Habitable Planets
Strangulation Efficiency in Galaxy Clusters
Kawata and Mulchaey’s discovery arose from a detailed chemodynamical simulation of how neighboring galaxies and gas clouds impact the star formation history of a disk galaxy.1 (All spiral … more
Is Life Possible on a Moon?
A team of American astronomers recently announced the discovery of the first known planet outside our solar system to spend its entire orbit within the “habitable zone.”1When astronomers … more
Does the Probability for ETI = 1?
Earlier this fall (September 25) I had a three-minute debate on Mancow’s Morning Madhouse, a nationally syndicated radio show, on the topic “Is there scientific evidence for intelligent … more
Planet Migration Tests Solar System Design
Astronomers have discovered over 250 planets outside of our solar system residing in over 200 different planetary systems. However, all of these extrasolar planets exhibit characteristics that would … more
Continental Landmass Growth and the Genesis 1 Chronology
The breakthrough yields yet more evidence for the divine inspiration of the Bible’s words and message. First, let me offer some personal background for this discovery.
I signed my name in the … more
Searching for Earths
I once saw a toy that served as a visual example of the saying "one in a million". It consisted of a clear plastic ball about 4 inches in diameter filled with literally a million little plastic cubes. … more
Planet Rotation Design
If the planet rotates too slowly, the temperature differences between day and night will become too extreme. If the planet rotates too quickly, the jet streams will become too laminar and too stable, … more
Effect of Distant Orbiters on Habitability
A recent study by an MIT astronomer of a distantly orbiting companion to the nearby planet-hosting star HD 3651 illustrates the problems a distant relative can pose for any possible life-supportable … more
Why We Need to Return to the Moon
The Apollo missions were more than just television spectaculars, however. The Apollo program helped us solve the mystery of the moon’s origin and helped establish how amazingly designed the moon … more
Follow the Water...to Life?
However, despite a quadrupling of funds in just six years (compared to a vastly smaller increase for all the other sciences) and despite decades of diligent searching, no one has found any evidence … more
Exotic Life Sites: The Feasibility of Far-Out Habitats
Most questioners are looking for a particular answer. Science fiction novels, The Planetary Society, and countless movies, from E.T. to Contact to Planet of the Apes, suggest that extraterrestrial … more
Search for Planets Draws a Blank
Is the universe really rife with life sites, as Carl Sagan asserted?1 Research data continues to shape an answer to this question, but the weight of evidence falls, thus far, on the negative side. The … more
Aliens From Another World? Getting Here From There
Growing numbers of UFO and ETI cults, some overtly religious, others with the pretense of purely scientific endeavor, preach their own message of salvation for the human race, a message that directly … more
First Detection of Earth-sized Planet?
A team of 41 astronomers from Australia, Japan, New Zealand, and the United States took advantage of a naturally occurring telescope to image a small planet orbiting a star somewhere between us and … more
Live Here or Nowhere
In the latter half of this decade, science revealed the importance of our solar system’s position in the galaxy between two spiral arms, where certain life-disturbing phenomena rarely occur and … more
Life Zones in Space
No wonder these systems hold such fascination for scientists, for everyone! In October 1999, Science focused an entire edition on planetary systems. It featured a dozen papers on the topic, including … more
A Twin or Not a Twin?
Recent studies of the Edgeworth-Kuiper asteroid belt reveal the “amazing circumstances” required to make our solar system a suitable place for life.1 The belt itself is a recent discovery. … more
The Heavens Resound with a Message for Mankind
Their investigation of planetary resonances (the intensification of gravitational effects resulting from orbital patterns and repeated, regular planetary alignments) indicates that without an … more
A Spectrum of Views on ETI
by Sam Conner, Dr. Guillermo Gonzalez, and Dr. Hugh Ross
The “Christian position” on extraterrestrial intelligence (ETI) has been a matter of debate since the time of Thomas Aquinas.1, 2 … more
