Advanced press release search

8 January 2001: The National Optical Astronomy Observatory's Deep Wide-Field Survey marks its first release of data today with a large, exhibit-sized image of 300,000 faint galaxies and stars at the opening of the 197th meeting of the American Astronomical Society.

14 November 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.

25 March 1999: Astronomers using the National Science Foundation's (NSF) Kitt Peak National Observatory (KPNO), near Tucson, Arizona, contributed important optical observations of a Gamma-Ray Burst (GRB) discovered on 23 January 1999. The KPNO observations of this particularly powerful and well-observed GRB are included in articles appearing in current issues of the journals Science and Nature. This event was the first GRB detected simultaneously at optical and gamma-ray wavelengths, and may provide the first clear evidence that GRBs emit a stream, or jet, of photons directed out into space like a searchlight.

6 January 1999: Astronomers George H. Jacoby and Taft E. Armandroff of the National Optical Astronomy Observatories in Tucson, Arizona, and James E. Davies of The Johns Hopkins University announced today their discovery of a new galaxy in The Local Group, the group of galaxies within 4 million light-years of our own Milky Way. The new galaxy is the second one that the team has found in the past year by using new computer enhancement techniques applied to 10-year old photographs of the sky. Small galaxies of the type found by Jacoby and collaborators are the most common type of galaxy in the universe, yet the region around the Milky Way Galaxy's big brother, the spiral galaxy in Andromeda, had been thought to be highly deficient of these "dwarf" galaxies before the team began their search. The census of the Local Group, though, is now as high as 43 galaxies, meaning that our neighborhood may not be as unusual as was previously thought.

17 June 1998: Samuel Barden, National Optical Astronomy Observatories (NOAO) , has been awarded the 1998 Maria and Eric Muhlmann Award of the Astronomical Society of the Pacific . The Muhlmann Award is given for innovative advances in astronomical instrumentation, software, or observational infrastructure that enable significant astronomical discoveries. The award to Dr. Barden recognizes his pioneering use of optical fibers with astronomical spectrometers.
