Ancient Galactic Disk Reveals Seismic Ripples: Astronomers' Groundbreaking Find

Astronomers have detected seismic ripples in the ancient galactic disk of BRI 1335-0417, the oldest and furthest known spiral galaxy in the universe. Using the ALMA telescope, researchers observed the motion of gas within the galaxy and discovered a seismic wave forming, indicating the dynamic growth of the young galaxy. The study also revealed a bar-like structure in the disk, which can disrupt gas and transport it towards the galaxy's center. These findings provide insights into how gas fuels star formation and the formation of spiral structures in early galaxies.
