Approximately 590 square degrees of sky, concentrated on the Large and Small Magellanic Clouds, were scanned with long-exposure infrared observations during the final months of the 2MASS observatory. The National Aeronautics and Space Administration created this metadata table for scans that probe about one magnitude deeper than the main survey. Data was last updated in March 2026.
398 young stellar objects (YSOs) in the Orion Nebula Cluster are cataloged with JHK and IRAC infrared photometry and protostar classifications. The data was assembled from observations by the HST Treasury Program, WFI at ESO 2.2m, ISPI at CTIO 4m, and Spitzer IRAC. This online catalog was created by NASA HEASARC in October 2010 based on tables from the reference paper.
The Spitzer Science Center and Infrared Science Archive released enhanced imaging products from the Spitzer Heritage Archive. These products include mosaic images and a source list of photometry for compact sources from the IRAC and MIPS instrument channels. The source list prioritizes reliability over completeness, meaning it is not complete at any flux density.
The 2dF QSO Redshift Survey (2QZ) catalog covers 721.6 square degrees of sky in two declination strips across the South and North Galactic Gaps. It contains 44,576 color-selected objects, including 23,338 quasars, 12,292 galactic stars, and 4,558 compact narrow emission-line galaxies, based on Anglo-Australian Telescope 2dF spectroscopic observations from 1997 to 2002. This catalog, created by NASA HEASARC in 2010, is described as the largest homogeneous QSO catalog at its faint magnitude limits.
GLIMPSE 3D is a large-area infrared survey of the Galactic plane conducted by the Spitzer Space Telescope. The Epoch 1 Catalog is a subset of the project's Archive, containing point sources with a signal-to-noise ratio greater than 5 in at least one band and photometric uncertainty typically under 0.3 magnitudes. The data was produced by the National Aeronautics and Space Administration and was last updated in March 2026.
The GLIMPSE II Epoch1 Catalog is a subset of point source data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire, produced by the National Aeronautics and Space Administration. It contains infrared observations of the central region of the Galaxy, with latitude coverage varying from ±1° to ±2° and excluding the Galactic center. The catalog is derived from two-epoch observations taken in September 2005 and April 2006, with sources requiring a signal-to-noise > 5 in at least one band.
A catalog of 1,055 quasars from the Large Bright Quasar Survey provides celestial positions, redshifts, and magnitudes. The data was compiled by NASA HEASARC in July 1999, incorporating corrections and updates from the original discovery papers. Positions were rederived using the PPM catalog for an improved reference frame.
A 1999 catalog from NASA HEASARC summarizes 397 bright, soft X-ray sources from the ROSAT All-Sky Survey at high galactic latitudes. It provides spectroscopic identifications for 108 sources, with the largest classes being AGN, magnetic cataclysmic variables, and hot white dwarfs. The database was created based on tables provided by the authors to CDS/ADC.
219 Fanaroff and Riley class I edge-darkened radio galaxies (FR Is) form the main FRICAT catalog, with an additional 14 smaller sources in the sFRICAT sample. The catalog was built by the authors by combining observations from the NVSS, FIRST, and SDSS surveys and is hosted by NASA HEASARC. This HEASARC table was created in February 2017 based on data from the Astronomy & Astrophysics website.
2,991 extragalactic supernovae discovered from 1885 until December 12, 2004, along with data on their host galaxies. The Sternberg Astronomical Institute compiled this catalog, with host galaxy data integrated from multiple astronomical catalogs like RC3, UGC, and PGC. NASA HEASARC created this table version in June 2005 based on a CDS source.
482 X-ray point sources were detected in the lenticular galaxy NGC 3115 using 1.1 megaseconds of Chandra observatory data. The catalog, produced by NASA, includes 136 candidate low-mass X-ray binaries in the field and 49 in globular clusters, with luminosities ranging from 10^36 to 10^39 erg s^-1. Observations were conducted in three epochs: 2001, 2010, and 2012.
Two-epoch observations from September 2005 and April 2006 imaged the central region of the Galaxy. The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSEII) Archive consists of point sources with a signal-to-noise > 5 in at least one band, provided by the National Aeronautics and Space Administration. Photometric uncertainty is typically less than 0.3 magnitudes.
NASA HEASARC provides a catalog of 7,855 radio-loud candidate gamma-ray emitting blazars, assembled from WISE mid-infrared sources cross-matched with radio surveys. The catalog classifies sources as BL Lacs, FSRQs, or mixed candidates, with 1,295 sources re-associated as confirmed blazars. This table was created in December 2014 based on a reference paper from the ApJS website.
Monitor Proportional Counter (MPC) data from the Einstein Observatory (HEAO-2) operational from 1978 to 1981. The instrument monitored 1 to 20 keV X-ray flux with a 1.5-degree field of view and an active area of 667 square cm. This catalog is provided by NASA HEASARC, with one duplicate entry removed in June 2019.
1898 H-alpha emission-line stars and small nebulae in the Small Magellanic Cloud were discovered in an objective-prism survey using the 0.90m Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory. The catalog, created by NASA HEASARC in November 1997, includes newly identified planetary nebulae, compact H II regions, and late-type stars. It provides continuum intensities, H-alpha emission line shapes and strengths, coordinates, and cross-identifications for the listed objects.
A database table of pointed telescope observations from NASA's Compton Gamma-Ray Observatory (CGRO), launched in 1991 and de-orbited in 2000. The table contains observations for Cycles 1 through 9, with viewing periods typically two weeks long, and was last updated in November 2001. The information was provided by the Compton Observatory Science Support Center, with galactic coordinates added by the HEASARC in 2005.
Pathogen detection results from 400 pharyngeal swabs collected from influenza-like illness (ILI) patients in Guilin, China, between October 2023 and October 2024. The data, published by Jin Cao on figshare, includes detection rates for 18 pathogens, co-infection analysis, and epidemiological characteristics by age and season. The overall pathogen-positive rate was 74.0%, with Influenza, SARS-CoV-2, and Mycoplasma pneumoniae being the most common.
The Tartarus database provides systematically analyzed data from ASCA X-ray telescope observations of active galactic nuclei. It contains results for 611 designated AGN observing sequences, including source and background event files, spectra, response files, images, and light curves. This version 3.1 was created by the Tartarus Team and ingested by NASA HEASARC in August 2005.
GLIMPSE3D is a catalog of infrared point sources from the Spitzer Space Telescope's IRAC instrument, mapping vertical extensions of the Galactic plane. The dataset is a subset of a larger archive, with sources meeting a signal-to-noise threshold and photometric uncertainty typically below 0.3 magnitudes. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
118,209 stars were selected from over 214,000 candidates to form the observing program for the European Space Agency's Hipparcos astrometry mission. The catalog includes positions, proper motions, magnitudes, colors, and, where available, spectral types, radial velocities, and variability information. This service is provided by NASA HEASARC.
