The Spitzer Extragalactic First Look Survey catalog contains mid-infrared imaging data from the Spitzer Space Telescope. The 67-hour survey, conducted in late 2003, covers 4 square degrees centered at J1718+5930 and aims to characterize extragalactic sources down to sub-millijansky levels. The dataset is provided by the National Aeronautics and Space Administration and includes ancillary ground-based optical and radio data.
The Molonglo Reference Catalog lists 12,141 discrete radio sources with flux densities greater than 0.7 Jy. It covers the declination range +18.5 degrees to -85 degrees in 1950 coordinates, excluding regions within 3 degrees of the Galactic equator. NASA's High Energy Astrophysics Science Archive Research Center (HEASARC) provides this service.
A catalog of observations made by the Broad Band X-Ray Telescope (BBXRT), including spectral and lightcurve products for each of the 10 pixels per observation. The data is provided by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC). The dataset was last updated on 2026-03-13.
The 2MASS Large Galaxy Atlas provides photometric data for galaxies ranging in size from 2 to 30 arcminutes. It was produced by the National Aeronautics and Space Administration and offers a typical resolution of approximately 3 arcseconds in the J, H, and Ks infrared bands. The atlas provides aggregate galaxy flux and detailed infrared morphology views.
A 67-hour survey conducted in late 2003, this dataset is a mid-infrared point source catalog from the Spitzer Space Telescope's Extragalactic First Look Survey. It covers 4 square degrees of imaging centered at J1718+5930, aiming to characterize extragalactic source populations down to sub-millijansky levels. The data was produced by the National Aeronautics and Space Administration (NASA) and includes ancillary observations from ground-based optical and radio telescopes.
National Aeronautics and Space Administration provides a collection of all published ground-based asteroid radar detections. The data set includes disc-integrated radar properties extracted from published papers and is maintained by Lance A.M. Benner, based on the original collection by Steven J. Ostro. The file was last updated on March 13, 2026.
FlowVortex published a dataset titled 'Large Spectrum Prediction Dataset' on the Hugging Face platform in June 2026. The dataset's specific content, size, and structure are not detailed in the available metadata. Its title suggests it contains data related to predicting or modeling spectra, which could be used in fields like astronomy or signal processing.
Late Miocene-Early Pliocene microfossil data distinguishes the Bookpurnong Beds from older sediments in the central west Murray Basin. The dataset identifies key dinoflagellate species like Melitasphaeridium aequabile and Tuberculodinium vancampoae for stratigraphic correlation. It was contributed by the Australian Ocean Data Network and last updated in April 2026.

Hourly count rates from the University of Iowa Geiger Tube Telescope (GTT) carried on the Pioneer 11 spacecraft. The data includes five distinct rates for electrons and protons across different energy thresholds, such as electrons > 0.06 MeV plus protons > 25 MeV. The National Aeronautics and Space Administration (NASA) provides the data as annual ASCII files, with hourly averages computed at the NSSDC from 15-minute data.
Hourly averages of energetic particle counts from the Pioneer 10 spacecraft's Geiger Tube Telescope. The data includes five distinct rate combinations for electrons and protons at different energy thresholds, computed by NSSDC from offline 15-minute data. Files are accessible in annual ASCII format via FTP.
Supplementary data supporting an investigation into reproducibility challenges in circular dichroism spectroscopy of FmocFF peptide gels. The dataset is published on figshare under a CC-BY-4.0 license by author Dave Adams and was last updated on 2026-05-05. Its 807.6 KB size suggests a limited scope.
Three field surveys in Darwin Harbour, Australia, studied the effect of sewage-derived nutrient loads on biogeochemical processes. The dataset compares water quality, sediment composition, and metabolic rates across three creeks with varying pollution levels: hypertrophic Buffalo Creek, oligotrophic-mesotrophic Myrmidon Creek, and a pristine Reference Creek. The study was published by Geoscience Australia Data.
Bo Sun's dataset contains correction results for seismic design response spectra calculated by the GCPSO-GIT model across different site categories. The dataset is stored in an XLS file with a size of 5.5 KB and was last updated on April 20, 2026. It is shared under a CC-BY-4.0 license on the figshare platform.
Version 2.0 calibrated images of comet 9P/Tempel 1 were acquired by the Deep Impact High Resolution Instrument Visible CCD. The data set includes uncleaned radiance, cleaned radiance, and I-over-F data with improved geometry. NASA collected the data from 1 May through 4 July 2005.
2006-2007 hyperspectral imagery data for classifying marine benthic habitats in oligotrophic, temperate waters, hosted in the National Spectral Database. The data is associated with a PhD thesis from Murdoch University and is managed by the Australian Ocean Data Network.
Approximately 36,000 images from the SOHO spacecraft's LASCO C2 telescope, prepared for a Topcoder challenge. The data comprises observations of extremely faint, noise-level comets that are difficult for automated algorithms to detect. NASA provides this data with no restrictions on use.
The Large Magellanic Cloud was surveyed by the Spitzer Space Telescope's SAGE Legacy Project to trace the life cycle of observable matter driving galactic evolution. The project revealed over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects. This full list, maintained by the National Aeronautics and Space Administration and last updated in March 2026, contains all extracted sources, including potential spurious ones.
