Planck Data Release 2 contains catalogs of galaxy cluster candidates detected via the Sunyaev-Zel'dovich effect. The data includes results from three independent detection pipelines, with the main catalog providing coordinates, signal-to-noise ratios, and external validation information. The National Aeronautics and Space Administration released this component of the Planck mission data.
Planck Data Release 2 contains a union catalog of galaxy clusters detected through their Sunyaev-Zel'dovich effect signature. Three independent detection pipelines—MMF1, MMF3, and PowellSnakes—were used to create candidate lists, with the main catalog providing coordinates, signal-to-noise ratios, and external validation details. This dataset was released by the National Aeronautics and Space Administration and last updated in March 2026.
A union catalog of galaxy clusters detected via the Sunyaev-Zeldovich effect, released as part of Planck Data Release 2. The list includes coordinates, signal-to-noise ratios, and external validation information like redshifts. It combines results from three independent detection pipelines: MMF1, MMF3, and PowellSnakes.
Planck Data Release 2 includes catalogs of galaxy clusters detected via the Sunyaev-Zel'dovich effect. The data are the union of candidate sources from three independent detection pipelines: MMF1, MMF3, and PowellSnakes. The catalogs provide coordinates, signal-to-noise ratios, and external validation information including redshifts where available.
Drastic changes in ideas of the age of marine Tertiary deposits in Australia have been necessary in recent years. The dataset, from Geoscience Australia Data, documents these revisions, including the recognition of Eocene deposits over a wide area in south-eastern Australia based on detailed mapping and microfauna investigation. The discovery of the Eocene foraminiferal genus Hantkenina at localities like Bird Rock, Torquay, has been a key factor in reclassifying beds from Upper Oligocene or Miocene to Eocene.
A 1.5 KB dataset published by Tianai Fan in April 2026, detailing a series of novel Amino Acid–based PROTACs (AATacs) developed for antiviral research. The data describes compounds, including the representative compound N-6, designed to degrade viral polymerase via host E3 ligases. It includes results from in vitro and in vivo studies, such as potency measurements and mouse survival rates.
188 active galactic nuclei (AGN) were identified from 497 hard X-ray sources in 20 Chandra fields. The data was created by NASA HEASARC in March 2007 based on the CDS table J/ApJ/618/123. The sample is based on X-ray and optical analysis to study sources responsible for the cosmic X-ray background.

From 2014-01 21 to 2014-11-18, the Rosetta orbiter collected Radio Science data during its PRELANDING phase at comet 67P. The dataset includes a specific Global Gravity measurement on 2014-08-31 from 12:31:00.000 to 17:51:40.500. It was produced by the National Aeronautics and Space Administration and last updated on the platform in 2026.
Comet 67P/Churyumov–Gerasimenko gravity data collected by the Rosetta spacecraft's Radio Science Investigation (RSI) instrument. The dataset contains measurements from the ROSETTA EXTENSION 1 mission phase, covering a specific observation period on 2016-02-02. It was published by the National Aeronautics and Space Administration (NASA) and last updated on the datagov platform in April 2026.
Global gravity measurements at comet 67P/Churyumov–Gerasimenko collected by the Rosetta spacecraft's Radio Science Investigation (RSI) instrument. The data covers a specific observation period from 2014-11-03T08:39:45.000 to 2014-11-03T11:40:02.500 during the pre-landing phase of the mission, which spanned from 2014-01-21 to 2014-11 -18. This dataset is provided by the National Aeronautics and Space Administration (NASA).
Standard Radiation Environment Monitor (SREM) instrument count rates and standard deviations from the Rosetta spacecraft orbiting comet 67P/Churyumov-Gerasimenko.

A dataset of differentially accumulated metabolites in Castanea mollissima (Chinese chestnut) leaves, comparing cultivars with varying resistance to the pest Oligonychus ununguis. The dataset was authored by Xinfang Zhang and is available under a CC-BY-4.0 license. It was last updated on May 15, 2026.
Partial spectral data plots from S. Sawyer's 1991 PhD thesis, 'A High Resolution Spectroscopic Survey of Low Albedo Main Belt Asteroids'.

A catalog of X-ray point sources detected in a deep XMM-Newton observation of the Fornax dwarf spheroidal galaxy. The table was created by NASA's HEASARC in February 2013 based on results published in the Astronomy & Astrophysics journal. It includes sources likely to be background active galactic nuclei, potential associations with a variable star and globular clusters, and constraints on accretion parameters for a putative intermediate-mass black hole.
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. This catalog from NASA HEASARC lists planned and validated observations from the telescope, which operates in the 3 to 79 keV energy band. The table is automatically updated and includes information on observation status and public data availability.
NASA HEASARC provides FITS lightcurves from the A detector of the GCXSE experiment aboard the OSO-8 satellite, which operated from June 1975 to September 1978. The A detector collected data in the 2-60 keV energy band, viewing portions of the sky perpendicular to the earth-sun line. This data originates from a non-solar objective instrument mounted on the spacecraft's rotating wheel section.
GLIMPSE3D is a Galactic plane mapping project using the Spitzer Space Telescope Infrared Array Camera (IRAC). The More Reliable Archive provides higher-reliability point sources from the single-visit epoch 2, requiring two detections in adjacent bands. The data was produced by the National Aeronautics and Space Administration and was last updated on 2026-03-13.
