PASADENA—Astronomers have discovered 16 new extremely distant quasars, the result of a search made nearly 40 times more efficient than previously possible by applying artificial intelligence to the new Palomar digital sky survey. This novel technique allows researchers to study more easily the formation of quasars and large-scale structures in the early universe.
"This is one of the first successful major applications of artificial intelligence techniques in astronomy and space science," said Usama Fayyad, a scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, California.

PASADENA—Astronomers at the California Institute of Technology and the Johns Hopkins University today announce the discovery of what they believe is a brown dwarf, and release the first image and spectrum ever taken of this elusive type of object.
The brown dwarf, called GL 229B, lies in the southern-hemisphere constellation Lepus, near Orion, where it orbits a small, dim star called GL 229. This is the first detection of such a cool object outside the solar system.

PASADENA—Caltech Professor of Physics Harvey Newman and his collaborators on the MARKJ physics project shared a special prize in July from the European Physical Society with three other research groups "for establishing the existence of the gluon."
Gluons are the fundamental packets of energy that bind together quarks—the fundamental building blocks of matter—to form more complex particles such as pions and kaons, and the protons and neutrons that make up the core of every atom.

PASADENA—Peter M. Goldreich, the Lee A. DuBridge Professor of Astrophysics and Planetary Physics at Caltech, will receive the 1995 National Medal of Science from President Clinton at a White House ceremony on October 18.
In a statement released today, the White House announced the eight names of this year's winners of the National Medal of Science, which is awarded periodically in special recognition of outstanding scientific contributions. Goldreich is the nineteenth member of the Caltech faculty to be honored with this award.

Astronomers have discovered direct evidence that most quasars came into existence during the same era, when the universe was still in its infancy. This discovery will help scientists use quasars, the most luminous objects in the sky, as tools for studying the universe back to a time when it was less than a billion years old.

PASADENA—Caltech astronomers have counted galaxies to a limit of about 24th magnitude, the faintest ever counted in infrared light. Observing five small patches of sky with the 10-meter telescope at the W. M. Keck Observatory in Hawaii, the scientists found that the numbers of galaxies continued to rise with increasing faintness, a result that agrees well with models in which the universe is "open" and will continue to expand forever.
