  Press Release in English, June 30, 2005 - Astronomy 2006 - IAU XXVIth General Assembly
James E. Gunn, Eugene Higgins Professor of Astronomy at Princeton University, and a central and legendary figure in all three of the main areas of astronomy research -- theory, observation, and instrumentation -- has been selected by an international panel of experts to receive the 2005 Cosmology Prize of the Peter Gruber Foundation.
Gunn, 66, was born in Livingstone, Texas, and received a B.A. in Physics and Mathematics from Rice University and a Ph.D. in Astronomy and Physics from California Institute of Technology.
The recipient in 2001 was Sir Martin Rees, the Astronomer Royal of the United Kingdom and Royal Society Research Professor at Cambridge University.

Gunn's citation from the Royal Swedish Academy reads: "James Gunn first made theoretical contributions to the field of galaxy formation, the gaseous medium between galaxies and the presence of dark matter in galaxies.
Tremaine explained that Gunn started his career as a theoretical astronomer, doing groundbreaking work in gravitational lensing as a cosmological probe, the formation and evolution of galaxies and the large-scale structure of the Universe, and the physical nature of pulsars.
Gunn was a leader in the 1970's and 1980's in observational studies of distant galaxies, galaxy clusters, and quasars.

 Science Journal, Fall 1995, Research Rundown
Astronomers have discovered direct evidence that most quasars came into existence during the same era, when the universe was still in its infancy.
Astronomers first identified quasars in 1960 as starlike counterparts to strong sources of radio waves, but were initially unable to determine the nature of the objects.
Before this research, astronomers could measure only radio emissions from the lobes and were unable to distinguish the energy contribution of the relativistic electrons from that of the magnetic fields.

Indeed, last week, when astronomers analyzed the spectrum from the quasar they had found, they realized they were seeing light that had left its source at time when the universe was a baby, a mere infant of less than a billion years old.
When SDSS astronomer and Princeton graduate student Xiaohui Fan spotted the new quasar in the Sky Survey data he was studying based on observations made in March 2000, its distinctively red color showed it to be a likely candidate for a very distant quasar.
Indeed, said SDSS astronomer and Princeton researcher Robert Lupton, the new quasar is sure to attract more than its share of attention from astronomy groups at the biggest telescopes in the world.

 M100
The precise measurement of this distance allows astronomers to calculate that the universe is expanding at the rate of 80 km/sec per megaparsec (+/- 17 km/sec).
For example, a team of astronomers using the Canada-France-Hawaii telescope at Mauna Kea recently have arrived at a distance to another galaxy in Virgo that is similar to that found for M100 using HST -- but their result is tentative because it is based on only three Cepheids in crowded star fields.
To calculate accurately the Hubble Constant, astronomers must have two key numbers: the recession velocities of galaxies and their distances as estimated by one or more cosmic "mileposts," such as Cepheids.

The first came in the late 1920s from astronomer Edwin Hubble, who used the 100-inch telescope at Mount Wilson Observatory in Pasadena to measure the recession speeds of distant galaxies and concluded that the whole universe is expanding.
Some astronomers believe that many of the larger stars will continue their accretion of mass until precipitating the transformative phenomenon called a nova or supernova: a gigantic explosion which then scatters and redistributes the stuff of the former star in space.
The Danish astronomer Tycho Brahe did record a similar supernova phenomenon in 1572, which shook the foundations of the Aristotelian belief in the "perfection" of the heavens, and asecond was seen by his pupil Johannes Kepler in 1604.
