Researcher Denies SETI Is a Religion
June 3, 2006
Apparently irritated by charges that SETI research is like a religion (see, for instance, the article by novelist Michael Crichton mentioned in our 12/27/2003 entry), David Darling of the SETI Institute has issued a response.  On Space.com, his title was direct: “Of Faith and Facts: Is SETI a Religion?”  The answer was a forthright NO […]

Asteroid Sticks Together While Theories Disintegrate
June 1, 2006
[Guest article]  In an story entitled “Rubbly Itokawa revealed as ‘impossible’ asteroid,” New Scientist Space reported on findings gathered from the recent visit of Japanese spacecraft Hayabusa to the asteroid Itokawa (see 11/28/2005 bullet).  There seems to be no end of problems for scientists trying to fit the solar system into billions of years.  Now […]

Paper View:  Cosmic Questions, Personal Implications
May 11, 2006
A good question provokes good thinking.  It stimulates the imagination and inspires reasoning about profound issues.  It focuses attention on problems, calls for clarification of assumptions, and leads to good follow-up questions, too.  Such a good question was asked in four simple words by Sean M. Carroll1 (U of Chicago, Enrico Fermi Institute) this month […]

See Comet Crumble
May 10, 2006
A comet is breaking up before our eyes.  Comet Schwassmann-Wachmann 3 has split into dozens of pieces and is crumbling quickly, like pieces of dried meringue.  Science News tells about the breakup, and it made Astronomy Picture of the Day.  The Hubble and Spitzer space telescopes are also documenting the event.     This is […]

The Porridge Before the Soup: Too Hot?
May 8, 2006
In the evolutionary theory of everything, there is a soup before the primordial soup we normally think of.  It’s the solar nebula, the whirling disk of dust, gas and ice that preceded the planets.  Scientists used to think the nebula was differentiated like chemicals in a giant centrifuge, with the rocks close to the sun […]

Hope for Titan Ocean Evaporates into Ice Desert
May 4, 2006
Saturn’s moon Titan is a desert of sand made of ice grains mixed with hydrocarbons.  These grains form large fields of wind-driven dunes found over much of the planet-sized moon.  “Titan’s Seas Are Sand,” reported a press release from U of Arizona based on a paper in the May 5 issue of Science (see Perspective […]

Solar Eclipses Unique to Earth, SETI Researcher “Finds”
May 4, 2006
Like many before him, Seth Shostak pondered the significance of total solar eclipses for the one planet with observers to appreciate them.  “OK, I’ve done the math,” the SETI Institute director said for SETI Thursday on Space.com.  “What you always suspected might be true … is true: namely that the best place in the solar […]

Unconstant Constant Could Challenge Basic Physics
April 27, 2006
“Shifting constant could shake laws of nature,” said Mark Peplow in Nature.1  “From the speed of light to the charge on an electron, the fundamental constants of physics had been assumed to be immutable,” he continued.  “But that comfortable assumption is being challenged.”  The latest challenge is ratio of the mass of a proton to […]

Astrobiology Ten Years Later: Can It Justify Its Funding?
April 17, 2006
Astrobiology just turned ten years old, but is experiencing growing pains, partly due to a starvation diet.  This “science without a subject” (as George Gaylord Simpson quipped about its predecessor, exobiology) is struggling to justify itself at the Congressional feeding trough.  Proponents tout it as the most important subject in the universe.  Why, then, is […]

“Fertile Imagination” Envisions Life on Titan
April 4, 2006
The dramatic landing of the Huygens Probe on Titan over a year ago (01/14/2005, 01/21/2005, 12/05/2005) is finally getting some overdue notice from the media.  The PBS science series NOVA just aired a new program on Cassini-Huygens, “Voyage to the Mystery Moon” (see your local PBS station for rebroadcast times), and Astronomy Magazine’s May 2006 […]

More Hints at Early Origin of Stars, Galaxies
March 31, 2006
Several articles this month showed further evidence for a growing realization in astronomy: stars and galaxies were already mature at the beginning of the universe (see, for instance, 09/21/2005 entry).  Some recent examples: Spitzer Clusters:  JPL issued a press release stating that the Spitzer Space Telescope, on a “cosmic safari,” found evidence for clusters of […]

Dry-Marsers Score Points
March 23, 2006
Those looking for water on Mars in hopes that life would grow in it had some setbacks this week.  National Geographic and Mars Daily reported on work by Gwendolyn Bart (U of Arizona) who found gullies on the moon similar to those on Mars thought to be formed by water.  Since the moon never had […]

Planet-Making a Lost Art
March 21, 2006
Exclusive  Solar system theorists are trying to reverse engineer the planets without the recipe.  Planets exist, but they can’t get from a rotating disk of dust and gas to a solar system from their models.  They are at a loss to explain Jupiter, Saturn, Uranus, Neptune and a host of Jupiter-class planets around other stars.

The Astrobiology Sky Is Falling
March 13, 2006
Rocco Mancinelli (Principal Investigator, SETI Institute) made an impassioned plea on Space.com for continued funding of astrobiology projects, calling threatened funding cuts a “national disaster” if not reversed.  And what is astrobiology?  He defined it as “the study of the origin, evolution, distribution, and future of life in the universe.”  His reasons for keeping astrobiology […]
