The survey covers 150 square arcminutes in the GOODS-North field to an average 3 sigma depth of 40 microJanskys. NASA produced this catalog, which was last updated on March 13, 2026.
The GOODS-S IRS 16 micron Catalog contains infrared source observations from the Great Observatories Origins Deep Survey. It covers 150 square arcminutes in each of the two GOODS fields (North and South) to an average 3 sigma depth of 40 and 65 microJy, respectively. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a spectropolarimetry instrument flown on Space Shuttle missions in December 1990 and March 1995. It provides a unique dataset of medium-resolution ultraviolet spectropolarimetry for various astronomical targets. The data was collected by NASA as part of the ASTRO instrument suite.
Roughly 28,000 astronomical observations, including novae and supernovae, were cross-correlated from the MAST Table of Representative Spectra with targets from the Skiff Spectral and Sky2000 catalogs and Simbad. More than 22,000 of these observations have assigned spectral types. The data was compiled by the National Aeronautics and Space Administration and last updated in March 2026.
Synoptic maps summarize short-term and long-term coronal evolution. The resource contains East and West limb maps from Cor1 and Cor2 coronagraphs, HI1/2-A/B imager maps, and central meridian maps from the EUVI telescope. Maps are available for each Carrington Rotation since the beginning of the STEREO mission.
Spin-integrated counting rates for protons, helium, and electrons across multiple energy channels, averaged over 10-minute intervals. The dataset includes eight-sectored count rates for specific proton and electron energies and single detector sensor rates. Data originates from the Ulysses spacecraft's COSPIN Kiel Electron Telescope instrument, provided by NASA.
An ASCII file contains isotopic fractions and their uncertainties for 56 specific isotopes relative to isotope-integrated elemental abundances. The data covers 15 chemical elements and is based on 1978-1981 observations of ~50-500 MeV/n cosmic rays by the U. Chicago experiment on the ISEE 3 spacecraft. Each ratio is linked to its source publication.
10-minute average fluxes of protons, alpha particles, and heavier nuclei (Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Zā„10) across multiple energy ranges, along with eight-sectored proton fluxes and electron count rates. The data was collected by the Ulysses spacecraft's COSPIN-LET instrument and is provided by the National Aeronautics and Space Administration. The dataset was last updated on 2026-03-13.
Synoptic maps from the STEREO mission's SECCHI EUVI telescope illustrate the evolution of the solar corona. The resource contains East and West limb maps from coronagraphs and imagers, plus central meridian maps for each Carrington Rotation since the mission's start. Maps show the corona's transition from a simple two-sectored structure to a complex multi-sectored one, with distortions linked to active regions, the current sheet, and coronal mass ejections.
NASA HEASARC provides a catalog of over 130,000 quasar candidates with matched optical and near-infrared photometry. The data results from matching the Sloan Digital Sky Survey (SDSS) DR6 Photometric Quasar catalog to the UKIRT Infrared Digital Sky Survey (UKIDSS) Large Area Survey Data Release 3, covering approximately 1200 square degrees. This table was created by the HEASARC in September 2012 based on an external catalog file.
A catalog of 325 Chandra-detected compact X-ray sources in the nearby star-forming galaxy M 83, classified by donor mass using multi-band Hubble Space Telescope imaging. The dataset, created by NASA's HEASARC in March 2023, builds upon deep Chandra ACIS imaging and HST observations taken between 2009 and 2012. It presents X-ray luminosity functions for low-mass, high-mass, and intermediate-mass X-ray binaries.
Daily and synoptic solar maps capture the Sun's magnetic field and helium line strength from 1985 onward. Data originates from the National Solar Observatory's Vacuum Telescope on Kitt Peak, Arizona. Observations are structured by Carrington rotation, with synoptic maps representing one full solar rotation each.
A catalog of 3165 known extragalactic radio sources observed at 31 GHz over 143 square degrees of the sky. The data were collected using the 100m Green Bank Telescope in 2006 and the 40m Owens Valley Radio Observatory telescope from 2000 to 2002, primarily targeting active galactic nuclei. This table, created by NASA HEASARC in June 2012, contains results from the GBT campaign covering 1490 sources and characterizes the spectral index distribution to predict source counts.
721 X-ray sources detected in the NGC 7000/IC 5070 star-forming region, combining data from Chandra and XMM-Newton observatories. The catalog, created by the HEASARC in July 2017 based on CDS data, includes optical and near-IR identifications from IPHAS, UKIDSS, and 2MASS to characterize young stellar populations. The study aims to identify candidate young stars, analyze spatial distributions, and map reddening across the region.
From September 2000 to December 2002, the Owens Valley Radio Observatory 40-m telescope conducted a 31-GHz survey of 3165 known extragalactic radio sources over 143 square degrees of sky. The catalog contains data on 1675 sources, with an 11% detection rate, and was created by NASA HEASARC in June 2012 based on published research. This work characterizes the impact of discrete source foregrounds on arcminute-scale anisotropy measurements.
A retrospective study compares PROMPT-based and structured home-based language training for 124 children with autism spectrum disorder and speech delay. The analysis uses propensity score matching to evaluate outcomes in language developmental stages and image expression ability before and after a 3-month intervention.
A catalog of 64,646 candidate galaxy clusters with masses greater than ~10^13 solar masses, derived from the Sloan Digital Sky Survey Data Release 7. The authors used an optical to X-ray code to estimate X-ray luminosities from ROSAT All-Sky Survey images, with 34,522 clusters having a signal-to-noise ratio greater than 0. The dataset was last updated on 2026-03 13 and is hosted by the National Aeronautics and Space Administration.
The Hewitt & Burbidge (1993) Revised and Updated Catalog of Quasi-Stellar Objects contains 7,315 objects, including 89 BL Lac objects, known as of December 31, 1992. NASA HEASARC created this database in February 2001 based on the CDS/ADC Catalog VII/158. It provides information on names, positions, magnitudes, colors, and emission-line redshifts for these astronomical objects.
Four channels of fast time resolution (50 ms) Bremsstrahlung X-ray spectra detected with a NaI Scintillator, covering an energy range from 0 MeV to 1.5 MeV. The BARREL Mission was a NASA Living with a Star Mission of Opportunity, launching over 50 stratospheric balloons from Antarctica (2013-2014) and Sweden (2015-2016) to study electron losses from Earth's Radiation Belts. Data was collected at stratospheric altitudes near the antarctic and arctic circles to provide measurements of relativistic electron precipitation.
Four channels of fast time resolution (50 ms) Bremsstrahlung X-ray spectra detected with a NaI Scintillator, covering an energy range from 0 MeV to 1.5 MeV. The data was collected by NASA's BARREL mission, a multiple-balloon investigation designed to study electron losses from Earth's Radiation Belts, with campaigns conducted from Antarctica in 2013-2014 and from Sweden in 2015-2016. Over 50 stratospheric balloons were launched across the four campaigns, providing measurements to characterize the spatial and temporal variations of relativistic electron precipitation.
