International Astrophysics Symposium to Honor Willy Fowler

PASADENA—An international symposium on nuclear astrophysics will be held in honor of the late Nobel laureate Willy Fowler, December 14 to 16 at Caltech.

Astronomers Announce Discovery of Extremely Distant Quasars

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.

Astronomers Announce Discovery of an Old Brown Dwarf

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.

Caltech Physicist Shares Prize from European Physical Society for Role in Finding Gluons

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.

Caltech Planetary Scientist Receives National Medal of Science

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.

Caltech Observatory Sees Start of New Solar Sunspot Cycle

The first sunspot in the new sunspot cycle was identified on Saturday, August 12, by astronomers at the California Institute of Technology's Big Bear Solar Observatory in Big Bear City, California.

Palomar Survey Reveals Peak in Quasar Formation

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.

Three Caltech Professors Elected to Fellowship in AAAS

PASADENA—Caltech faculty members Thomas Ahrens, Paul Jennings, and Anthony Readhead were recently elected to fellowship in the American Academy of Arts and Sciences, one of the oldest honor societies in North America.

Nobel Laureate William A. Fowler Dies at 83

William A. Fowler, who shared the 1983 Nobel Prize in physics for his research into the creation of chemical elements inside stars, died Tuesday morning, March 14, in Pasadena, California.

David Goodstein Named to Gilloon Professorship

PASADENA—David Goodstein, vice provost and professor of physics and applied physics, has been appointed the Frank J. Gilloon Distinguished Teaching and Service Professor. He is the first person to occupy this prestigious chair.
