The first VERA Astrometry Catalog was published this year and includes data for 99 objects. Positioning indicates that Earth orbits the Galactic Center, where the black hole is located, at 227 km/s.

Researchers have previously used astrometry to measure the precise mass of planets found with the wobble method, but this is the first time the technique has been used to discover an extrasolar ...

Astrometry and Photometry. When not performing OSETI observations, appropriately trained observers can make precise measurements of the position and magnitude of recently discovered or poorly observed ...

A new method for directly detecting ultralight dark matter is proposed, utilizing precision astrometry to measure subtle, distance-dependent fluctuations in spacetime caused by these particles.

The relative astrometry for CHES can accurately measure micro-arcsecond level angular separation between one target star and 6-8 reference stars.

Astrometry wasfirst attempted 50 years ago to search for planets outside our solar system, butthe method requires very precise measurements over long periods of time, ...

Astrometry, says Lindegren, “was not regarded as a field that would offer any great prospects for young scientists”. He eventually gave up on repairing the telescope, but never abandoned the ...

The planet, HIP 99770 b, was discovered by teaming up the Gaia satellite with a direct imaging instrument to actually "see" the planet.
