Abstract The Asteroid Terrestrial-impact Last Alert System (ATLAS) observes most of the sky
every night in search of dangerous asteroids. Its data are also used to search for photometric …

Abstract Between 1997 June and 2001 February the Two Micron All Sky Survey (2MASS)
collected 25.4 Tbytes of raw imaging data covering 99.998% of the celestial sphere in the …

Context. The first release of astrometric data from Gaia will contain the mean stellar positions
and magnitudes from the first year of observations, and proper motions from the combination …

Abstract The Washington Double Star Catalog (WDS), maintained by the US Naval
Observatory, is the world's principal database of astrometric double and multiple star …

We describe the calibration status and data products pertaining to the GR2 and GR3 data
releases of the Galaxy Evolution Explorer (GALEX). These releases have identical pipeline …

Understanding the formation and evolution of our Galaxy requires accurate distances, ages,
and chemistry for large populations of field stars. Here, we present several updates to our …

Context. Gaia Data Release 1 (DR1) contains astrometric results for more than 1 billion stars
brighter than magnitude 20.7 based on observations collected by the Gaia satellite during …

Astrometry in the 1960s and 1970s was still entirely ground-based, and all too often seen
(and experienced by very few) as a rather tedious, time-consuming technique that no longer …

We use milli-arcsecond accuracy astrometry (proper motions and parallaxes) from
Hipparcos and from radio observations to retrace the orbits of 56 runaway stars and nine …
