The NASA Star and Exoplanet Database (NStED) is an on-line astronomical stellar and exoplanet catalog and data service that collates and cross-correlates astronomical data and information on exoplanets and their host stars.
An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.
Although the primary focus of astroinformatics is on the large worldwide distributed collection of digital astronomical databases, image archives, and research tools, the field recognizes the importance of legacy data sets as well—using modern technologies to preserve and analyze historical astronomical observations.
An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. The oldest and largest are star catalogues .
ADQL is a specialized variant of the SQL query language adapted for accessing the astronomical datasets of the virtual observatory, [2] via the Table access protocol (TAP). [3] ADQL is designed to handle large datasets distributed over several locations, [4] while not retrieving data that is not needed. [5]
ESASky [1] is a web-based tool developed by the European Space Agency (ESA) to provide access to astronomical data. It aims to offer a user-friendly interface for exploring various datasets, including images, catalogues, and spectra, collected from ESA missions like Planck, Herschel, Gaia, HST, XMM-Newton, and INTEGRAL, among others.
The NASA/IPAC Extragalactic Database (NED) is an online astronomical database for astronomers that collates and cross-correlates astronomical information on extragalactic objects (galaxies, quasars, radio, x-ray and infrared sources, etc.). NED was created in the late 1980s by two Pasadena astronomers, George Helou and Barry F. Madore.
Screenshot of Aladin User Interface (Version 10) Aladin is an interactive software sky atlas, created in France.It allows the user to visualize digitized astronomical images, superimpose entries from astronomical catalogues or databases, and interactively access related data and information from the SIMBAD database, the VizieR service and other archives for all known sources in the field.
