We give continuous night and day light measurements at all natural outdoor light levels by a network of low-cost lightmeters. Developed to start simple, global continuous high...

Differences between UCAC3 and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(UCAC3) averaged over...

The Stellar content, MAss and Kinematics of Cluster Early-type Dwarf galaxies (SMAKCED_) project is a survey of 121 Virgo cluster early type galaxies. This service publishes...

This is a view of the dust maps in the five orders, generated by splitting the larger pixels from the higher orders into HEALPixes of order 10. This means, in particular, that...

This service publishes plate scans of the Palomar-Leiden Troian surveys conducted between 1960 and 1977. The surveys led to the discovery of more than 2,000 asteroids (1,800...

An optical polarimetric catalog for the Small Magelanic Cloud (SMC) is presented. It gives intrinsic and observed polarizations in the V-band for a total of 7207 stars located...

These are 1.4GHz Very Long Baseline Interferometry images of 532 radio sources with a flux density exceeding 100uJy as determined by Ibar et al. (2009, MNRAS, 397, 281),...

A web-based GUI to the infinite microlensing lightcurve.

The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...

A list of neutrino candidate events recorded by the IceCube neutrino telescope operating in a 40 string configuration between April 2008 and May 2009.

UCAC4 is a compiled, all-sky star catalog covering mainly the 8 to 16 magnitude range in a single bandpass between V and R. Positional errors are about 15 to 20 mas for stars in...

An archive of optical and near-infrared spectra of strongly lensed quasars and the lensing galaxies. The spectra are resolved to about a few Ångstroms and are flux-calibrated....

This dataset contains spectroscopic observations of 29 globular clusters in the Magellanic Clouds and the Milky Way performed with VLT/X-shooter over eight full nights.

MWSC-e14a ("MWSC extension 2014a") is a catalogue of 139 new open clusters at high Galactic latitudes (\|b\|>20 deg) including lists of candidate members. It extends the...

The Bochum Galactic Disk Survey is a project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been...

This is a catalogue of photometric redshifts of galaxies in the Stripe 82 obtained when morphology (galaxy size, ellipticity, Sérsic index, and surface brightness) are included...

Computation of Greenwich Apparent Sidereal Time, Greenwich Mean Sidereal Time, and the Earth Rotation Angle

A catalogue of 541 nearby (within 10pc of the sun) stars, brown dwarfs, and confirmed exoplanets in 336 systems, as well 21 candidates, compiled from SIMBAD and several other...

Complete Asteroid Data from the Minor Planet Center (MPC), updated once per month. The MPC operates at the Smithsonian Astrophysical Observatory under the auspices of Division...
