EMSS Antennas is part of a new scientific publication in the journal Nature: Giant balloon structures found at the center of the Milky Way.

A pair of towering, hourglass-like balloons have been discovered at the heart of our home galaxy, the Milky Way, according to a new study. They are some of the largest features ever observed at the galactic center and researchers were able to detect them because they’re emitting radio waves.
