Astrophysics Data System (ADS)
On behalf
of NASA, the Smithsonian Astrophysical Observatory operates the Astrophysics
Data System (ADS), which contains an archive of the astronomy literature
available from a searchable interface. The ADS contains over 3 million
abstracts from journal articles, conference proceedings, reports, theses,
and more, divided into databases by content (Astronomy, Space Instrumentation,
Physics, Geophysics, and Preprints). Also included in the ADS are
3 million scanned pages, covering the major astronomy journals back to
volume 1, many smaller journals, as well as a significant chunk of the
old observatory publication literature. The ADS can be accessed
through the World Wide Web URL: adswww.harvard.edu.
Einstein Observatory
The Einstein Observatory Data Archive
consists of x-ray images obtained by the Einstein Observatory Satellite
(HEAO-B). This satellite carried the first large x-ray telescope capable
of focusing images of astronomical objects. The spacecraft operated from
November 1978 to April 1981. Images and spectra of over 4,000 astronomical
objects were obtained and are stored electronically at the Smithsonian
Astrophysical Observatory (SAO). The data have been on-line for many years.
At this time they are temporarily unavailable until we have migrated
this archive to more modern hardware.
Chandra X-ray Observatory
NASA's Chandra X-ray Observatory was launched on July 23, 1999, and carries
two instruments, ACIS and HRC, providing the world with the highest spatial
resolution X-ray telescope to date: about half an arcsecond. It
has generated X-ray images of numerous celestial objects with unprecedented
detail. Through the use of transmission gratings Chandra is also capable
of providing very high resolution spectral data. This is an on-going
mission. The SAO operates the mission under contract with NASA in its
Chandra X-ray Center (CXC) which can be found on the web at: http://cxc.harvard.edu/
The Chandra Data Archive (CDA) contains almost all information and data
that were generated by and in connection with this mission, including
observation catalog, telemetry, processed data, final data products, and
calibration data. Observations are linked to publications in the
professional literature through the ADS. In general, observations
proposed by members of the astronomical community remain proprietary for
a year. After that period the data are released to the public domain.
