Galaxies leave behind record-breaking fiery tail after cluster plunge.

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.

Record-breaking galactic tail discovered near doomed galaxy group.

Astronomers have discovered a gas tail stretching over a million light-years long behind galaxy group NGC 4839, which is merging with the much larger Coma Cluster. Using X-ray data from NASA's Chandra X-ray Observatory and optical data from the Sloan Digital Sky Survey, scientists measured the tail as NGC 4839 moved through the Coma Cluster. The tail is the longest such structure ever observed and is burning especially bright, giving astronomers a rare opportunity to study it in more detail and learn more about the mechanics of how galaxy clusters merge.
