The ground under our feet is constantly moving, and to measure these movements, researchers have turned to an unlikely helper: quasars that are millions of light-years away.

The video highlights the importance of cross-border cooperation in radio astronomy through VLBI technology, which connects antennae across different countries to create a powerful telescope. JIVE in Europe plays a key role in...

VLBI, or Very Long Baseline Interferometry, is a technique that uses multiple radio telescopes to very precisely measure the Earth's orientation. It was originally invented back in the 1960s to take better pictures of quasars, but...

Space geodesist Chopo Ma explains the science of Very Long Baseline Interferometry (VLBI): using radio emissions from distant galaxies to create a precise reference frame for the Earth.<b<b<br/>r/>r/>

Project manager Stephen Merkowitz talks about his work with NASA's Space Geodesy Project, including a brief overview of the four fundamental techniques of space geodesy: GPS, VLBI, SLR, and DORIS.<b<b<br/>r/>r/>
