@arstechnica it won't be helped by Trump's proposed 50% cuts to NASA either.

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious. Using data from the James Webb Space Telescope (JWST), the astronomers, have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), in the atmosphere of the exoplanet K2-18b, which orbits its star in the habitable zone.

@setiinstitute It's not impossible for Tardigrades to have made it out to Alpha Centauri.....
Do I think Elon Musk is so racist that he hates actual Space Aliens and will close down anything SETI or Exobiological at NASA?
I guess we're going to find out, aren't we?
Thinking that there could be planets out the which are nothing but Fungi and they could outnumber the planets like ours.
Last night, I found a planet worth over 180 million creds in exobio data. 9 species.

Sci.News: Breaking Science News · Purple is the New Green: Purple Bacteria Could Dominate Wide Range of Exoplanetary Environments | Sci.NewsUsing life on Earth as a guide, astrobiologists from Cornell University and the University of Minnesota looked beyond green landscapes to expand their ability to detect signs of surface life on other worlds.
When I say that a type of complex system, e.g. a form of government or a proselytizing religion, meets the minimum requirements (self-similar reproduction and mutation) for biological evolution to take place, I think a lot of people miss the most important implication of this:
The system has *agency*, independent of its constituent elements.
Governments and proselytizing religions can be legitimately said to have a will of their own. They have their own "best interests" which dictate their behavior. The longer these systems are subject to biological evolution, the more apparent this will become in their behavior, as they are continually shaped to maximize their own homeostasis and reproductive success through their behavioral tendencies.

@glynmoody I won't get TOO excited... I remember the 'Mars rock' in the late 90s and how it was slowly but surely shown to be probably NOT bacterial traces -- but this is at least hopeful. Yes, I want to believe. But I won't. Not YET.

1. “Imagine we land a space probe on one of Jupiters’ moons, take up a sample of material, and find it is full of organic molecules. How can we tell whether those molecules are just randomly assembled goo or the outcome of some evolutionary process taking place on the planet?”
I've written a new blog entry about some of the current approaches to searching for extraterrestrial life.

ovid.github.ioSearching for Alien LifeThe title seems like clickbait, but it's real. There's not only amazing research being done on the origin of life, but there are extremely intriguing results out there.
"Why finding alien life in Universe is now 'only a matter of time'"
Indeed, and like one of the scientists referenced in this piece, I'd be surprised if there was no life on one of Jupiter's icy moons. Europa is the most likely candidate.
BBC NewsAlien life in Universe: Scientists say finding it is 'only a matter of time'Experts are optimistic of detecting life signs on a faraway world within our lifetimes - possibly in the next few years.
