If life is “a cosmic imperative that emerges on any mineral- and water-rich world,” say the researchers, then life emerged early on Earth along with minerals.
Rock samples collected from Mars by NASA’s Curiosity rover have revealed signs of key ingredients of life, according to a statement by the agency.
University of Cambridge researchers conclude, “The unusual behavior of sulphur in Venus’ atmosphere cannot be explained by an ‘aerial’ form of extra-terrestrial life, according to a new study.”
NASA is officially joining the hunt for UFOs. The space agency on Thursday announced a new study that will recruit leading scientists to examine unidentified aerial phenomena.
Biochemist Fuz Rana discusses a 2020 review article published in the journal Life in which a team of astrobiologists from MIT present a detailed evaluation of silicon’s life-support capacity.
Ethan Siegel: Thanks to its unique, unprecedented capabilities, JWST might answer five currently open questions about the Universe in very surprising ways.
Many life forms eat and breathe things we used to think were lethal. Life seems to want to come into existence any way it can. Exoplanets may well offer suitable environments.
Witze: More than fifteen months after landing in Jezero Crater on Mars, NASA’s Perseverance rover has finally begun its hunt for ancient life in earnest.
An intelligent design approach to the universe is a better bet for finding life elsewhere than Darwinian randomness is.
To sum up, whatever we see or read about planets in science fiction, something out there is likely stranger still. It will be most interesting to see how many of the more conventional exoplanets have life and if there is in fact a reliable formula for predicting it. Those who claim that Earth is just an ordinary planet are certainly wrong — but is Earth unique? The universe is fine-tuned, as is Earth, and that would be an argument for life on exoplanets.
Researcher: “If the mechanism we see in Greenland is how these things happen on Europa, it suggests there’s water everywhere.”
His reasons would suggest that human intelligence cannot simply be a product of evolution, whether he realizes that or not.
C. .S. Lewis: The Supernatural is not remote and abstruse: it is a matter of daily and hourly experience, as intimate as breathing.”
The idea is to give media some idea of the level of confidence in what the apparent signal might be telling us — biological activity or just chemistry?
Takehome: Extremophiles — life forms that live under extreme conditions — are showing that survival of life is a much less severe problem than origin of life.
