Kepler Published Planets is a catalog of confirmed exoplanets discovered by NASA's Kepler mission. The metadata is compiled from the NASA Exoplanet Science Institute (NExScI) catalogs and originates from published papers. The dataset was last updated on March 13, 2026.
NASA's NED Cone Search service queries a master list of extragalactic objects based on proximity to a specified celestial coordinate. The service is maintained by the National Aeronautics and Space Administration and was last updated in March 2026. It likely contains positional and identification data for astronomical objects beyond our galaxy.
A PhD thesis by Harvey MJ (2009) developed techniques for classifying marine benthic habitats using hyperspectral imagery in oligotrophic, temperate waters. The source data is hosted in the National Spectral Database (NSD) Aquatic Library. The imagery was collected in Western Australia, specifically around Rottnest, Marmion, and Shoalwater, during 2006-2007.
From 21 Jan 2014 to 19 Nov 2014, the Rosetta spacecraft's RPCIES instrument collected calibrated data during the Prelanding phase targeting comet 67P/Churyumov-Gerasimenko. The dataset is published by the National Aeronautics and Space Administration (NASA) as part of the International Rosetta Mission. It contains measurements from the comet's approach and early orbital phase.
NASA's Ulysses COSPIN-LET dataset provides 20-day average fluxes of energetic particles. It contains pulse-height-analysis-based fluxes for Oxygen, Nitrogen, and Neon across multiple energy ranges per nucleon, along with Poisson uncertainties. The data was last updated on March 13, 2026.
Daily average fluxes for protons in five energy ranges (2-4, 4-6, 6-8, 8-16, 16-20 MeV) and alpha particles in three ranges (4-6, 6-9, 11-20 MeV/n), including Poisson uncertainties. The data originates from the Ulysses spacecraft's COSPIN Low Energy Telescope instrument and is provided by NASA. The dataset was last updated on March 13, 2026.
Six-hour averages of selected cosmic ray fluxes measured by the Voyager 1 spacecraft's Cosmic Ray Subsystem (CRS) instrument during its cruise mode. The data originates from NASA and is stored in BIN format. The dataset was last updated on March 13, 2026.
NASA's Ocean Biology DAAC produces this near real-time (NRT) Level-3 product quantifying the spectral center of ocean color. The Apparent Visible Wavelength (AVW) variable, reported in nanometers, summarizes the shape of water-leaving reflectance to indicate water type. This NRT version uses the best-available ancillary data but its inputs and calibration are described as less than optimal.
NASA's Ocean Biology DAAC provides near real-time satellite data quantifying the apparent visible wavelength of ocean water. The single geophysical variable, avw in nanometers, summarizes the spectral shape of water-leaving reflectance to indicate water type. This version 3.1 product offers a snapshot from a single orbit using the best-available ancillary data at the time of processing.
A catalog of 92 X-ray point sources detected in the central region of the barred spiral galaxy NGC 2903. The data originates from a deep observation by NASA's Chandra X-ray Observatory using the ACIS-S instrument on March 7, 2010. The study analyzes diffuse emission and point sources to investigate the nuclear starburst, potential galactic winds, and the absence of an active galactic nucleus.
NASA's Galaxy Evolution Explorer (GALEX) observation log contains extant and planned observations from the satellite observatory launched on April 28, 2003. The table is provided by the HEASARC to assist the high-energy astrophysics community and is updated within a week of its source file. GALEX performed the first space ultraviolet sky survey across imaging and spectroscopic modes.
Fermi LAT's Second Catalog of Gamma-Ray Pulsars (2PC) summarizes 0.1 GeV gamma-ray pulsar detections from the Fermi satellite's Large Area Telescope. The catalog divides pulsars into three groups: millisecond, young radio-loud, and young radio-quiet pulsars, and provides analysis of pulse profiles, energy spectra, and off-peak phase intervals. This database was constructed by NASA's HEASARC from tabulated data published in 2013.
NASA HEASARC provides a catalog of 2,845 radio sources detected above a 6-sigma threshold from Giant Metrewave Radio Telescope observations. The data covers an area of approximately 5 square degrees in the Lockman Hole region at 610 MHz, with observations taken on July 24-25, 2004. This table was created in February 2012 based on an external catalog from the CDS.
NASA HEASARC provides a catalog of 2500 radio sources detected above a 6-sigma threshold from Giant Metrewave Radio Telescope observations. The data covers approximately 9 square degrees of the ELAIS-N1 field at 610 MHz, with pointings achieving an rms sensitivity between ~40 and ~70 microJansky. This table was created in February 2012 based on a published CDS catalog.
258,997 stellar records form the Smithsonian Astrophysical Observatory Star Catalog, incorporating cross-identifications and corrections up to 1991. The HEASARC provides this version, which includes J2000.0 positions and proper motions computed by the U.S. Naval Observatory.
Hitomi, a JAXA satellite launched on February 17, 2016, collected about one month of high-energy X-ray data before contact was lost on March 27, 2016. The catalog contains 42 observation sequences from six celestial objects, including the Perseus cluster and the Crab Nebula, using four instruments covering 0.3-600 keV. NASA HEASARC ingested this database table in June 2017 to provide access to the mission's data archive.
NASA HEASARC provides a catalog of 33 discrete X-ray sources detected in a 60-ks Chandra ACIS-S observation of the galaxy NGC 3556 (M108). The observation was taken on 2001 September 8-9, and the table was created in August 2015 based on CDS Catalog J/ApJ/598/969. It includes candidate identifications for the galactic nucleus, an ultraluminous X-ray source, an X-ray binary, and giant H II regions.
A catalog of 374 and 354 radio sources detected at 4.5 and 7.5 GHz from the Very Large Array Gould's Belt Survey. The data covers 2.26 square degrees of the Orion Molecular Clouds, with 148 sources associated with known young stellar objects and 86 new candidate young stars. Observations were conducted by the National Radio Astronomy Observatory in three epochs during 2011.
145 X-ray selected galaxy groups and clusters with spectroscopic redshift measurements, extending a previous survey by 67 new optically confirmed systems. The data results from cross-matching serendipitous X-ray sources from the 2XMMi-DR3 catalog with optical data from the Sloan Digital Sky Survey (SDSS-DR10). NASA HEASARC created this table in July 2014 based on a published catalog.
A catalog of 10,040 sources identified in the deepest i-band image from the Hubble Ultra Deep Field (UDF) program. The dataset includes an additional 100 manually added sources and 39 sources detected in the z-band, compiled by NASA HEASARC in May 2005. Observations were conducted by the Hubble Space Telescope from September 2003 to January 2004.
