Press Releases: NOAO

15 Febrero 2001: Catherine (Caty) Pilachowski, a scientific staff member at the National Optical Astronomy Observatory in Tucson, AZ, has been elected as the new president of the American Astronomical Society.

11 Enero 2001: A sharply detailed image of the northwest portion of the Andromeda galaxy, M31, demonstrates the power of an on-going sky survey project sponsored by the National Optical Astronomy Observatory (NOAO).

9 Enero 2001: Astronomers surveying hundreds of red giant stars in more than a dozen globular star clusters have found clues that may reveal an unexpected origin of lithium, the third element in the Periodic Table.

8 Enero 2001: The simple spherical geometry of planetary nebula Abell 39 will help astronomers identify the source of very serious errors in measuring the chemical composition of dying stars.

8 Enero 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 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.

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.

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.

21 Septiembre 1999: Students in Susie Townsend's multi-age classroom at Miles Exploratory Learning Center, 1400 E. Broadway Blvd., will work with local astronomers and noted authors Joni Chancer and Gina Rester-Zodrow this Friday, September 24, at 10:00 am. Students will safely observe the Sun and then interpret their observations through art and writing invitations. Townsend's class will be studying the Sun and its impact on Earth throughout the school year using a multi-disciplinary, inquiry approach to learning. The Sun is entering the peak of an 11-year cycle of activity, making this a particularly exciting time to investigate solar behavior.

30 Julio 1999: The National Optical Astronomy Observatories (NOAO) is a partner in a multi-institutional center involved in the rapidly developing field of adaptive optics, which promises to revolutionize astronomy and vision science.

25 Junio 1999: At a ceremony in Hawaii today, astronomers revealed some of the sharpest infrared images ever obtained by a ground-based telescope. These first high-resolution images from the new Gemini North Observatory show the remarkable power of the telescope's technologies, which minimize distortions that have blurred astronomical images since Galileo first pointed a telescope skyward almost 400 years ago. The clarity of these images is equivalent to resolving the separation between a set of automobile headlights at a distance of 2,000 miles!

1 Junio 1999: Dr. Mark Giampapa of the National Science Foundation's National Solar Observatory in Tucson, Arizona, has determined that the Sun is in a relatively moderate state of activity. Giampapa's observations of Sun-like stars in M67 suggest that about 40% of the time the Sun is likely to be either significantly more, or significantly less, active. A change to either of these states is likely to cause significant changes in the Earth's climate. These same observations also indicate excursions in the luminosity of the Sun from about 0.2% - 0.5% are possible, compared with the 0.1% variations that have been measured with modern satellite instruments during the 1980s and 1990s. Any variation in what is considered typical or normal solar activity must be taken into account in the study of long-term behavior of the global climate.

31 Mayo 1999: Dr. Samuel Barden, astronomer at the National Science Foundation's National Optical Astronomy Observatories in Tucson, Arizona, has partnered with Mr. Willis Colburn and Mr. James Arns at Kaiser Optical Systems, Inc. (KOSI), Ann Arbor, Michigan for the development of large format spectroscopic gratings using holographic technology for astronomical applications funded by the National Science Foundation through the Advanced Technologies and Instrumentation Program in the division of Astronomy. These new technology gratings can provide information at multiple regions of the spectrum simultaneously, with higher efficiency, less cost, and greater durability than the conventional grating technology that astronomers have relied on for over a hundred years.

31 Mayo 1999: Dr. John W. (Jack) Harvey, astronomer at the National Science Foundations National Solar Observatory (NSO) at Kitt Peak, Arizona, has been awarded the prestigious George Ellery Hale Prize by the American Astronomical Society in recognition of his "outstanding contributions to the field of solar astronomy over an extended period of time".

31 Mayo 1999: The National Science Foundation's National Solar Observatory is preparing for the upcoming solar maximum with SOLIS, a new suite of ground-based solar telescopes that will increase our understanding of solar activity and its effect on Earth's climate and atmosphere.

31 Mayo 1999: The Sun is known to exhibit a maximum of activity, including solar flares and an increased number of sunspots and coronal mass ejections, approximately every 11 years. Dr. Richard C. Altrock announces today his prediction that the next solar maximum will occur between January and April of 2000 based on a new method employing daily observations of high latitude coronal activity. Dr. Altrock, an Air Force Research Laboratory astronomer at the National Science Foundation's National Solar Observatory (NSO) at Sacramento Peak, New Mexico, will present his result today to the American Astronomical Society meeting in Chicago, Illinois. This prediction is of interest to solar astronomers and others who design and operate satellites.

25 Marzo 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 Enero 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 Diciembre 1998: The discovery of the acceleration of the universe by two teams of astronomers using the National Science Foundation's (NSF) National Optical Astronomy Observatories (NOAO) was named by the journal Science as the top scientific research advance of 1998.

24 Septiembre 1998: October of 1998 marks the 40th anniversary of the founding of Kitt Peak National Observatory (KPNO), the first astronomy observatory in the U.S. available to all qualified astronomers regardless of institutional affiliation. Kitt Peak today is home to the world's largest collection of optical telescopes, under skies which continue to be some of the finest in the world for astronomical observations. Historical images and information on the excellence of scientific research at Kitt Peak can be found through a link on the KPNO Home Page at http://www.noao.edu/kpno/40th/.
