Wishing ET Upon a Star
July 19, 2010
What are the odds of finding extraterrestrials?  That subject has been discussed ad infinitum, but David Shiga at New Scientist thinks the odds just went up.  “Solitary suns like ours are not as rare as we once thought, boosting the likelihood that there are other life-friendly solar systems in the universe.”  It should be noted […]

Using Aliens to Titillate the Public
June 28, 2010
Geologists cannot even figure out our own planet (next headline), but some of them claim to know a lot about other planets – their geological history, and even their prospects for life.  Is it fair to tease the public with the L-word life when so much remains to be understood on the ground under our […]

Are There Limits to Scientific Speculation?  A Royal Case
May 2, 2010
Question: When does science become like a priesthood?  Answer: When its practitioners engage in speculation on big questions impossible to verify with empirical observations.  Is this what the chief astronomer in Britain is doing?     Sir Martin Rees certainly would not have thought of himself as a priest as he wrote an article for […]

Cosmologist Suffers Paranoid Delusions: Media Promotes His Views
April 26, 2010
“They’re coming to get us, and I’m sure of it, because I know everything.”  What would you think of someone who talked like that?  What if he were one of the most famous cosmologists alive today?  The man is Stephen Hawking – that wheelchair-bound math wizard who talks with a speech synthesizer and once fell […]

SETI and other Pointless Gimmicks
April 15, 2010
Astrobiologist Paul Davies sure knows how to ask interesting questions, and ruffle feathers in the process.  His new book about SETI, The Eerie Silence, reviewed by Leslie Mullen in Astrobiology Magazine, defaced some long-standing notions.  But are his suggestions any improvement?     Davies thinks the Voyager record was a “pointless gimmick.”  He thinks that […]

Search for Intraterrestrial Life Scores Big
March 16, 2010
Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance.  Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere.     PhysOrg reported that half of the world’s life may lie […]

Who Should Be Listening to Scientists?
February 17, 2010
“Stop Listening to Scientists?” is an unusual title for a letter to Science.1  In a commentary last week prompted by the recent scandals regarding climate change, Kevin Robert Gurney (Purdue) made a shocking exclamation: don’t listen to scientists.  Here’s how he began. As a climate scientist and a contributing author to the Intergovernmental Panel on […]

SETI, Miracles, and Comfort
February 1, 2010
Would knowledge that the universe is filled with aliens bring you comfort?  Or are you more comfortable thinking humans are alone in the universe?  Seth Shostak, director of the SETI Institute, was interviewed briefly by Bill Hemmer on Fox News this morning, where only one answer to this idea was assumed.     Shostak came […]

Aliens Invade Science News
January 25, 2010
What are aliens doing in science news reports?  There is no evidence they even exist.  That has not hindered some scientists from speculating.  BBC News reporters Pallab Ghosh headlined an entry “Astronomers hopeful of detecting extra-terrestrial life,” and adorned it with a Hollywood-style alien corpse.  The article highlighted the optimism of Lord Rees, the president […]

Fermi Paradox Reasserts Itself
January 23, 2010
Paul Davies, no stranger to facing difficult questions and proposing imaginative solutions, is coming out with a new book in April about SETI.  In it, he tackles the Fermi Paradox: if aliens are out there, why haven’t they dropped by yet?  Amazon.com lists some of the ideas to be presented in The Eerie Silence: Renewing […]

SETI Will Turn 50 in 2010
December 31, 2009
There hasn’t been much news about SETI lately, but expect more in the coming year.  In April 1960, 50 years ago, Frank Drake began the first SETI search with radio telescopes called Project Ozma (see SETI Institute description).  No undeniable signal of intelligent origin was found that year or in the 50 years since, despite […]

Is SETI Morphing Its Mission?
November 29, 2009
Look at the mission statement at the website of the SETI Institute: “The mission of the SETI Institute is to explore, understand and explain the origin, nature, and prevalence of life in the universe.”  What happened to the aliens?  The word “intelligence” is not found in their mission statement.  It sounds indistinguishable from the mission […]

Can SETI Be Quantified?
October 31, 2009
What is the probability of finding intelligent life on other planets?  In 1960, Frank Drake attempted to quantify that question with his famous Drake Equation (see MSNBC and NOVA, which allows you to estimate the probability with an interactive meter).  Trouble is, Stanley Miller and Leslie Orgel of primordial soup fame thought it was meaningless.  […]

Twitter the ET Bandwidth Wagon
August 16, 2009
If you have nothing better to do, send a message to an alien.  Leonard David reported on Space.com that a website in Australia is collecting messages to beam up to a planet named Gliese 581d that is 20.3 light-years away.  Even a Senator who is Australia’s Minister for Innovation, Industry, Science and Research got involved.  […]

Aliens Are Not Bodybuilders
July 16, 2009
Seth Shostak of the SETI Institute is willing to bet “dollars to Devil Dogs that any extraterrestrials we detect won’t be muscular guys with deep voices and corrugated foreheads, or even big-eyed, hairless grays.”  It all has to do with the way evolution works.     In the weekly SETI column for Space.com, Shostak opined […]
