Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy.

- a measurement that could help determine if magnetars are the sources of the long-mysterious Fast Radio Bursts (FRBs).

A magnetar called XTE J1810-197, discovered in 2003, was the first of only six such objects found to emit radio pulses. It did so from 2003 to 2008, then ceased for a decade. In December of 2018, it resumed emitting bright radio pulses.

"This is the first parallax measurement for a magnetar, and shows that it is among the closest magnetars known—at about 8100 light-years—making it a prime target for future study."
