Carbon emission line from most distant galaxy known so far

Carbon emission line from most distant galaxy known so far 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 - Astronomers have detected a carbon emission line from the most distant galaxy known so far. The faint galaxy shows that carbon existed less than a billion years after the Big Bang. Determining the composition of the early Universe can help astrobiologists understand when and where habitable planets could have formed. See article.
g Abodes - ESA's Venus Express has discovered an ozone layer on Venus. Comparing Venus' ozone layer to those on Earth and Mars will help astrobiologists refine the search for life on other planets. Comparing Venus to Earth can also help scientists better understand the principles of climate change on our own planet. See article.
g Message - The Earth's radio emission is now comparable to or stronger than the Sun's. So for aliens looking in the radio frequency, we should be the brightest spot in the solar system. See article.
