Astronomers Unveil High-Speed Galactic Collisions with New Telescope

Scientists have observed a dramatic collision of four galaxies in Stephan's Quintet, located 290 million light-years from Earth. The interaction, involving a galaxy moving at 3.2 million km/h, creates a massive X-ray shock front, providing insights into how galaxies merge and evolve. Using the WEAVE spectrograph, researchers discovered that the shock front affects gas in different ways, revealing new details about the dynamics of galactic collisions. This research enhances understanding of galaxy formation and evolution, with findings published in the Monthly Notices of the Royal Astronomical Society.

Galactic Collision Unleashes Powerful Shockwaves Across the Cosmos

The WEAVE spectrograph on the William Herschel Telescope has provided new insights into the dual nature of shock waves in Stephan's Quintet, a group of five galaxies. Led by Dr. Marina Arnaudova, the study reveals that the shock, caused by a high-speed collision of galaxy NGC 7318b, behaves differently in cold and hot gas regions. In cold gas, the shock travels at hypersonic speeds, ionizing the gas, while in hot gas, it weakens and compresses, emitting radio waves. This research highlights WEAVE's potential to enhance our understanding of galactic interactions.

Astronomers Capture 2 Million MPH Galactic Collision with Sonic Boom

Astronomers have observed a powerful shock wave in Stephan's Quintet, caused by the galaxy NGC 7318b colliding with its neighbors at 2 million mph. This cosmic event, akin to a sonic boom, has energized plasma and possibly triggered star formation. The study, using the WEAVE spectrograph, aims to provide insights into galaxy interactions and cosmic history, with findings published in the Monthly Notices of the Royal Astronomical Society.

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.
