Galaxies leave behind record-breaking fiery tail after cluster plunge.
TL;DR Summary
A large cluster of galaxies is consuming a smaller galactic grouping, causing it to emit a record-breaking tail of hot gas. The tail is 1.5 million light-years-long, making it the largest tendril of gas ever seen emerging from a galactic group. The absorption of NGC 4839 by the Coma cluster could help astronomers understand the processes galaxy groups undergo as they merge. The brightness of the tail offers astronomers a unique opportunity to study the physics at play in such events.
