AstroGLU is a discovery tool, to help locate database servers providing relevant information in the astronomical context related to a selected data type: object name, position on the sky, astronomer's name, etc.
AstroGLU is based on a dictionary of remote services, developed by CDS in the framework of the GLU system. It is the CDS contribution to the AstroBrowse project.
Astrographic Catalogue 2000 ( USNO )
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.
AstroGrid ( UK Virtual Observatory )
AstroGrid is a project aimed at building a data-grid for UK astronomy, which will form the UK contribution to a global Virtual Observatory.

AstroMB: Computer Aided Astronomy ( MBCAA )
The AstroMB software package provides a PC-based database, image viewer and planetarium to handle astronomical images and catalogs. Astronomical objects on images can be identified from catalogs. Observations at different energy range (e.g. X-ray and visible light) or at different times may be matched together. Astrometry and photometry can be performed automatically, with pattern recognition. The database holds the descriptions of many catalogs, such as radio sources, X-ray objets, minor planets, etc. It also holds the descriptions of more than 10,000 images, mainly from the ROSAT and Einstein Observatory satellites, and can be enriched with the user own data. The program is ASCOM compliant and can drive a telescope.
This is a mailing list for those interested in becoming an astronaut. The list is restricted to discussions of issues related to becoming an astronaut.

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 ( The service was renamed at this point.

The Canadian Space Geodesy Forum (CANSPACE) is a computer-communications-based information dissemination and discussion group that was established several years ago as an aid to improving communication among scientists and engineers working with the techniques of space geodesy. Among topics discussed are the Navstar Global Positioning System (GPS), Glonass, Transit, very long baseline interferometry, satellite laser ranging, satellite altimetry, etc. Daily postings of information bulletins include GPS satellite constellation status reports (Department of Defense Notice Advisories to Navstar Users) and reports of solar and geomagnetic field activity. Information concerning satellite launches and orbital elements is posted regularly. Although initially intended to link Canadian geodesists and geophysicists together, CANSPACE now has a wide international subscriber list and is open to all. Questions are particularly encouraged.

Darwin ( Space IR Interferometry Project )
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.

Disks, Planetesimals and Planets
Conference on Disks, Planetesimals and Planets, Puerto de la Cruz, Tenerife, SPAIN, 24-28 January 2000.
The recent discoveries of extrasolar planets and the progress in studies of disks around pre-main sequence and main sequence stars highlight the need of better understanding the formation and evolution of planetary systems. Many groups and observatories are dedicating important efforts towards these goals. The 1998 international time of the Canary Islands Observatories is fully devoted to studies related to these topics, making use of spectroscopic, polarimetric and photometric techniques in the optical, as well as near-IR photometry. The conference is the frame where the large amount of data collected with the facilities in the Canary Islands will be presented. In addition, contributions from participants addressing theoretical models and observations in all wavelength ranges will provide an updated overview of the field. The conference will last five days (including a free afternoon) and will consist of sessions with invited and contributed talks and poster. Sessions will devoted to: (a) PMS objects: circumstellar (protoplanetary) disks around protostellar objects, PMS stars and Vega-type stars (b) Planetesimals in PMS and MS stellar systems (c) Planets around stars (d) Searches for planets (e) Impact on planetary system studies of future space and ground-based facilities

The GALLEX experiment was performed by an international collaboration headed by MPIK Heidelberg. GALLEX measured the solar neutrino flux produced inside the Sun by proton-proton fusion. 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 )
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.

How to present rotation curves of Galaxies ? ( Galaxy Rotation Curves )
An alternative way to present astronomical data by combining atlas and catalog features: The Galaxy Wanted Poster. The Halpha and NII spectra of nearby spiral edge-on galaxies reveal next to their redshift velocities their individual kinetic fingerprints. Such velocity slices or rotation curves are correlated to the morphological properties of these objects. Based on a sample of 59 galaxies of the southern hemisphere a small rotation curve atlas has been compiled which allows fast comparison between visual and spectral observations.

Hubble Deep Field ( HDF )
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
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.

Hubble Space Telescope ( HST )
The Hubble Space Telescope is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) to operate a long-lived space-based observatory for the benefit of the international astronomical community. To accomplish this goal and protect the spacecraft against instrument and equipment failures, NASA had always planned on regular servicing missions. Hubble has special grapple fixtures, 76 handholds, and stabilized in all three axes. HST is a 2.4-meter reflecting telescope which was deployed in low-Earth orbit (600 kilometers) by the crew of the space shuttle Discovery (STS-31) on 25 April 1990. HST's current complement of science instruments include three cameras, two spectrographs, and fine guidance sensors (primarily used for astrometric observations). Because of HST's location above the Earth's atmosphere, these science instruments can produce high resolution images of astronomical objects. Ground-based telescopes can seldom provide resolution better than 1.0 arc-seconds, except momentarily under the very best observing conditions. HST's resolution is about 10 times better, or 0.1 arc-seconds.

This is done through formal programs such as regular colloquia, and informally through the common bond of fellowship in the Center. Space science, broadly defined as the study of the universe and our relationship to it, is simply too vast an area to be the province of a single discipline. Understanding the formation of the solar system is equally the task of the chemist who measures isotope effects in meteorites, the astronomer who observes planetary atmospheres or interstellar dust, and the theoretical physicist who studies gravitational collapse. Faculty and students of the Center thus belong to one of the basic, traditional science departments, yet overlap strongly in their research work.

Microlensing Planet Finder Project ( MPF, ex-GEST )
The Microlensing Planet Finder Project (MPF) is by far the most powerful proposed observatory for finding large numbers of planetary systems. It answers the following questions: How many planets are there? How are they distributed in mass and distance from their parent stars, and in distance from the Galactic Center? How many have large moons? How many have been expelled from their systems? None of these questions are fully addressed by other techniques particularly if the abundance is low. MPF will do this by observing microlensing signals from 100 million stars in the Galactic bulge for 4 observing seasons, and it will have sensitivity to planets with masses as low as 0.1 M\oplus at separations > 0.7 AU. MPF will be sensitive to analogs of all the planets in the solar system except for Mercury and Pluto and will complement the Kepler mission.
Microlensing Planet Search Project ( MPS )

Microvariability and Oscillations of STars ( MOST )
MOST is Canada's first space science microsatellite and its first optical space telescope project, aiming for launch in late 2001. MOST is designed to measure (as its acronym implies) Microvariability & Oscillations of STars in broadband light with a precision of a few micromagnitudes over timescales from minutes to days. The resulting eigenfrequency data will be used primarily for stellar seismology, to probe the structure and ages of Sun-like stars, magnetic stars, Wolf-Rayet stars and halo subdwarfs. The subdwarfs are expected to yield age estimates which would place a meaningful lower limit on the age of the Universe. MOST should also be capable of confirming the presence of giant extrasolar planets identified in Doppler surveys.

Midcourse Space Experiment ( MSX )
The MSX observatory is a Ballistic Missile Defense Organization project which offers major benefits for both the defense and civilian sectors. It was launched on a Delta II vehicle on April 24, 1996, into a 900 km, polar, near-Sun synchronous orbit. The spacecraft featured an advanced multispectral image capability to gather data on test targets and space background phenomena.
The infrared sensors operated at 11 to 12 degrees Kelvin by employing a solid hydrogen cryostat. The IR instruments span the range 4.2 - 26 microns. The focal plane array consists of five bands and the radiometer beam-size is more than 25 times smaller than IRAS. As a result, much greater spatial resolution than anything currently available has been obtained. The cryogen phase of the mission ended on 26 February 1997. During the ten month cryogen phase of the mission over 200 Giga Bytes of data on Celestial Backgrounds were obtained.
See the MSX Celestial Backgrounds Team Home Page for additional details.

Molonglo Observatory Synthesis Telescope ( MOST )
The MOST consists of two cylindrical paraboloids, 778m x 12m, separated by 15m and aligned East-West. A line feed system of 7744 circular dipoles collects the signal and feeds 176 preamplifiers and 88 IF amplifiers. The telescope is steered by mechanical rotation of the cylindrical paraboloids about their long axis, and by phasing the feed elements along the arms. The resulting `alt-alt' system can follow a field for +/- 6 hours (necessary for a complete synthesis with an East-West array) only if the field is south of declination -30 degrees. For fields near this limit the signal-to-noise ratio is considerably lower for the first and last hour or so due to the lower gain of the system at large `meridian distance' angles.

Project Galileo: Bringing Jupiter to Earth
Launched in 1989, the Galileo spacecraft arrived at Jupiter on December 7, 1995, when it fired its main engine for a successful orbit capture around Jupiter. On that day, Galileo's atmospheric probe plunged into Jupiter's atmosphere and relayed information on the structure and composition of the solar system's largest planet. The spacecraft's orbiter will spend the next two years orbiting the giant planet, studying Jupiter and its moons (encountering one moon during each orbit), and returning a steady stream of images and scientific data. The first two encounters were successfully performed with Jupiter's largest moon, Ganymede, on June 27, 1996 and September 6, 1996.

Schw�bischen Sternwarte
The Swabian Observatory was founded in 1919. It is a non-profit-making organisation. Since January 8th 1922 we operate an observatory located on a hill in Stuttgart. The focal point of our astronomical work is the observation of occultations of stars by the moon, the planets and their satellites, asteroids and also mutual events. We measure the occultation timings with video and photoelectric equipment up to 10.5 mag with an accuracy of +/-0.01s and up to 13.5 mag with an accuracy of +/-0.1s. We send our results to IOTA, EAON, BAA and ILOC. Sometimes we make an excursion to observe grazing events with our transportable telescopes, for example a Meade 2080HTC. Another main emphasis is the observation of variable stars, mainly Mira type stars. Normally we measure stars up to 15mag. At the moment we are beginning to observe variable stars with the CCD camera ST-6. We send our results to AAVSO, AFOEV and BAV. [in German]

Sydney University Molonglo Sky Survey ( SUMSS )
SUMSS is a deep radio survey of the entire sky south of declination -30 degrees, made using the Molonglo Observatory Synthesis Telescope, operating at 843MHz and recording right-circular polarization.
SUMSS matches (approximately) the resolution and depth of the NRAO-VLA Sky Survey (NVSS). The principal data products are mosaics which cover a 4x4 degree square on the sky. The centres of the mosaics mirror the NVSS centres in the north. The resolution is 45" x 45"/sin(dec), and the rms noise limit varies from 1.3 to 2mJy/beam (lower toward the south celestial pole).
The survey began in March 1997 and will take eight years to complete. SUMSS is suported by funding from the Australian Research Council.
The primary reference for a description of the survey is: Bock, D., Large, M. and Sadler, E.
