Young Galaxy Cluster Already Mature
March 9, 2011
“Isn’t that special.”  The remark, in common parlance, is a generic way of avoiding a judgment call.  When astronomers were confronted with the sight of a galaxy too mature for its age, Space.com reported the response: “And that makes it special, researchers said.”     The headline was, “Surprise!  Ancient Galaxy Cluster Still Looks Young.”  […]

Enceladus Geyser Heat Much Higher Than Thought Possible
March 7, 2011
The Enceladus problem – accounting for the heat source of a tiny moon of Saturn – just jumped by more than an order of magnitude.  “Cassini Finds Enceladus Is a Powerhouse,” reported Jet Propulsion Laboratory today.  “Heat output from the south polar region of Saturn’s moon Enceladus is much greater than was previously thought possible,” […]

Alien Life in Meteorites Claimed
March 6, 2011
After scrutinizing rare meteorites for over a decade, a NASA astrobiologist decided to go with his announcement: he may have found alien life.  Fox News began his story, “We are not alone in the universe – and alien life forms may have a lot more in common with life on Earth than we had previously […]

Philosophy Roundup
February 27, 2011
Philosophy of science is a broad discipline incorporating many sub-disciplines such as intellectual history, sociology, ethics, rhetoric, logic, demarcation of science from pseudoscience, classification, discovery, verification, explanation and more.  A dozen recent news stories discussed some of these topics. Medical ethics:  PhysOrg reproduced an AP story about medical research on humans in the US in […]

Habitable Zones Constrained by Tides
February 26, 2011
The idea of a circumstellar habitable zone – a radial range around a star where an earth-like planet could support life – may be too simplistic.  Science Daily reported that “Tides can render the so-called ‘habitable zone’ around low-mass stars uninhabitable.”  Astronomers at the Astrophysical Institute Potsdam studied the effects of tides on planets around […]

Busted!  Planet-Making Theories Don’t Fit Extrasolar Planets
February 23, 2011
Famed planet-hunter Geoff Marcy is giving theorists headaches.  The leading theories of planet formation won’t stand up to observations of hundreds of planets we know.  In National Geographic News reporter Richard Lovett lamented, “The more new planets we find, the less we seem to know about how planetary systems are born, according to a leading […]

Is Star Formation Understood?
February 22, 2011
Astronomers often speak with apparent confidence about regions of active star formation in nebulae or galaxies. A look at the fine print, however, shows plenty of wiggle room when observations don’t quite match theory.

Titan’s Methane Lakes Shallow, Dynamic
February 19, 2011
Strange things are happening on Titan, Saturn’s largest moon: lakes are appearing and disappearing.  This can only mean that the lakes are shallow and the liquid hydrocarbons in them are moving around.     Lakes were discovered a few years ago in the northern regions of the Mercury-size moon.  They consist predominantly of methane (CH4) […]

Intelligence as a Cosmic Reality
February 6, 2011
The “I” in SETI takes “Intelligence” seriously.  It requires that intelligence is a recognizable, quantifiable property of nature.  The origin of intelligence is a question that separates theists from materialists – whether it is a fundamental or emergent property.  Before engaging that question, it might be instructive to see how scientists who are not necessarily […]

Martian Chronicles
February 3, 2011
Recent news stories about Mars can be categorized into past, present, and future. Mars past:  How Mars formed is a convoluted story.  That is evident from a report on PhysOrg that might suggest Mars modelers are drinking too much to relieve stress: “‘Marstinis’ could help explain why the red planet is so small.”  Mars seems […]

Planets a-Plenty, but Are They Lively?
February 2, 2011
The Kepler spacecraft has found over 1,235 planets so far (Space.com), 54 in their star’s habitable zone, and some Earth-size or smaller.  Science media are having a field day reporting the discoveries, portraying them with artist imaginations, licking their chops at the possibility of life in outer space.  What does this mean?     Space.com […]

Scientists Debunk Scientists
January 12, 2011
What do you know?  We look to science to tell us about reality, but how confident can we be when they keep changing the tune? Undermining cosmology:  Science Daily tells us today that “Cosmology Standard Candle Not So Standard After All.”  Results from the Spitzer Space Telescope show that Cepheid variables shrink as they age, […]

SETI’s Monsters Under the Head
January 11, 2011
No one has ever proven the existence of life beyond the earth, but some people have the earth’s international response all worked out.  They know how we should react whether the aliens are friendly or hostile.  Mike Wall at Space.com published the idea that if we are not alone, we should fear the aliens.  But […]

Loopy Cosmology Goes Abstract
December 17, 2010
A physicist from Warsaw standing by a Picasso painting finds convergence with his thinking about the origin of the universe.  The caption on Science Daily reads, “The lines in the painting are fairly similar to graphs showing the evolution of quantum states of the gravitational field in loop quantum gravity.”  The cosmologist is Prof. Jerzy […]

SETI Ignorance Gets Stronger
December 9, 2010
“Science is not about blind faith” begins a video posted on MSNBC about SETI.  Part of an article by AP reporter Seth Borenstein, “Evidence for E.T. is mounting daily, but not proven,” the video explains Frank Drake’s famous equation that tries to quantify the probability for extraterrestrial intelligence (09/29/2010, 11/24/2008).  Though Drake confidently asserts the […]
