Observations made of galaxy clusters ... 5% of the cluster's total mass. An estimated 80% is thought to be invisible dark matter, whose gravitational pull binds the entire structure together.

Using NASA's Chandra and ESA's XMM-Newton spacecraft, an international team of astronomers have performed X-ray observations of a nearby low-mass galaxy cluster designated PSZ2 G181.06+48.47.

But astronomers previously discovered that the core of the Phoenix cluster appeared surprisingly bright, and the central galaxy seemed to be churning out stars at an extremely vigorous rate.
