Hot Jupiter aurorae affects habitability of rocky planets and ‘Worms from Hell’

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 - New research indicates aurorae on hot Jupiter planets around distant stars could be 100-1000 times brighter than those on Earth. The work has implications for the habitability of small, rocky exoplanets. See article.
g Life - Worms found miles underground in South African mines surprised scientists, because they never thought complex life could reside at such depths. These "worms from Hell" add to our understanding of life on Earth, and make us rethink assumptions about how complex life could be on Mars or other planets. See article.
g Message - The drive to place humanity at the center of the universe has led to a stream of assumptions that, as facts have been collected, are shown to be ill founded. The Ptolemaic Earth centered view was replaced by Copernican Sun centered view, which in its time was also replaced. The assumption that we are alone in the universe is also under threat of replacement. One of the more interesting aspects of our apparent aloneness was pointed out by Enrico Fermi and is known as Fermi's Paradox. See article.
