Extraterrestrial life

Barack Obama implies, maybe, keep the space alien thing going…

Say what you want, the aliens are good for the cultural fluff news business, whether they exist or not. Better, on the whole, if they don't. Just like if you own an inn and you can somehow get a reputation for it that it is haunted, you'll get lots of free publicity (= advertising). Read More ›

At Science: Water bears most likely did not survive a crash land on the moon

What impact does the test have on panspermia, the hypothesis that life might travel between planets via comets? "some parts of a meteorite impacting Earth or Mars would experience lower shock pressures that a tardigrade could live through, Traspas says." Read More ›

Worry of the month: Could humans have contaminated Mars with life?

Christopher Mason: There is a chance, however, that if we do detect signs of life on Mars, it could have come from Earth in the first place. Ever since the first two Soviet probes landed on the Martian surface in 1971, followed by the US Viking 1 lander in 1976, there likely have been some fragments of microbial, and maybe human DNA, on the Red Planet.

China lands Rover on Mars to look for water, life

National Geographic: Utopia Planitia, thought to be the site of an ancient sea, has sedimentary layers that could contain evidence of past water. Even more exciting, these layers of rock could contain traces of any past life on Mars, says James Head III, a planetary scientist at Brown University. Read More ›

Saturday night: Ex-Pentagon whistleblower warns of UFO 9-11

The remarkable thing is that we haven’t found so much as a fossil bacterium in recent Mars samples. The belief that whatever’s weird out there must be aliens is a sheer act of faith. The same people who would dismiss massive evidence for design in the universe and life forms believe in ET with no evidence at all. That’s probably because, at heart, their commitment is one of the few types of religion that naturalism permits. Read More ›

Is there a law of evolution? Can it predict what aliens would be like?

Kershenbaum wipes out, unfortunately, when he tries to claim that human culture is genetically based. Read More ›

Researchers: We might find extraterrestrial life in 5 to 10 years

Researchers: The new James Webb Space Telescope, which launches in October, “could feasibly detect ammonia around six gas dwarf planets after just a few orbits” Read More ›

“‘Oumuamua is a spacecraft!” astronomer has come up with a SENSIBLE idea: Search the Moon

Avi Loeb has come up with a very reasonable idea for searching for evidence of other civilizations in our galaxy: Look for alien debris on our still, lifeless, atmosphere-free Moon. Read More ›

Sabine Hossenfelder asks: Whatever happened to life on Venus?

Hossenfelder ends by reminding us, re phosphine on Venus, that “ absence of evidence is not evidence of absence.” True, but that’s just a corollary of the fact that one can’t prove a negative. No, we can’t but that doesn’t prevent us from drawing reasonable conclusions. The proverb has been used to cover far too many situations where a more realistic conclusion would be “There is no particular reason to believe this.” Read More ›

At Mind Matters News: What if extraterrestrials can’t afford to take chances with us?

The Dark Forest Hypothesis assumes that we can use sociology to figure out what extraterrestrial intelligences might be like or might want. But can we? What's become of sociology these days? Read More ›
