Well, first, the BBC asks: What makes a planet habitable? Here: Water in liquid form is thought to be a necessity for life on Earth. Based on this, let’s look at the classical definition for the habitable zone as the region around a star, such as our own Sun, where the temperature of any orbiting […]

From Science: Why water worlds won’t host life New research published online before print in the Monthly Notices of the Royal Astronomical Society shows that Earth-sized water worlds are habitable only in a very limited range of temperatures—from about 0̊C to 127̊C. Anything outside that range, which tends to occur on planets that are in […]

Further to: Physicist Paul Davies’ killer argument against the multiverse (Vincent, Torley), here’s physicist and author Davies on the search for extraterrestrial life: A huge investment into the search for intelligent alien life has renewed public interest in the question of whether we’re alone in the universe. Paul Davies tells Late Night Live why he’s […]

Further to NASA says new Earth-like planet found (which may or may not be actually Earth-like), the question was raised, “Is there an accepted hypothesis on the subject of whether Earth-like conditions are essential to life?” Physicist Rob Sheldon writes to say, Like most other things involving life, NASA is schizophrenic about the subject. Darwinists […]

Further to: NASA says new Earth-like planet found: from Real Clear Science: Another problem is that Kepler-452b is alone. As far as we know, there are no other planets in the same system. This is an issue because it was most likely our giant gas planets that helped direct water to Earth. At our position […]

Here: Nasa scientists have announced the discovery of Kepler 452b, also known as ‘Earth 2.0’, an earth-like planet in our galaxy. Over the course of years of data-gathering by the Kepler space telescope and even more analysis and work here on Earth, scientists confirmed the existence of the distant exoplanet, which is the most earth-like […]

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.

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