the types of stars that could support Earth-like worlds. See article.
g Message - If anybody's out there, what do we tell them? See article.
g Cosmicus - Origins missions are designed to observe the birth of the earliest galaxies and the formation of stars, to find all the planetary systems in our solar neighborhood, to find planets that are capable of harboring life and to learn to what extent life exists beyond our solar system. We do this to understand the origins of our world. We do this to answer two questions: Where did we come from? Are we alone? See article.
