Large X-shaped structure spotted in the center of our galaxy
X literally marks the spot in the center of the Milky Way, a phenomenon that offers clues about the galaxy’s formation.
It seems like a cliche, but “X” actually does mark the spot in the center of our galaxy. Researchers working with data from the Wide-field Infrared Survey Explorer (WISE) mission have confirmed the existence of a strange X-shaped structure at the heart of the Milky Way, reports NASA.
The enormous X is made from a bulge of stars that are moving around the galactic center, perpendicular to the plane of the galaxy, and in and out radially.
