How About a Hug?! Nearby Galaxy Cluster Has Giant Plasma Arms

Enormous arms of hot gas have been revealed in the Coma galaxy cluster in data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton.
A nearby cluster of galaxies is reaching out into the universe with colossal plasma arms — galactic tentacles so long they are nearly five times the width of the Milky Way, astronomers say.
I chose this article because I think it is important to know about this, and it looked very interesting when I started reaserching it. It tell about how astronomers have discovered titanic arms of plasma glowing brightly, with X-rays emanating from the core of the Coma Cluster. Maybe in the future this will help us know more about this. And it will be interesting to be studying it in class.
This article is important because this titanic arms can reach up to about 490,000 light-years long and 80,000 light-years wide, and researchers estimate these arms can get up to 40 billion times the mass of the sun. Also the discovery suggests the cores of turbulent galaxy clusters may be much less chaotic than scientists previously thought.
