More Hints at Early Origin of Stars, Galaxies

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 […]

Spiral Galaxies Wind Up Into Blurs In Short Cosmological Time

Cosmic billions of years received another challenge.  Sky and Telescope reported on a announcement by Michael R. Merrifield (University of Nottingham, England), Richard J. Rand and Sharon E. Meidt (University of New Mexico) in Monthly Notices of the Royal Astronomical Society that they measured the velocity of gases in the spiral galaxy, M77, and found […]

Big Bang Threatened by Axis of Evil

“We thought we knew all about the Big Bang – but a blip in the cosmic afterglow is threatening our ideas,” reported Marcus Chown in The Independent.  The “Axis of Evil” he speaks of is not North Korea and Iran, but a newly found polarity in the cosmic background radiation that is not explainable by […]

ID Film Takes Hollywood

Grauman’s Chinese Theater on Hollywood Boulevard is a top tourist attraction in Tinseltown.  It features dozens of handprints of famous movie and TV stars, from Lucille Ball and Bill Cosby to Mickey Mouse.  This venue of many a blockbuster and glitzy opening night seemed hardly a place for naturalistic cosmology to take a thrashing, but […]

Cosmologists Can’t Escape Conclusion of Design

Geoff Brumfiel of Nature1 decided to investigate the growing fracas over the anthropic principle (see 12/18/2005 entry); i.e., that our universe appears to be more than a coincidence.  In a piece called “Our universe: Outrageous fortune,” he looked at the views of Leonard Susskind and his few critics. For two decades now, theorists in the […]

Choose You This Day: Multiverse or I.D.

If Leonard Susskind is right, cosmologists are escaping the conclusion of intelligent design (ID) by backing into a radically speculative idea: a near infinity of universes.  Susskind, a theoretical physicist from Stanford, just published a book, Cosmic Landscape: String Theory and the Illusion of Intelligent Design (Little, Brown 2005), that explores current cosmological thinking about […]

SETI vs. Intelligent Design

Intelligent Design proponents have often pointed to the similarity between what they are doing and what SETI is doing.  For example, SETI is attempting to detect evidence of intelligence in coded signals from space, and design biologists are detecting evidence of intelligence in the DNA code.  Seth Shostak, Director of the SETI Institute, decided to […]

Grown Man in the Stellar Crib: Now What?

The cover of Science News has a strange cartoon explained on the inside in an article by Ron Cowen: Imagine peering into a nursery and seeing, among the cooing babies, a few that look like grown men.  That’s the startling situation that astronomers have stumbled upon as they’ve looked deep into space and thus back […]

Another Record Distant Galaxy Found

The Spitzer Space Telescope found a “positively gigantic” galaxy at a time the universe was supposedly only 800 million years old – just 5% the assumed age of the universe – according to a press release from Jet Propulsion Lab.  For the galaxy to be this big that far back, it must have “bulked up […]

Carl Sagan’s Cosmos Is Back

MSNBC News reported that Carl Sagan’s popular 13-part series Cosmos is returning to TV this week, digitally remastered and enhanced with new up-to-date animations.  The 1980 series, which began with its own Agnus Dei invocation “The cosmos is all that is, all that ever was, and all that ever will be,” went far beyond the […]

Cosmic Baby Boom Becomes Baby Explosion

There has been a trend in deep space astronomy to find more and more mature-looking stars and galaxies farther back in time (04/06/2005, 03/10/2005, 07/08/2005).  That trend just doubled or tripled.  An announcement in Nature1 (see press release by European Southern Observatory), a thousand galaxies were found at distances corresponding to estimated ages of 9 […]

Who Needs a Big Bang?

Noted in passing: there are astronomers who don’t accept the Big Bang theory.  Spaceflight Now had an article denying that the WMAP microwave data supports the big bang.  Also, a small but active Alternative Cosmology Group decries the “unjustified limiting of cosmological funding to work within the Big Bang framework.”  They held their meetings last […]

Can Atheism Breathe in an Anthropic Universe?

Astronomers Martin Rees and Mario Livio considered “Anthropic Reasoning” in a Science perspectives article.1  The question bears not only on SETI, and whether intelligent life exists elsewhere, but why it exists here.  They state the issue: We can imagine universes where the constants of physics and cosmology have different values.  Many such “counterfactual” universes would […]

Tailpipe Soot: Can It Live?

Better stay clear of polycyclic aromatic hydrocarbons (PAH).  They come out of your tailpipe and furnace, line your chimney, and generally are products of unhealthy processes like industrial waste and cigarette smoke.  According to Environment Canada, “PAHs are a concern because some of them can cause cancers in humans and are harmful to fish and […]

First-Generation Star Claim Discounted

e first generation of stars, made of pure hydrogen, might have been detected, are now shown to be erroneous (this is an update on the 04/24/2003 entry).  Iwamoto et al. in Science1 have shown that the two hyper-metal-poor stars are actually second-generation stars, seeded with heavy elements by supernovae.     Timothy C. Beers (Michigan […]
