Over on the other thread we’ve had a brief discussion of the recent initiative to find extraterrestrial intelligence. In response to a couple of the comments I thought it might be instructive to look at the logic behind the privileged planet hypothesis, as it relates to the search for life beyond Earth. To that end, […]

Today, Yuri Milner and Stephen Hawking announced a $100M initiative to seek extraterrestrial life, injecting renewed energy (and funds) into the hunt for life (specifically, intelligent life) beyond our fair planet. Although this has been a decades-long area of research and interest, with the SETI institute playing perhaps the most important role in recent years, […]

From Ars Technica: Sometimes, scientists announce things that are breathtakingly stupid. The Guardian, which generally has pretty good science coverage, has an article up reporting that some top scientists believe that the comet 67P may harbor lots and lots of life. The purported evidence for life is the presence of complex hydrocarbons on the comet’s […]

After SpaceX’s “loss of mission.” But are we missing something here? Aldrin, lunar module pilot for Apollo 11, the first manned lunar landing mission here: True, the ripple effects from SpaceX’s Falcon 9 booster going boom in the Florida skies are many. But the take-home message given the NASA-private sector bond is one of striving for reliability, […]

Just ran across this interesting article. I don’t put too much stock into computer simulations of things that are still poorly understood. Indeed, there are plenty of open questions about whether even the basic mechanics of planet formation are understood. But this caught my eye: For planets to be habitable, they must orbit stars within […]

Here. “As a new TIME book explains, a cosmos with trillions of planets does not guarantee more than one with life.” You think that’s bad news? Here’s worse: You are not alone. That other guy is God. 😉 How Do We Grapple with the Idea that ET Might Not Be Out There? This closes our […]

Long suspected: SA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search for […]

Researchers: “We suggest that stars close to the size of the Sun should be the primary targets for detecting Earth-like planets.” Not M dwarfs, as now.

We don’t know if a habitable planet is born every minute, but at least one type of person is.

“We don’t know for sure whether any of the planets in our sample are truly habitable,” explains second author David Kipping of the CfA.

This guy argues that Earth is special, but that that is just a fluke. Possibly that is the only safe thing he can say.

Milky Way centre may be least likely area to host life, but is usual research quest.

The most common explanation for the formation of planet Earth is that it formed by gravitational collapse from a cloud of particles (gas, ice, dust) swirling around the Sun. Specifically, the idea is that small planetesimals form as the various particles clump together (perhaps initially by cohesion, then by gravity), eventually growing into planets. Known […]

Shovelling aside the hype for a moment, ET “signatures of life” are overwhelmingly likely to be something like bacteria.

If only life were a computer model, those planets would be overpopulated already.

Some think that the taxpayer wants and needs to believe in this stuff. If so, New Scientist is sure helping the taxpayer get his money’s worth.

It’s not just that we know very little about the origin of life, but that most of what we think we know is implausible nonsense.
