ISEE-1 and ISEE-2 were launched on October 22, 1977 into elliptical orbits to study the Earth's magnetosphere and solar wind. The University of Iowa Plasma Wave Instrument (PWI) on ISEE-1 provided high-time-resolution spectrum measurements via a 20-channel Electric Spectrum Analyzer connected to electric dipole antennas. This dataset contains rapid sample measurements from that instrument, intended to resolve wave emissions that are bursty or nonlinear.
John Greer's dataset provides forensic receipts for the Topological Information (TIE) Framework, proposing a mechanical metric model to explain anomalies like Dark Matter and Dark Energy.

The dataset contains files like a unified metric ledger CSV, LHC stress test data, and a force audit visualization.
Almost 140 hours of Very Large Array observations between December 2001 and January 2004 produced this deep radio source catalog at 1400 MHz. The catalog, created by NASA HEASARC in 2010, lists sources detected above a 5-sigma threshold from a region centered on the Spitzer SWIRE survey. It is described as the deepest survey in terms of radio source density, with an estimated six sources per square arcminute at 15 microJansky.
The Galactic Center P-Band (330 MHz) Survey (GCPS) provides wide-field, subarcminute-resolution Very Large Array (VLA) imagery of the Galactic center region. Observations were conducted in two sets: one in October 1996 and another between March 1998 and May 1999. This Browse table was created by NASA's HEASARC in May 2005 based on catalog data from the CDS.
The CRABTIME database contains the Crab Pulsar Monthly Ephemeris covering the period from February 15, 1982 (MJD=45015) to near the present. It was created by Dr. Andrew Lyne and collaborators at Jodrell Bank Observatory and is maintained and updated by NASA's HEASARC. The database includes calculated parameters like pulsar period and its first derivative.
The North Galactic Cap region, specifically Kepler K2 mission Field 1, is covered by this radio continuum survey. It contains source catalogs with 1,085, 1,468, and 7,445 detections from Murchison Widefield Array and Giant Metrewave Radio Telescope observations between 140-200 MHz, conducted contemporaneously with K2 in 2014 and historically from 2010-2012. The dataset was aggregated by NASA from the referenced astronomical survey.
27-day Bartels Rotation periods structure the time-averaged energetic charged particle fluxes. The dataset contains flux data for 24 elements across seven energy ranges per element, collected by the Cosmic Ray Isotope Spectrometer on NASA's Advanced Composition Explorer spacecraft. The instrument was designed with greater collection power than previous satellite instruments.
The VLA Lockman Hole 1400-MHz Radio Source Catalog contains 1,479 entries for faint radio sources, including 1,450 sources and 29 individual components for multi-component sources. This catalog was created by NASA HEASARC in February 2012 based on data from the Very Large Array (VLA) and the Giant Metrewave Radio Telescope (GMRT), with observations conducted in 2006. It represents deep imaging data with a noise level of approximately 6 microJy/beam at 1.4 GHz.
The Giant Metrewave Radio Telescope Lockman Hole 610-MHz Radio Source Catalog 3 contains 1,619 entries, including 1,585 sources and 34 individual components for multi-component sources. It was created by NASA's HEASARC in February 2012 based on data from the Giant Metrewave Radio Telescope in India and the Very Large Array. The data were collected during six 12-hour sessions in February and July 2006, providing the deepest 610-MHz imaging reported at the time of publication.
48,850 compact radio sources identified at 843 MHz by the Molonglo Observatory Synthesis Telescope. This second-epoch catalog covers the southern Galactic plane within specific longitude and latitude ranges, with positions accurate to 1-2 arcseconds. The HEASARC table was created in January 2008 based on a CDS catalog from 2007.
The Belgian/UK Ultraviolet Sky Survey Telescope (S2/68) on the ESRO TD1 satellite performed a controlled scan of the entire sky. It measured absolute ultraviolet flux distributions for 31,215 stars down to 10th visual magnitude across four specific passbands. The catalog results from this sky-scan experiment, with data originally provided by the Royal Observatory in Edinburgh and later recreated by NASA HEASARC.
209 sources identified at 31 GHz from a 7.7 deg² sky survey conducted between late-2005 and mid-2007, with flux levels from 0.7 mJy to ~200 mJy. The catalog was created by NASA HEASARC in June 2012 based on data from the Owens Valley Radio Observatory's SZA interferometer. It includes derived source counts and comparisons with 1.4 GHz and 5 GHz archival data.
Low-Frequency Array (LOFAR) observations of the Herschel-ATLAS North Galactic Pole survey area, covering around 142 square degrees of sky in the 126-173 MHz frequency range. The catalog, produced by NASA, presents a 5-sigma source list derived from four pointings with imaging at a resolution of ~10 x 6 arcsec and off-source noise ranging from 100 μJy/beam to 2 mJy/beam. The reference paper includes initial science results on the radio/far-infrared correlation, number counts, luminosity functions, and radio galaxy life cycles.
The Las Campanas Redshift Survey (LCRS) catalog contains 94,959 objects with photometric data, of which 27,021 have spectroscopic redshift information. It was created by NASA HEASARC in 2010 based on data from a CCD-based R-band survey covering over 700 square degrees in six strips across the northern and southern Galactic caps. The survey's median redshift is about 30,000 km s⁻¹ and it was designed to study large-scale galaxy clustering and structure.
Westerbork in the Southern Hemisphere (WISH) is a 352 MHz radio survey covering 1.60 steradians of the southern sky, excluding the Galactic Plane. The catalog contains 90,357 flux density measurements from a collaboration between the Netherlands Foundation for Research in Astronomy and Leiden Observatory. This table was created by NASA HEASARC in November 2010 based on CDS catalog VIII/69A.
UCAC5 provides mean positions and proper motions for over 107 million stars, derived from a new astrometric reduction of US Naval Observatory all-sky observations. The catalog combines UCAC5 data with Gaia DR1 to achieve typical proper motion accuracies of 1 to 2 mas/yr for stars between 11th and 15th magnitude. This dataset is hosted by NASA and was last updated in March 2026.
31 separate 12-hour observations from the Molonglo Observatory Synthesis Telescope were combined into a single image with 62 arcsec x 43 arcsec resolution. The catalog presents 843-MHz radio sources, their ATLAS counterparts, and spectral index distributions in the ELAIS-S1 field, created by the NASA HEASARC in January 2013. It investigates spectral index trends with flux density and redshift, and includes an initial sample of faint compact steep-spectrum sources.

The data is version 2.0, produced by a fixed EGSE software correcting an issue where the old version produced incomplete products reduced by one line.
