Palynological analysis of the Oakvale-1 corehole in the western Murray Basin shows diverse and well-preserved assemblages of spores, pollen, and dinoflagellates throughout the marine Oligocene-Miocene sequence. Pollen of Nothofagus is present throughout, with Nothofagidites emarcidus the most common form, and Myrtaceous pollen is abundant. The site provides good fossil records for extant Australian taxa like Acacia pollen from the late Oligocene and the first Australian fossil record for pollen of Utricularia and Gardenia.
Calcareous nannofossil assemblages from the Challenger No. 1 well offshore Perth Basin revise the age of the Challenger Formation type section. The data likely contains stratigraphic records from the Late Cretaceous through the Palaeogene, including Middle Eocene-Oligocene sediments. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-04-16.
Data Sheet 1_PHGDH-mediated serine synthesis reduces oligodendrocyte death by sustaining GSH and NADPH levels after brain ischemia.pdf is a 404.5 KB PDF file published on figshare by Zhaolong Zhang under a CC-BY-4.0 license. The document contains research data and results from a study investigating the role of the PHGDH enzyme in protecting oligodendrocytes from ischemic injury. The dataset was last updated on 2026-04-15.
NASA's Ulysses spacecraft COSPIN-High Energy Telescope dataset provides full-resolution pulse-height analysis (PHA) events for cosmic rays and solar energetic particles. Each file contains detailed information for every non-zero PHA event, with 54 columns per event, including raw channels, energy deposits, and derived particle charge and trajectory. The data is organized in daily files from at least 1990 onward, with a priority system favoring the capture of rare heavy nuclei.
2,244 objects detected in the near-ultraviolet by the Ultraviolet Imaging Telescope during the Astro-1 Space Shuttle mission. The catalog includes near-UV magnitudes and cross-identified optical colors, with 88% of objects having proposed optical identifications, most of which are stars. NASA HEASARC created this database in November 2000 based on source material from the CDS.
NASA HEASARC provides a catalog of 304 X-ray point sources detected in the Trifid Nebula by the Chandra X-ray Observatory. The observation was conducted on 2002 June 13 for 16 hours using the ACIS-I detector. This table was created in January 2007 based on data from the CDS.
The Spitzer Extragalactic Representative Volume Survey (SERVS) provides deep infrared observations of five extragalactic fields. This catalog for the ELAIS-N1 field contains matched 3.6 and 4.5 micron sources with a high reliability threshold of >99.9%, requiring detection in both bands with a >10-sigma coverage-weighted signal-to-noise ratio in one. The data was produced by NASA's Spitzer Space Telescope Exploration Science program.
SERVS provides deep infrared observations at 3.6 and 4.5 microns across five extragalactic fields. The catalog contains matched, high-reliability (>99.9%) objects detected in both bands with a signal-to-noise ratio greater than 10-sigma. This data was produced by NASA's Spitzer Space Telescope Exploration Science program.
269,358 point sources from the Spitzer Space Telescope survey of the Taurus Molecular Clouds. The catalog provides flux densities in the 3.6, 4.5, 5.8, 8.0, and 24 micron bands, with some sources also having 70 micron data. It was produced by NASA as part of the Taurus Spitzer Legacy project, with the last metadata update recorded in March 2026.
11.5 square degrees of sky near the South Ecliptic Pole were imaged at 24 and 70 Ξm wavelengths by NASA's Spitzer Space Telescope. The catalog contains point sources detected with a signal-to-noise ratio greater than 6, with 93% considered reliable based on reduced chi-squared values. This data was collected to complement sub-millimeter observations from the BLAST telescope and the Herschel Multi-tiered Extragalactic Survey.
A southern Galactic Plane region between 245 and 355 degrees longitude and within ~1.5 degrees latitude is covered by this catalog of supernova remnants. It contains 93 total objects, including 57 known, 18 newly discovered, 16 possible, and 2 reclassified remnants, identified from 0.843 GHz radio observations. The catalog was created by NASA's HEASARC in March 2007 based on data from the Molonglo Observatory Synthesis Telescope.
2151 high-redshift source candidates identified from 48 months of Planck satellite data combined with IRAS data. The list targets point sources in the cleanest 26% of the sky exhibiting a submillimeter excess. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
Spitzer Extragalactic Representative Volume Survey (SERVS) provides deep infrared observations of five extragalactic fields. The ELAIS-S1 2-band catalog contains matched 3.6 and 4.5 micron sources with a stated reliability greater than 99.9%. This catalog was produced by NASA and was last updated on 2026-03-13.
374 radio sources were observed in a deep field search for fossil radio lobes, with 317 sources detected at a minimum of three frequencies. The catalog, created by NASA HEASARC in March 2012, is based on Giant Metrewave Radio Telescope observations from 2005 and 2008. Almost all sources show a straight spectrum with a median spectral index of ~0.8, and 14 sources were identified with very steep spectra (alpha >~ 1.3).
The Washington Double Star Catalog (WDS) is the world's principal database of astrometric double and multiple star information, maintained by the United States Naval Observatory (USNO). It contains positions, discoverer designations, epochs, position angles, separations, magnitudes, and spectral types for the components of close to 100,000 systems based on approximately 600,000 means. The catalog is updated weekly by NASA HEASARC and is intended to contain all known visual double stars for which at least one differential measure has been published.
West-central Mediterranean Sea surface oligotrophic water measurements were collected in 2008. The dataset is provided by the National Aeronautics and Space Administration (NASA). It is available in BIN and ISO file formats.
Dinoflagellate microfossils provide a reliable method for distinguishing Late Miocene-Early Pliocene sediments from older formations in the Murray Basin. The dataset, published by Geoscience Australia, identifies species like Melitasphaeridium aequabile and Tuberculodinium vancampoae as diagnostic for the Bookpurnong Beds. It contrasts these with species indicative of older units such as the Geera Clay and Winnambool Formation.
The Indo-Pacific region provides data from three marginal-marine sections and deep oceanic sediments. The dataset likely contains biostratigraphic records of nannofossils and planktic foraminifera, focusing on species like Globigerinoides quadrilobatus primordius and Sphenolithus ciperoensis. It was aggregated by the Australian Ocean Data Network and last updated in April 2026.
