…The scientists are careful to emphasize, as they do in their current paper, that “complex organic chemistry is of course not life, but there is no life without it.” In…
Exoplanet ocean currents may follow a pattern that scientists can use to track down life outside of our solar system. In search for alien life, planets exactly like Earth may…
…simple rules can emerge incredibly complex behaviors. One of the best-known cellular automata, called The Game of Life or Conway’s Game of Life, was developed by English mathematician John Conway…
A recent study led by SETI Institute Senior Research Scientist Kim Warren-Rhodes and published in Nature Astronomy brings us closer to discovering extraterrestrial life by mapping scarce life forms in…

…Using computer models of the climates and biospheres, astrobiologists are researching how signs of life might look on dying planets. If life does exist anywhere else in the universe, it…
…how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility…
…outgrowth of NASA’s broader search for life beyond Earth. And he says technosignatures, defined as evidence of advanced life, are a subset of biosignatures – evidence of all biological life,…
…building a tree of life for all 330,000 known species of flowering plants—a massive undertaking byKew’s Tree of Life Initiative. “Analyzing this unprecedented amount of data to decode the information…
…extraterrestrial amino acids. Unraveling Molecular Orientations in Life’s Origins The mystery of why life relies on molecules with specific orientations has deepened following a NASA-funded discovery about RNA. RNA, a…
