- Mar 28, 2002 NASA SCIENTISTS CREATE AMINO ACIDS IN DEEP-SPACE-LIKE ENVIRONMENT. http://web99.arc.nasa.gov/~astrochem/aanature.html--NASA
scientists announced the creation of amino acids, critical for life, in
an environment that mimics deep space. The research will be published
in the March 28 issue of the journal Nature. In a laboratory at NASA
Ames Research Center in California's Silicon Valley, the team of
astrobiologists shone ultraviolet light on deep-space-like "ices,"
simulating conditions that are commonplace in interstellar space.
Deep-space ice is common water ice laced with simple molecules. The team
subsequently discovered amino acids, molecules present in, and
essential for, life on Earth. "This finding may shed light on the origin
of life itself," said Dr. Max Bernstein, the first author and chemist
at NASA Ames and the SETI Institute. "We found that amino acids can be
made in the dense interstellar clouds where planetary systems and stars
are made. Our experiments suggest that amino acids should be everywhere,
wherever there are stars and planets."
- March 21, 2002, OGLEing Possible New Planets, By
Alan M. MacRobert. For the first time, astronomers have discovered a
bunch of new extrasolar planets Ñ and perhaps other small, dark objects
as well Ñ by detecting the slight dimming they cause when passing across
the face of a star. The OGLE-III experiment monitored 5 million Milky
Way stars toward the galaxy's center for 32 nights. Andrzej Udalski
(Warsaw University Observatory) reports that out of this vast sample,
52,000 main-sequence stars roughly similar to the Sun met the study's
key criterion: their brightnesses were measured many times with high
(1.5 percent) precision. Of these stars, 46 clearly showed signs of
smaller objects transiting across their faces. And 43 displayed more
than one transit event, thereby revealing the companion object's orbital
period Ñ generally 1 to 6 days. http://SkyandTelescope.com/news/current/article_538_1.asp

- Dec 3, 2003. Hubble Makes Precise Measure of Extrasolar
World's True Mass -- http://oposite.stsci.edu/pubinfo/pr/2002/27/
-- An international team of astronomers used the Hubble Space
Telescope to help make a precise measurement of the mass of
a planet outside our solar system. The Hubble results show that
the planet is 1.89 to 2.4 times as massive as Jupiter, our solar
system's largest orbiting body. Previous estimates, about which
there are some uncertainties, place the planet's mass at a much
wider range: between 1.9 and 100 times that of Jupiter's. The
planet, called Gliese 876b, orbits the star Gliese 876. It is
only the second planet outside our solar system for which astronomers
have determined a precise mass.
- Dec. 19, 2001 -- NASA SCIENTIST FINDS SOME METEORITES NOT
SUGAR-FREE -- ftp://ftp.hq.nasa.gov/pub/pao/pressrel/2001/01-253.txt
-- A discovery by a NASA scientist of sugar and several related
organic compounds in two carbonaceous meteorites provides the
first evidence that another fundamental building block of life
on Earth may have come from outer space. A carbonaceous meteorite
contains carbon as one of its important constituents. Previously,
researchers had found in meteorites other organic, carbon-based
compounds that play major roles in life on Earth, such as amino
acids and carboxylic acids, but no sugars. RELEASE: 01-253
