Where Did Earth’s Water Come From?

Water is just one big problem facing secular scientists who feel a need to explain everything without design.

Nuts for Aliens

Believers in space aliens, or even space bacteria, have cast all restraint to the wind. SETI today is indistinguishable from a cult, and so is its stepchild, astrobiology.

Planetary Rings Defy Long Ages

Models of the origin of planetary rings are simulations based on fictions. Real physics cannot keep them billions of years old.

Hope, Not Evidence, Drives Astrobiology

Earth-size exoplanets are not evidence for alien life. They are evidence for orbiting bodies.

You Can Trust Scientists (to Be Fallible)

With theory overturns like these, one gets to wonder about the privileged status of scientists in our culture.

Hot Jupiters: Astronomers Blew It

The experts were (and are) wrong about how planets form, new data from a weird exoplanet show.

There's No Place Like Earth

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

Origin-of-Life Speculation Goes Off the Rails

Astrobiologists and their accomplices in the media are finding life everywhere where it isn't or couldn't be. Time to call in the science rangers.

New Thoughts on Habitable Planets

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

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.

Physical and Geological Hurdles on the Darwinian Race

Can the smooth big-bang-to-brain story of evolution jump the physical and geological hurdles along the way?

Astrobiology Hopes Diminish

Recent findings both near and far create challenges for beliefs that life is common in the universe.

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.

Reality Check: Favored Planet Theory Dries Up

Three "hot Jupiters" sing "how dry I am," casting serious doubt on the leading theory of planet formation.

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.
