Mars’ ocean of 3.5 billion years ago and a star is born

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 glimpsed what could be the youngest known star at the very moment it is being born. Not yet fully developed into a true star, the object is in the earliest stages of star formation and has just begun pulling in matter from a surrounding envelope of gas and dust. See article.
g Abodes - A vast ocean likely covered one-third of the surface of Mars some 3.5 billion years ago, according to a new study. See article.
g Life - Life may be left-handed, but it shows flashes of ambidexterity. That could complicate the search for life on other worlds, but it may also help clear up some puzzling findings from NASA's Viking Mars landers. See article.
g Message - The spectral approach is a universal tool of both astronomical observations and SETI. Furthermore, it has a clear physical meaning – a spectrometer finds the energy distribution of photons, in human sensing it is color and pitch. Under the hypothesis on identity of physical laws in our part of universe, it may be proposed that spectrometry also are using by those aliens, who know radio and lead their own SETI, too. See article. Note: This paper is from 2001.
