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.

One would think that the Gliese 581d fiasco would result in more caution. Nah.

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.

Researchers: Planets between 1.7 and 3.9 times the size of Earth were dubbed gas dwarfs since they have thick atmospheres of hydrogen and helium.

The basic problem seems to be that a planet, even in the habitable zone, can mostly be a gasball with a thick, very high pressure atmosphere that would inhibit life as we know it.

Problem – The big recent news has been the discovery of highly complex life forms (comb jellies) from 600 million years ago near the beginning of the life we actually know. Fire and ice are not the source of this complexity

Thus, life-hosting exoplanets may be rarer than hoped.

Why? Because that would make humans’ existence less special.

It is entirely okay to think that Mars is unusual. That is, the solid string of disappointments over life on Mars is not expected to lead to the conclusion that it might be typical, and therefore life might be rare in the galaxy.

What cannot be demonstrated can merely be asserted. Such pronouncements are as definitive as Abracadabra!, and every bit as likely to help us toward the desired prize.

When the exoplanet expert takes up his recently announced appointment at Ball U in Indiana (despite controversy), it would be interesting to see him tackle this question: The narrow, sharp-edged and slightly off-centre rings of dust that surround some stars may be the result of interactions between gas and dust, rather than the gravitational effects […]

Recently some astronomers have dramatically increased their estimates of how many planets in our little corner of the Cosmos might fall in the habitable zone around red dwarf stars! There could be as many as 60,000,000,000 such habitable planets in the Milky Way alone! Based on data from NASA’s planet-hunting Kepler spacecraft, scientists have predicted that […]
