Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

Scientists also discovered a second planet, a brown dwarf orbiting another low-mass star. Gaia-5b orbits the Gaia-5 star, around 134 light-years away from Earth.

They had some help that wasn't available in 2006: the ESA's Gaia spacecraft. Gaia is our star-measuring superhero. It sits at the sun-Earth L2 point, where it measures 2 billion objects ...
