Natural Selection Favors Illogic

Nothing in Darwin's mechanism guarantees humans will think rationally. Fitness might actually favor stupidity. For proof, look at the reasoning of people who believe in natural selection.

More Challenges to Astrobiology

There aren't likely as many places to live outside of Earth as earlier hoped.

Scientists Going Nuts Over Aliens

Baseless speculations are considered perfectly sane as long as you are a secular materialist.

More Indications Earth Is Unique

The late Carl Sagan might be stunned to see today's astronomers questioning Earth's "humdrum" status.

There's No Place Like Earth

A survey of known exoplanets finds no real estate as valuable as Earth.

New Thoughts on Habitable Planets

Astrobiologists are trying to standardize the requirements for habitable planets. Do they get them all?

Do You Know How Lucky You Are to Live on Earth?

The factors that make life possible came together so beautifully, even materialists have trouble knowing why we're here.

You Wouldn't Want to Live on "Earth's Cousin"

Despite the hype about another Earth-like exoplanet, Kepler 452b would not be as habitable as Venus.

Moon's Stabilizing Influence Depends on Star Size

A connection between multiple factors was noted in a recent model of how a moon helps a planet remain habitable.

Of Planets and People

Here's a quick tour of the planets to see what's newsworthy.

Planet Rotation Limits Habitability

Life can't exist on a planet that rotates too fast or slow. This is another Goldilocks problem for astrobiologists to consider.

Without Bromine, There Would Be No Animals

A 28th element has proven to be essential for life: bromine.

To Be Habitable, a Planet Needs Inhabitants

In a chicken-or-egg conundrum, astrobiologists are asking whether inhabitants are needed to make a planet habitable.

Astrobiology Hopes Dim with Exoplanet Findings

Harsh "space weather" around dim red dwarf stars may make planets uninhabitable. "Godzilla Earths" may not fare much better.

Stellar Dust Disks Crumble

Observations show stellar dust disks fragmenting into smaller dust, not growing into planets.

New Craters Found on Mars

Orbiters can count new craters forming on Mars, refining cratering rates. One spectacular new crater has appeared since 2010 with vivid rays.

Imagining Worlds – No Evidence Required

Science fiction is fun, but science demands evidence, not imagination.

Cosmic Lottery: How Many Habitable Planets?

News media ran with a suggestion that one in five stars has a habitable planet, but they didn't read the fine print.

Planet Habitable Zone Cannot Be Too Windy

The "habitable zone" of a planet usually concerns its distance from the star such that it can support liquid water. But what if the star fries the surface with intense stellar winds?
