This data was produced by the National Aeronautics and Space Administration (NASA).
The Galactic Plane survey covers 170 square degrees, contiguous over -10.5 ≤ l ≤ 90.5, |b| ≤ 0.5, with additional targeted regions in the outer Galaxy. It contains approximately 8,400 sources detected at 1.1 mm wavelength, with an rms noise level of 30 to 60 mJy beam-1. The dataset was produced by the National Aeronautics and Space Administration and last updated in March 2026.
The Galactic plane from |l| = 10◦ to 65◦ and |b| < 1◦, with vertical extensions up to |b| < 4.2◦ in the galactic center, is mapped by this dataset. It contains point sources with a signal-to-noise > 5 in at least one infrared band from the Spitzer Space Telescope IRAC instrument, with photometric uncertainty typically under 0.3 magnitudes. The data was produced by the National Aeronautics and Space Administration and was last updated on March 13, 2026.
An archive of infrared point source observations from the Spitzer Space Telescope's Deep GLIMPSE project. The data maps 125 degrees of Galactic longitude in the Far Outer Galaxy using two IRAC bands at 3.6 and 4.5 μm. It was produced by NASA as part of a Warm Mission Spitzer Cycle 8 Exploration Science Program.
GLIMPSE3D is a large-area infrared mapping project of the Galactic plane using the Spitzer Space Telescope. The Archive consists of point sources with a signal-to-noise ratio greater than 5 in at least one band, with photometric uncertainty typically below 0.3 magnitudes. This dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
NASA HEASARC provides a table from a 2010 spectroscopic study of 1080 nearby active M dwarfs, selected by correlating the 2MASS and ROSAT catalogs. The dataset includes derived spectral types, distances, H-alpha emission line measurements, X-ray luminosities, and tangential velocities for a subset of stars. Spectral types range from K5 to M6, with nearly half of the stars located within 50 parsecs.
A galactic catalog of 760 O-type stars compiled from literature sources. The table is based on the Catalog of Galactic O-Type Stars (Garmany, Conti, and Chiosi 1982) and includes designations, spectral types, UBV photometry, cluster memberships, positions, and source references. NASA HEASARC provided the service, updating positions via SIMBAD and removing or modifying erroneous entries.
The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSEII) imaged longitudes ±10° of the central region of the Galaxy. The dataset contains point source observations from two epochs in September 2005 and April 2006, with photometric uncertainty typically below 0.3 magnitudes. It was produced by the National Aeronautics and Space Administration.
227 Galactic Wolf-Rayet stars are cataloged with improved coordinates, spectral types, and photometry. The catalog, created by NASA HEASARC in April 2001, adds 71 new stars compared to the previous version and includes data on binarity, wind velocities, and associations with nebulae. Information on heliocentric and galactocentric distances and source references is provided.
72,758 compact radio sources at 1420 MHz were cataloged from the Canadian Galactic Plane Survey (CGPS) covering 1,464 square degrees of the northern Galactic plane. The catalog, created by NASA HEASARC in June 2017, includes linear polarization properties for 12,368 sources and identifies 146 candidate variable and 13 candidate transient sources. Observations were carried out by the Dominion Radio Astrophysical Observatory Synthesis Telescope in three phases from 1995 to 2009.
Dinoflagellate cyst data from the central west Murray Basin in Australia. The dataset, published by the Australian Ocean Data Network, offers a method for distinguishing Late Miocene-Early Pliocene Bookpurnong beds from older, lithologically similar sediments. It lists species diagnostic for specific geological formations, such as Melitasphaeridium aequabile for the Bookpurnong beds and Apteodinium australiense for the older Murray Group correlatives.
GLIMPSE3D is a large-area mapping project of the Galactic plane using the Spitzer Space Telescope Infrared Array Camera. The GLIMPSE3D Archive consists of point sources with a signal-to-noise > 5 in at least one band, with photometric uncertainty typically < 0.3 magnitudes. It is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
Three field surveys in Darwin Harbour, Australia, studied the effect of sewage-derived nutrient loads on biogeochemical processes in mangrove-lined tidal creeks. The dataset, sourced from the Australian Ocean Data Network, compares water quality, sediment composition, and metabolic rates across three creeks with varying pollution levels. It was last updated on 2026-04-10.
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 four IRAC channels (3-8 microns) and the 24-micron MIPS channel. The source list prioritizes reliability over completeness, meaning it is not complete at any flux density.
A catalog of high-reliability infrared point sources from the Spitzer Space Telescope's Deep GLIMPSE survey. The data maps 125 degrees of Galactic longitude on the Far Side of the Galaxy, covering longitudes l=265°-350° and 25°-65° with a latitude width of about 2.1°. It was produced by NASA as part of the Warm Mission Spitzer Cycle 8 Exploration Science Program.
GLIMPSE II Epoch2 More Reliable Archive provides higher-reliability infrared point source data from a survey of the central region of the Milky Way. The National Aeronautics and Space Administration collected this data using two-epoch observations in September 2005 and April 2006. Sources in this archive meet stringent criteria requiring two detections in adjacent infrared bands, including the 2MASS Ks band.
44 studies from 28 countries provide global prevalence estimates for Neuromyelitis Optica Spectrum Disorder (NMOSD). This supplementary material includes results from a systematic review, meta-analysis, and a new regional study in Rio de Janeiro, Brazil. The work was authored by figshare admin karger and last updated in April 2026.
24-hour-averaged count rates from the University of Iowa Geiger Tube Telescope experiment on the Pioneer 10 spacecraft, corrected for RTG and temperature effects. The data set holds rates for 8 sensors or multi-sensor coincidence modes, measuring directional and omnidirectional fluxes of electrons and protons across multiple energy ranges. Data were provided to NSSDC on a VMS-binary-formatted CD-ROM and converted to ASCII by GSFC/SPDF in 2010.
NASA's Pioneer 11 spacecraft collected this data via the University of Iowa's Geiger Tube Telescope experiment. The dataset contains 24-hour-averaged count rates for 8 sensors and multi-sensor coincidence modes, measuring fluxes of electrons and protons across specific energy ranges. Data were corrected for RTG and temperature effects, converted to ASCII in 2010, and are accessible as a single 9-MB file.
Voyager 1's Cosmic Ray Subsystem (CRS) experiment measured energetic particles from 1977 onward. The Level H3 daily data likely contains proton and helium energy fluxes from the spacecraft's journey through the solar system and beyond. NASA's instrument was designed to measure cosmic ray nuclei from hydrogen through iron over an energy range from approximately 1 to 500 MeV/nuc.
