Galaxy-Spangled Banner Unfurled

The Hubble team has unveiled a new deep field image of distant galaxies, the “Hubble Ultra Deep Field Infrared WFC3/IR.”  The image, available at the HubbleSite, was taken with the new Wide Field Camera 3 (WFC3) installed during the latest servicing mission.     It’s been 5 years since the Hubble Ultra Deep Field (03/09/2004; […]

Is the Universe Evolving Upward?

It’s intuitively obvious that to get from a big bang to intelligent astronomers looking for evidence of the bang through telescopes, the amount of organization in the universe must increase over time dramatically.  Lately, astronomy has uncovered much more dynamism in space than previously recognized – but much of it seems destructive, not creative. Orion […]

Cosmic Accounting Is Wildly Inaccurate

Counting faint celestial objects is admittedly hard, but the task should be within the capabilities of expert astronomers.  It is, after all, as simple as counting.  So much theoretical work relies on accurate counts of what’s out there, they need to get at least in the ballpark.  Recent indications hint that their counts have been […]

Early Large Galaxies Stun Cosmologists

Cosmology has a kind of Cambrian Explosion of its own to grapple with.  Contrary to expectations, some of the earliest galaxies appear as large as current ones, if not larger.  Astronomers, using the Subaru telescope in Hawaii, examined five galaxy clusters with ages estimated at 5 billion years after the Big Bang.  Statements in a […]

Star Children for Darwin

Why should we be looking for alien intelligence around other stars when it is right behind your eyeballs?  You may not have known that you are a star child, but that’s what a leading astronomer called you.  As a good star child, you need to pay tribute to Charles Darwin.     In New Scientist, […]

Dating Stars as Models

Many have dreamed of dating a star, but the way astronomers do it is less glamorous.  For one thing, they need to know how old she is first, and how good a model she makes.  In a Perspectives piece for Science,1 David R. Soderblom of the Space Telescope Science Institute explained the requirements for stellar […]

2009 Is Looking Up

Astronomy is looking up this year; in fact, it’s looking heavenly.  The United Nations and the International Astronomical Union have designated 2009 the International Year of Astronomy (IYA2009).  The IYA2009 website explains, The International Year of Astronomy (IYA2009) will be a global celebration of astronomy and its contributions to society and culture, highlighted by the […]
