Mature
Galaxies in Young Universe At Odds with Theory
The discovery of massive galaxies in the infant universe has astrophysicists
puzzling over how such objects could have formed so early on. The leading

slowly develop. The new find may force scientists to reexamine how stars
arise.

How Mars got its
rust
The intense heat inside the early Earth was enough to convert a lot of iron
oxide into molten metallic iron, which seeped down into the planet to form
a huge liquid core. Mars never achieved the temperatures needed for this
process simply because it is smaller, they say. This left more iron oxide
in the upper layers of the planet, which led to its distinctive russet hue
and relatively puny iron core.

A New
Moon for Earth? March 26, 2004
Earth has acquired a "quasi-moon" an asteroid that will
encircle our planet for the next couple of years while it orbits the sun
on a horseshoe-shaped path, according to a report to be published on Saturday
in New Scientist. The asteroid, 2003 YN17, "is probably a chunk of
debris" from an impact between a larger space rock and the surface
of the moon, the British weekly said.

the tiny mineral spheres that litter the rover's landing site. The question
was a key one, because hematite almost always forms in water, and water
is thought to be a pre-requisite for life.

THE GHOST IN THE COSMOS
The universe is riddled with inexplicable forces. Something strange is tearing
space apart. Something unknown holds spinning galaxies together. And at

call these three somethings dark energy, dark matter and inflation, and
to a large extent they are all abiding mysteries. But recently, while exploring
Einsteins equations of relativity, a group of physicists noticed something
peculiar: all three forces could be one and the same. Their theory claims
they all stem from one omnipresent fluid called the ghost condensate. See
latest issue of the New Scientist.

Four
Keys to Cosmology
In what is widely regarded as the most important scientific discovery of
1998, researchers turned their telescopes to measure the rate at which cosmic
expansion was decelerating and instead saw that it was accelerating. They
have been gripping the steering wheel very tightly ever since. As deeply
mysterious as acceleration is, if you just accept it without trying to fathom
its cause, it solves all kinds of problems. Before 1998, cosmologists had
been troubled by discrepancies in the age, density and clumpiness of the
universe. Acceleration made everything click together. It is one of the
conceptual keys, along with other high-precision observations and innovative
theories, that have unlocked the next level of the big bang theory.

NASA officials at the Jet Propulsion Laboratory have confirmed that the
Mars Exploration Rover Spirit has responded to an emergency command this
morning by sending back a radio beep -- an event which had been stated as
a possibility, but not a certainty, at the end of this morning's JPL press
conference. "This means it's commandable," a JPL spokeswoman told
SpaceDaily. The command was tailored to the assumption that the rover's
onboard computer is currently in a "fault mode", and the beep
confirms that it has detected a serious fault, either in the hardware or
the software. The fact that the rover responded at all, however, is encouraging.
(this file will be updated until the rover is fully recovered).

that might be orbited by habitable planets. Starting in 2015, NASA's Terrestrial
Planet Finder (TPF) will look at the top 30 stars from her list.

Makes Great Catch..Heads for Touchdown. Pasadena - Jan 05, 2004
Team Stardust, NASA's first dedicated sample return mission to a comet,
passed a huge milestone Friday by successfully navigating through the particle
and gas-laden coma around comet Wild 2 (pronounced "Vilt-2").
Movie Offers
Insights In To Workings of Mysterious Microquasars. Socorro - Jan 07,
2004
Astronomers have made a 42-day movie showing unprecedented detail of the
inner workings of a strange star system that has puzzled scientists for
more than two decades. Their work is providing new insights that are changing
scientists' understanding of the enigmatic stellar pairs known as microquasars.
Suns Of All
Ages Possess Comets, Maybe Planets. Atlanta - Jan 07, 2004
In early 2003, Comet Kudo-Fujikawa (C/2002 X5) zipped past the Sun at a
distance half that of Mercury's orbit. Astronomers Matthew Povich and John
Raymond (Harvard-Smithsonian Center for Astrophysics) and colleagues studied
Kudo-Fujikawa during its close passage. Today at the 203rd meeting of the
American Astronomical Society in Atlanta, they announced that they observed
the comet puffing out huge amounts of carbon, one of the key elements for
life. The comet also emitted large amounts of water vapor as the Sun's heat
baked its outer surface.
Magnetars,
The Most Magnetic Stars Known, More Common Than Previously Thought.
Observations of explosions from an ultra-powerful magnetic neutron star
playing hide-and-seek with astronomers suggest that these exotic objects
called magnetars -- capable of stripping a credit card clean 100,000 miles
away -- are far more common than previously thought.

See Era Of Rapid Galaxy Formation; New Findings Pose A Challenge For Cold
Dark Matter Theory.
"The universe is always more complicated than our cosmological theories
would have it," says Nigel Sharp, program officer for extra-galactic
astronomy and cosmology at the National Science Foundation (NSF). Witness
a collection of new and recently announced discoveries that, taken together,
suggest a considerably more active and fastmoving epoch of galaxy formation
in the early universe than prevailing theories had called for.
Chandra
Locates Mother Lode Of Planetary Ore In Colliding Galaxies.
NASA's Chandra X-ray Observatory has discovered rich deposits of neon, magnesium,
and silicon in a pair of colliding galaxies known as The Antennae. When
the clouds in which these elements are present cool, an exceptionally high
number of stars with planets should form. These results may foreshadow the
fate of the Milky Way and its future collision with the Andromeda Galaxy.
Old
Equation May Shed New Light On Planet Formation.
New work with an old equation may help scientists calculate the thickness
of ice covering the oceans on Jupiter's moon Europa and ultimately provide
insight into planet formation. Planetary bodies, such as the Earth and its
moon, exert such gravitational force on one another that tides occur, not
just in the oceans, but also in bodies of the planets themselves. The surfaces
of planets actually rise and fall slightly as they orbit one another.

An
Odyssey of Mars Science: Part 2. Sacramento - Dec 30, 2003
The discovery by Mars Odyssey which has most captured the public's imagination
by far is the finding by its "GRS" experiment -- which includes
both gamma-ray and neutron spectrometers -- that Mars does indeed have a
massive reservoir of water ice near its surface in the polar regions writes
Bruce Moomaw.
Visual "Mirages"
Probe Distribution Of Dark Matter. Princeton - Dec 22, 2003
Sloan Digital Sky Survey scientists have discovered a gravitationally lensed
quasar with the largest separation ever recorded, and, contrary to expectations,
found that four of the most distant, most luminous quasars known are not
gravitationally lensed.
