Facing Reality About Life on Other Planets, 6: Chemistry and Probability

In this final segment about habitability of exoplanets, Dr Henry Richter looks at chemistry and probability.

Facing Reality About Life on Other Planets, 5: Water and Rock

by Dr Henry Richter There is much interest in searching for life elsewhere in the Universe. In previous articles I talked about the many criteria describing conditions and circumstances required to establish and maintain life on a planet. I talked about the importance of the location of the planet in its solar system. The location […]

Facing Reality About Life on Other Planets: Geophysics

by Dr Henry Richter This is a continuation of my discussion on the requirements to allow life to exist on a planet elsewhere in the universe. My discussion moved from our position in the galaxy, our position in the solar system, and then focused on the earth, looking at the influence of our moon, our […]

Facing Reality About Life on Other Planets: Moon, Atmosphere, and Mass

This is part 3 of Dr Henry Richter's discussion on the requirements for life to exist on a planet elsewhere in the universe.

Habitability Requires the Right Kind of Star

This is a continuation of my discussion on the requirements to allow life to exist on a planet elsewhere in the universe.

Facing Reality About Life on Other Planets

by Dr Henry Richter For a number of years I have been amused to watch many in the scientific community conduct a frantic campaign to identify life elsewhere in the universe. There has been a plethora of articles and significant dollars dedicated to the search for extraterrestrial life, particularly intelligent life. In recent times several […]

Earth’s Magnetic Field Protects Us from Solar Sneezes

By capturing solar 'sneezes' of high-energy charged particles, the Van Allen Belts provide a prime example of how the earth and its space environment are designed to allow and protect life.

The Habitability Habit: Exaggerating Earth-Likeness

Secularists put too much hope on some aspects of Earth-like exoplanets, but sometimes reality keeps their imaginations in check.

Your Mind Can Space Out, But Your Body Belongs on Earth

Through the imagination, we can soar through distant galaxies. Sooner or later, physical reality hits home.

What You Are Not Being Told About Earth's Magnetic Field

All you need to know is right here: (1) scientists don't understand it, and (2) without it we would be dead. Read more if you dare.

Hope, Not Evidence, Drives Astrobiology

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

Faint Young Sun Paradox Solved?

A major mystery for materialistic planetary science is solved—if you can swallow the miracles required.

Only Earth Is a Life Haven

Here are more discoveries that make it reasonable to think complex life is rare in the universe, and might be unique to Earth.

More Challenges to Astrobiology

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

Earth Twin Still Missing in Exoplanet Trove

The Kepler spacecraft has found 2,325 exoplanets so far, but there's still no place like Earth.
