COLUMBIA LOST
The space shuttle Columbia disintegrated in flames over Texas yesterday
just 16 minutes from home. All seven astronauts - six Americans and an Israeli
- died as the shuttle broke apart, traveling 39 miles above the Earth at
12,500 m.p.h., and rained debris over hundreds of miles of countryside.

Confirmation of the Big Bang. Hugh Ross explains the latest discovering of polarized light confirming the Big Bang. Audio at http://www.oneplace.com/ministries/creation_update/ also see Cosmic Microwave Background Radiation's Polarization Detected at Last: Although it was discovered less than 40 years ago, the cosmic microwave background (CMB) radiation has been around a lot longer than that. A relic from the early days of the Universe more than 14 billion years ago, the CMB is the oldest radiation on record. Current cosmological models posit that the CMB should be slightly polarized but this property has never been observed--until now.
Speed Of Gravity Measured: Charlottesville - Jan 09, 2003 - Taking advantage of a rare cosmic alignment, scientists have made the first measurement of the speed at which the force of gravity propagates, giving a numerical value to one of the last unmeasured fundamental constants of physics.

On January 2nd 2004 the NASA space mission, Stardust, will fly through comet
Wild 2, capturing interstellar particles and dust and returning them to
Earth in 2006. Space scientists from the Open University and University
of Kent have developed one of the instruments which will help tell us more
about comets and the evolution of our own solar system and, critical for
Stardust, its survival in the close fly-by of the comet.

Has ESA's
Xmm-Newton Cast Doubt Over Dark Energy? Paris - Dec 17, 2003
ESA's X-ray observatory, XMM-Newton, has returned tantalising new data about
the nature of the Universe. In a survey of distant clusters of galaxies,
XMM-Newton has found puzzling differences between today's clusters of galaxies
and those present in the Universe around seven thousand million years ago.
Some scientists claim that this can be interpreted to mean that the 'dark
energy' which most astronomers now believe dominates the Universe simply
does not exist?

Rings Around
The Planets: Recycling Of Material May Extend Ring Lifetimes. Boulder
- Dec 09, 2003
Although rings around planets like Jupiter, Saturn, Uranus and Neptune are
relatively short-lived, new evidence implies that the recycling of orbiting
debris can lengthen the lifetime of such rings, according to University
of Colorado researchers.
Planet-formation
Model Indicates Earthlike Planets Might Be Common.
Astrobiologists disagree about whether advanced life is common or rare in
our universe. But new research suggests that one thing is pretty certain
if an Earthlike world with significant water is needed for advanced
life to evolve, there could be many candidates. In 44 computer simulations
of planet formation near a sun, astronomers found that each simulation produced
one to four Earthlike planets, including 11 so-called "habitable"
planets about the same distance from their stars as Earth is from our sun.
Interstellar
Hydrogen Shadow Observed For The First Time. San Francisco - Dec 09,

using data gathered by CAPS, destined to reach Saturn in July 2004.
The Big Crunch.
Moffett Field - Dec 09, 2003
Cosmologists model the end of the universe as The Big Crunch-they roughly
reverse the simulations of how the expansive Big Bang might have spawned
all the stars and planets. But for those interested in what is happening
between the bang and the crunch on those uncountable number of planets,
the big crunch can mean something different.
Trail
Of Black Holes And Neutron Stars Points To Ancient Collision.
An image of an elliptical galaxy by NASA's Chandra X-ray Observatory has
revealed a trail of black holes and neutron stars stretching more than fifty
thousand light years across space. The trail of intense X-ray sources is
evidence that this apparently sedate galaxy collided with another galaxy
a few billion years ago.

In this topsy-turvy world of changing trends and stormy alliances, two Northeastern
University scientists propose an answer to why even the fundamental constants
of nature don't seem constant anymore. The bond between electrons and protons,
called the fine structure constant, or alpha, may not be constant and may
have been 200,000 times weaker about ten billion years ago.

Research with the Solar and Heliospheric Observatory (SOHO) spacecraft has
revealed the process that may implement the reversal in the direction of
the Sun's magnetic field that is known to occur every 11 years. This newly
recognized factor in the Sun's magnetic flipping is the cumulative effect
of more than a thousand huge eruptions called Coronal Mass Ejections (CMEs).
(Note that Kent Hovind does not believe a magnetic field can reverse especially
on earth)
Is The
Sun An Iron-Rich Powerhouse. Rolla - Nov 18, 2003
The spate of solar storms to hit Earth in recent days may be caused by the

Despite evidence from two space probes in the 1990s, radar astronomers say
they can find no signs of thick ice at the moon's poles. If there is water
at the lunar poles, the researchers say, it is widely scattered and permanently
frozen inside the dust layers, something akin to terrestrial permafrost.

Age
of the Universe:
"Astronomers have just developed and applied another independent tool

age of 13.7 billion years. This finding adds further confirmation to the
idea that the expansion rate of the universe is controlled by multiple factors,
and corroborates the big bang model, which is consistent with
the biblical account that a transcendent Creator is responsible for the
creation of the universe." (Reasons

of lithium, containing none of the elements necessary for life as we know
it. From those primordial gases were born giant stars 200 times as massive
as the sun, burning their fuel at such a prodigious rate that they lived
for only about 3 million years before exploding. Those explosions in turn
spewed elements like carbon, oxygen and iron into the void at tremendous
speeds.

"Iron-Clad"
Evidence For Spinning Black Hole. Boston - Sep 17, 2003
Telltale X-rays from iron may reveal if black holes are spinning or not,
according to astronomers using NASA's Chandra X-ray Observatory and the
European Space Agency's XMM-Newton Observatory. The gas flows and bizarre
gravitational effects observed near stellar black holes are similar to those
seen around supermassive black holes. Stellar black holes, in effect, are
convenient 'scale models' of their much larger cousins.

Astrophysicists
Discover Massive Forming Galaxies. LIVERMORE, Calif.
A Lawrence Livermore National Laboratory astrophysicist, in collaboration
with international researchers, has found evidence for the synchronous formation
of massive, luminous elliptical galaxies in young galaxy clusters.The forming
galaxies were detected at sub-millimeter wavelengths. Emission at these
wavelengths is due to dust from young stars that is heated by the stars
or by active black holes. The galaxies were grouped around high-red shift
radio galaxies, the most massive systems known, suggesting that they all
formed at approximately the same time.
Was
The Universe Born In A Black Hole?
The universe may have been created by an explosion within a black hole,
according to a new theory by two mathematicians recently published in the
Proceedings of the National Academy of Sciences of the U.S.A. In the new
model, the Big Bang is an actual explosion within a black hole in an existing
space. The shock wave of the explosion is expanding into an infinite space,
leaving behind it a finite amount of matter. The universe is emerging from
a white hole. The opposite of a black hole, a white hole throws matter out
instead of sucking it in.

Galactic
dust storm enters Solar System
New data suggests the Sun's shifting magnetic field is set to focus a decade-long
storm on the inner Solar System, including Earth. During the last decade,
the magnetic field of the Sun acted like a shield, deflecting the electrically
charged galactic dust away from the Solar System. However, the Sun's regular
cycle of activity peaked in 2001. As expected, its magnetic field then flipped
over, so that south became north and vice-versa. In this configuration,
rather than deflecting the galactic dust, the magnetic field should actually
channel the dust inwards. This pattern may have been repeated during previous
solar cycles but it is only now that astronomers are beginning to have the
data they need to prove it. See

The Galactic Odd Couple. The two most powerful phenomena in galaxies are active galactic nuclei (AGNs) and starbursts. The former are intense, concentrated sources of lightprobably matter falling into a supermassive black hole. Starbursts are galactic fireworks shows during which stars form at a frenetic pace.
