Ripples in the oldest known spiral galaxy may shed light on the origins of our Milky Way

Observations have revealed the first-ever seismic waves seen in an ancient galaxy, possibly offering new insight into the origins of our very own Milky Way

The galaxy, known as BRI 1335-0417, is more than 12 billion years old, making it the oldest and farthest known spiral galaxy in our universe. Using the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope in Chile, researchers studied the motion of gas around the galaxy and, in turn, captured the formation of a seismic wave. Such phenomena has never been observed before in such an early galaxy, according to a statement from the Australian National University.
