Galactic Collision at 2 Million MPH Unveils Cosmic Chaos

Astronomers have observed a dramatic 2-million-mile-per-hour collision involving the galaxy NGC 7318b at Stephan's Quintet, a site known for previous galactic smash-ups. This event, captured using the WEAVE spectrograph and data from the James Webb Space Telescope and LOFAR, has reawakened the dynamic activity in the region, creating a powerful shockwave. The collision provides insights into the formation and evolution of galaxies, with the findings published in the Monthly Notices of the Royal Astronomical Society.
