Drill for Europa’s ice and how far away is 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 - Four billion years ago, the Sun radiated less energy than it does today. Scientists once believed that greenhouse gases must have helped the Earth stay warm during this time. However, new research shows that the large oceans may have simply absorbed more heat. See article.
g Intelligence - How many light-years is it to the nearest alien civilization? See article. Note: This article is from 2001.
g Message - Sorting deliberate signals from a gush of cosmic static requires discernment. It’s somewhat akin to beachcombing: finding the occasional bauble on a shoreline littered with dead seaweed, desiccated crustaceans, and other unappealing, sea-borne dross. See article. Note: This article is from 2003.
g Cosmicus - NASA and the European Space Agency are sending a mission to study Jupiter and its moon Europa in 2020. There may be life in the moon’s ocean, but to find out a mission will have to be able to drill down through the overlying ice shell. See article.
