Faint hopes easily revived! “Life may be evolving” on closest exoplanet

The fundamental problem is still the same: It is very difficult to extrapolate from a sample of one instance of life. Suppose we had information on tens of thousands of exoplanets, thousands of which had life. Making the reasonable assumption that a pattern develops within this data, we could then give fairly reliable odds on a given planet having life if its relevant data are known. But we don’t have any of this. It’s all a dreamscape.

Stephen Hawkings’ views outside physics were more noted than notable

That’s a common problem when we ask great figures their opinion about things they haven’t studied. From a review of Stephen Hawking’s (1942–2018) last book (or the last book that could be put together plausibly under his name), Brief Answers to the Big Questions: Because of the likelihood of a nuclear confrontation or an environmental catastrophe, […]

Astronomers: First possible exomoon is the size of Neptune, and orbiting a “Jupiter”

An MIT astronomer is 75% certain that an object previously suspected of being an Intro of exomoon (a moon orbiting an exoplanets) really is that: The first confirmed detection of an exomoon would mark a milestone in exploring planetary systems throughout the Galaxy. It would, among other things, allow scientists to test ideas of moon […]

ET life: We should look for planets like Earth’s past, not it’s present

Suggested at New Scientist: There may be life out there that was like life on Earth when Earth was a very different environment: In the 4.5 billion years our planet has existed, it has experienced dramatic transformations: ice ages and warming periods, times when the atmosphere was impossible to breathe, when large areas were desert, […]

Claim: A planet does not need plate tectonics to sustain life

Plus, a friend offers a reply. From ScienceDaily: There may be more habitable planets in the universe than we previously thought, according to Penn State geoscientists, who suggest that plate tectonics — long assumed to be a requirement for suitable conditions for life — are in fact not necessary. When searching for habitable planets or […]

SETI reacts to the new study that says not to wait up for extraterrestrials

From SETI’s Seth Shostak, who surely doesn’t welcome this news, at NBC: A recent paper by three researchers at the University of Oxford is throwing shade on those who feel confident that the cosmos is thick with extraterrestrials. … If we own up to the true extent of these uncertainties and do the requisite math, […]
