Astrographic Catalogue Project (USNO) - http://ad.usno.navy.mil/ac/ac.html

The Astrographic Catalogue (AC) was an international effort designed to photograph and measure the positions of all stars brighter than magnitude 11.0. In total, over 4.6 million stars were observed, many as faint as 13th magnitude. This project was started over 100 years ago. The sky was divided among 20 observatories, by declination zones. Each observatory exposed and measured the plates of its zone, subsequently publishing the plate measures.
The U.S. Naval Observatory has completed data entry of the printed volumes of the AC, has completed the data reduction of each zone, and has converted the positions to the system defined by Hipparcos. The resulting catalog, called AC 2000, is now available.

Astronomical Software & Documentation Service (ASDS) - http://asds.stsci.edu/

The Astronomical Software and Documentation Service (ASDS) is a network service that allows you to find existing astronomical resources for solving your problem. ASDS started life as the Astronomical Software and Documentation Service, devoted entirely to astronomical software packages and their associated on-line documentation. Much code is rewritten these days, not because anyone has found a fundamentally better way to solve the problem, but because they simply don't know who has already done it, whether the code runs on the system they have available, or where to get it if it does. That is the problem that ASDS was intended to solve. The objectives of ASDS changed in 1998 when its scope was expanded to include astronomical observing sites and their associated telescope and instrument manuals, taken from a listing maintained by Liz Bryson (bryson@cfht.hawaii.edu). The service was renamed at this point.

International Conference on "The Cosmological Constant and the Evolution of the Universe", The University of Tokyo (Tokyo, Japan), November 7 - 10, 1995
Observational data, such as the Hubble constant measurements and estimates of the age of globular clusters, have strongly suggested the existence of nonvanishing cosmological constant. It is, however, quite difficult to explain the observationally suggested value on purely theoretical grounds. The purpose of the Conference was to bring together the observational data and theoretical ideas concerning the cosmological constant.

Darwin (Space IR Interferometry Mission) - http://ast.star.rl.ac.uk/darwin/

Darwin is a proposal for a European infrared interferometer in space. Its first aim is to detect Earth-like planets around nearby stars, and then to search for a signature of life, ozone in an atmosphere. It could also be used as a general-purpose infrared observatory.
Darwin was proposed to the European Space Agency (ESA) for a Cornerstone Mission in its Horizon 2000 Plus plan. In October 1995, ESA decided to study such an infrared interferometer as an option for its Interferometer Cornerstone. The Darwin and Edison teams have combined to promote the selection by ESA of this option. The Darwin advocacy team members are also members of the International Working Group on Space Interferometry , a pressure group for this type of mission. Final selection on cost, science and technology grounds will be made around 2000, for a launch in the period 2009 - 2017.

As target for neutrino capture, a large amount (30 tons) of the rare element Gallium in form of an aqueous solution of Galliumtrichloride was used. To protect the detector from the interfering cosmic radiation one must go deep underground. Hence the experiment was carried out under the shielding of Italy's highest mountain outside the Alps, the Gran Sasso d'Italia in the Abruzzo region.

Gravity Probe B Relativity Mission (Stanford) - http://einstein.stanford.edu

Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity. The experiment will check, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at 400-mile altitude directly over the poles. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe.

Green Flashes (An Introduction) - http://mintaka.sdsu.edu/GF/

Green flashes are real (not illusory) phenomena seen at sunrise and sunset, when some part of the Sun suddenly changes color (at sunset, from red or orange to green or blue). The word ``flash'' refers to the sudden appearance and brief duration of this green color, which usually lasts only a second or two at moderate latitudes.

Hubble Deep Field (HDF) - http://www.stsci.edu/ftp/science/hdf/hdf.html

The Hubble Deep Field (HDF) is a Director's Discretionary program on HST in Cycle 5 to image a typical field at high galactic latitude in four wavelength passbands as deeply as reasonably possible. In order to optimize observing in the time available, a field in the northern continuous viewing zone (CVZ) was selected and images were taken for 10 consecutive days, or approximately 150 orbits. Shorter 1-orbit images were also obtained of the fields immediately adjacent to the primary HDF in order to facilitate spectroscopic follow-up by ground-based telescopes. The observations were carried out from 18-30 December 1995, and the data are available to the community for study.

Hubble Space Telescope Astrometry Science Team - http://clyde.as.utexas.edu/

See how astrometry, one of the oldest branches of astronomy, uses the Hubble Space Telescope, one of the newest tools of astronomy. Interrogate our home page to find out what we do, who we are, and what we've done. Look over our shoulder as we search for planets around a nearby star. We use the Fine Guidance Sensors aboard the Hubble Space Telescope (HST) to measure star positions, study binary stars and study stellar motions. Primarily, stellar positions yield parallaxes which provide information on distance. The distances to nearby stars calibrate the entire astronomical distance scale. Monitoring star position may reveal previously unseen companions. We search for planets near Proxima Centauri and Barnard's Star. We also work to tie the HIPPARCOS reference frame to an extragalactic (non-rotating) reference frame. We study binary stars unresolvable using ground-based techniques. We inspect stars to determine whether or not they are binary. We use the Planetary Camera to obtain images of stars in globular clusters. The precision with which we can measure positions is so high, that after 3-5 years a second image will show motions of stars in clusters 6 kpc distant.

IAAT (Astronomy): Time Series Analysis - http://astro.uni-tuebingen.de/groups/time/

This is the homepage of the time series analysis group at the Institute for Astronomy and Astrophysics, Sect. Astronomy, in Tübingen (Germany).
We are dealing with problems of the deterministic (periodic) and non-deterministic behavior of astronomical time series measured by X-ray satellites. The object of our work is to develop tools both for analysing and simulating time series in order to improve the understanding of the time dependent processes taking place in the objects observed by satellites (EXOSAT, Ginga, ROSAT, XTE, ASCA).
