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.

long-proposed method of searching for extrasolar planets has finally discovered one — a body six times heavier than Jupiter that orbits a dwarf star 20 light-years from Earth.

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 ...

Astrometry — mapping the locations and movements of celestial objects — was once a central concern in astronomy, with roots going back to ancient Babylon and China.

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 ...

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, anduntil now, has failed to ...

Combined with astrometry measurements that could reveal hundreds of rocky exoplanets in neighboring systems, astronomers could be on the verge of finding life beyond Earth.

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

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