Mercury, Moon May Still Be Erupting

Two objects that should be old and dead show surprising activity. Other indications of youthfulness in the solar system are noted.

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.

Curtains for OOL: Oxygen Was Present from the Start

Free oxygen is death to life trying to evolve, but it was present early on, being formed naturally from atmospheric carbon dioxide.

NASA Throws Tax Millions to Evidence-Free Astrobiology Projects

Astrobiology has yet to establish that it has a subject to study, but NASA is giving millions of tax dollars to multiple teams, including SETI researchers.

Lunar Impact: Major Moon Basin Was Not a Big Hit

The theory of how the largest impact basin on the moon was formed has been turned upside down.

Canyons on Earth, Mars Reinterpreted as Flood-Caused

Catastrophic floods formed canyons long thought to have been formed by slow, gradual processes.

Earth as a Habitable Planet

When viewed as a planet among planets, Earth is surprisingly surprising, considering how close it is to scientists' investigating eyes.

Of Planets and People

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

Planets Don't Fit Evolutionary Models

Secular planetary scientists are surprised by almost every object they observe in the solar system. Their models cannot reproduce our system of planets.

Mars Radiation Fries Organic Compounds

Don't expect the "building blocks of life" to last very long on Mars.

Impacts: Creators or Destroyers?

Some astronomers invest a lot of creative power in bangs, crashes and explosions.

Active Moon Triton Revisited

25 years ago today, Voyager 2 flew by Triton, a moon of Neptune, astonishing scientists with its active geology.

Moon Still Has Hot Core

Japanese scientists have determined that a soft, hot core remains in the center of the moon, contrary to expectations.

Fluffballs in Space Shouldn't Exist

A rubble-pile asteroid has such low density it should have disintegrated, but it's doing just fine.

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.
