A high-resolution image of the galactic core reveals an abundance of highly energetic events, some observed for the first time: remnants of supernova (bubbles of gas and matter ejected during the explosive death of stars), star-forming regions, mysterious long, bright filaments, as well as the turbulent region around Sagittarius A*, the supermassive black hole at the center of the galaxy (<em>The Astrophysical Journal<\/em>, February 1).
