VG1-S-PRA-3-RDR-LOWBAND-6SEC-V1.0 contains calibrated low-frequency radio astronomy data from the Voyager 1 spacecraft's Planetary Radio Astronomy (PRA) instrument during its Saturn encounter. The dataset covers the period from 1980-08 22 to 1980-12-14 and provides the highest time resolution possible during normal operations, with sweeps through 70 low-band channels every 6 seconds. Data are provided in ASCII format with calibrated power measurements in millibels.
HST's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) provides imaging and spectroscopy in the 0.8-2.5 micron wavelength range. It offers broad, medium, and narrow band filters, imaging polarimetry, coronography, and slitless grism spectroscopy via three independent cameras. The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
The Spitzer Mapping of the Outer Galaxy (SMOG) project mapped a 21 square degree area of the Outer Galaxy using the Spitzer Space Telescope's IRAC and MIPS instruments. The data have been processed by the Wisconsin GLIMPSE IRAC pipeline, resulting in a point source Archive. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
The Space Telescope Imaging Spectrograph (STIS) was installed on the Hubble Space Telescope on February 14, 1997. It provides spectra and images at ultraviolet and visible wavelengths, probing the universe from our solar system out to cosmological distances. The data is provided by the National Aeronautics and Space Administration.
The High Speed Photometer (HSP) was an original instrument on the Hubble Space Telescope. It was designed to make rapid photometric observations of astrophysical sources from the near ultraviolet to the visible. The instrument was removed from the telescope during the First Servicing Mission in December 1993.
A 21 square degree area of the Outer Galaxy was mapped by the Spitzer Space Telescope's IRAC and MIPS instruments. The data were processed by the Wisconsin GLIMPSE IRAC pipeline to produce two types of source lists: a high-reliability point source Catalog and a more complete point source Archive. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
A modified version of the Skiff Spectral catalog, containing roughly 450,000 stellar targets. The table includes standard spectral classifications and their encoded values as defined in an IVOA note. The catalog is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
NASA's Voyager 2 Planetary Radio Astronomy (PRA) instrument collected this dataset during the Saturn encounter from 1981-06 05 to 1981-09-28. It contains calibrated low-frequency radio receiver band data at the highest 6-second time resolution possible during normal operations, packaged into 48-second spacecraft major frame records. The data are provided in ASCII format with power measurements in millibels.
One-minute resolution electron and proton flux spectra from the STEREO-B spacecraft's IMPACT Solar Electron Proton Telescope (SEPT). The data consist of fluxes from 32 energy bands spanning ~20 keV to 2000 keV for electrons and 7000 keV for protons, measured in four directions. The dataset is produced by the National Aeronautics and Space Administration.
Spin-averaged coincidence fluxes for protons and helium nuclei recorded at a 10-minute cadence by the Ulysses spacecraft's COSPIN Anisotropy Telescopes. The data originates from NASA and includes measurements from two differently oriented telescopes (AT1 and AT2). The dataset was last updated on March 13, 2026.
Spin-averaged coincidence counting rates for ions and electrons from the Ulysses spacecraft's High Energy Telescope. The data is provided as 10-minute averages by NASA. The dataset was last updated on March 13, 2026.
Daily average fluxes of protons, alpha particles, and electrons across multiple energy channels, measured by the COSPIN/KET instrument on the Ulysses spacecraft. The data includes Poisson uncertainties for each flux measurement. The dataset is provided by the National Aeronautics and Space Administration.
NASA's Helios 1 E7 dataset contains hourly averaged fluxes of protons measured by the GSFC Galactic and Solar Cosmic Ray experiment. Each record includes date, time, and flux values with statistical errors for proton energy ranges of 3.3-21.6 MeV, 21.6-57 MeV, and above 57 MeV. The data was last updated on 2026-03-13.
Hourly averaged proton fluxes from the GSFC Galactic and Solar Cosmic Ray experiment aboard the Helios 2 spacecraft. The data includes flux values and statistical errors for three distinct proton energy ranges: 3.3-21.6 MeV, 21.6-57 MeV, and above 57 MeV. This dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
An ASCII file contains 25 abundance ratios for pairs of chemical elements derived from cosmic ray observations. The ratios are based on data from the University of Chicago experiment on the ISEE 3 satellite, collected between 1978 and 1981 for particles with energies of approximately 50-500 MeV/n. Each ratio is linked to its source publication within the file.
Ten-minute average counting rates for ions and electrons from the Ulysses spacecraft's COSPIN High Energy Telescope. The data provide a measure of particle arrival direction anisotropy in the spacecraft spin plane and were produced by the National Aeronautics and Space Administration. The dataset was last updated in March 2026.
Daily average fluxes of protons and helium nuclei from the Ulysses spacecraft's COSPIN High Energy Telescope. The data covers two energy ranges, 39-70 MeV/n and 71-94 MeV/n, spanning from day 296 of 1990 through day 181 of 2009. This dataset was produced by the National Aeronautics and Space Administration.
NASA's Ulysses spacecraft recorded energetic particle fluxes from the Sun and interstellar space. The High Flux Telescope measured spin-averaged and sectored counting rates for protons and heavier nuclei. Data is aggregated into 10-minute average nominal fluxes.
Voyager 1's Planetary Radio Astronomy instrument captured calibrated low-frequency radio emissions from Saturn during its 1980 encounter.
