Press Releases 2000

14 Noviembre 2000: Astronomers studying how elements heavier than iron were produced in the early Milky Way have identified a distinct series of epochs of galaxy-wide chemical formation.

16 Octubre 2000: The first scientific observations from the Gemini North telescope provide a dramatic glimpse into the elusive core of the Milky Way, including an intriguing bow-shock from a star as it plows into a poorly understood gas cloud a mere 3 light-years from the galactic center.

30 Marzo 2000: Astronomers from the National Science Foundation's National Solar Observatory are announcing in today's issue of Science that their discovery of periodically varying gas motions below the solar surface provides an important clue toward solving the biggest secret of the Sun - the origin of the 11-year cycle of solar activity.

20 Marzo 2000: After traveling in the shadow of the Eiffel Tower, through the Panama Canal and up a steep, narrow mountain road to a remote peak in Chile, one of the world's largest astronomical telescope mirrors arrived safely at the Gemini South Observatory on March 17th, 2000. The mirror, which can collect more light than two million human eyes, is the heart of the Gemini South Telescope on Cerro Pachón, a mountain in central Chile. The telescope will soon join its identical twin, on Hawaii's Mauna Kea, to provide extremely high-resolution images of the universe.

13 Enero 2000: Astronomers, high school teachers and their students have discovered 73 novae in the Andromeda galaxy through a National Science Foundation (NSF) funded education program called "The Use of Astronomy in Research Based Science Education" (RBSE). These results will be presented today by Dr. Travis A. Rector and George H. Jacoby of the National Optical Astronomy Observatory (NOAO), in Tucson, AZ, to the American Astronomical Society meeting in Atlanta, GA. Novae are stellar outbursts that lead to a rapid brightening when mass is transferred between two stars in a binary system, causing the surface layers of one star to ignite explosively from the fusion of hydrogen nuclei.
