Keeping Earth safe from asteroids isn’t just spotting them – it’s also helping people understand what a high-impact probability with Earth means.

Europe compares favourably with the US on the level of space science it delivers, and Esa has sometimes “gone boldly” where even Nasa has not. Now that Esa has turned 50 years old, it’s a good time to ...

His strategy for finding new exoplanets to image is highly targeted, guided by evidence of the gravitational pull of a planet from the star’s astrometry. Of the roughly 6,000 exoplanets that have been ...

Researchers at the University of Florida recently proposed a new method for the direct detection of ultralight dark matter particles, which is based on astrometry, the precise measurement of the ...

Because Gaia precisely tracked the motion of stars -- a technique known as astrometry -- thousands of new objects are expected to be discovered in its data.

The achievement of microarcsecond relative astrometry in the near-infrared, with ground-based extremely large telescopes (ELTs) requires an extremely careful calibration strategy. In this paper we ...

The Vienna VLBI and Satellite Software (VieVS) is state-of-the-art Very Long Baseline Interferometry (VLBI) analysis software for geodesy and astrometry. VieVS has been developed at Technische ...
