Measurements of unprecedented detail returned by Japan s core lies a supermassive black hole activated by infalling matter. Glowing filaments extending from the galaxy trace bubbles of gas blown violently outward by the black hole. Despite this activity, Hitomi measurements show that hot cluster gas in the vicinity is moving at cosmically modest speeds. Copyright © 2008 by R.

This image is 39 arcminutes across and 29 arcminutes tall. The galaxy at the core of the cluster, NGC 1275, is located near the center.

Filaments of glowing gas, some reaching lengths of 20,000 light-years, extend from the central regions of the galaxy, where an active supermassive black hole resides. Also known by its radio designation Perseus A, NGC 1275 is over 100,000 light-years across and lies about 240 million light-years away.Credit: NASA/ESA/Hubble Legacy Archive and Al Kelly
