It's Curtains for Enceladus
May 11, 2015
The geysers of Saturn's little moon are like sheets instead of jets, spelling trouble for theories of its ancient age and possible life.
Evidence-Based Cosmology
March 27, 2015
From what we observe, we can draw inferences without the need to posit occult phenomena.
Comets Are Not Life Givers
December 23, 2014
Astrobiologists dream of comets as bearers of life in spite of—not because of—the data from Rosetta's comet.
Quasar Alignment Is "Spooky"
November 20, 2014
Quasar rotation axes show a peculiar alignment over billions of light-years.
Of Molecules and Men
September 27, 2014
Atoms and molecules are tiny but can have a big influence on the habitability of planets and astrobiologists' theories about them.
Big Bang's Lithium Problem Gets More Problematic
September 15, 2014
There's no escape; new measurements show far less lithium than predicted by the big bang, and more fine tuning than would be expected by chance.
Miller-Urey Spark Discharge Experiment Resurrected
January 21, 2014
Technicians provide detailed instructions how to spark gases to make amino acids without causing explosions in the lab.
Faint Young Sun Paradox Solution Criticized
January 5, 2013
A proposed solution for keeping the Earth warm when the sun was 25% cooler leaves other evolutionists doubtful.
A Young Moon for Life
January 3, 2012
Our moon is unique in the solar system. Just the right size and just the right distance, it is positioned to stabilize the tilt of Earth’s axis, providing stable seasonal cycles. Science lacks data so far to know just how unique the Earth-moon relationship in a habitable zone is among other stellar systems. We know from the planets of our own solar system that moons come in all sizes, from tiny Deimos to massive Titan, and orbit in apparently arbitrary radii from their host planets. What astrophysicists can do is predict what would happen on earth if things were different. That’s what one scientist did. Another discovery could change the view of the moon’s surface being unaltered for billions of years.
Don’t PNA in our OOL
December 17, 2005
Theories for the origin of life (OOL) are in a crisis, unable to imagine how something as complex as a replicating cell could come into existence. Could PNA do it?
