Newly Discovered Galaxy
Astronomers recently discovered a new galaxy cluster. Its color indicates that it should be dead – “red and dead” – but the center is a hot blue, like baby stars. They say this galaxy has come alive again, so to speak.
Galaxies this old are far past star-producing age, yet this one is spewing out stars thousands of times faster than other clusters like it.
It has been nicknamed the Phoenix Cluster, after the bird who rose from the ashes.
All galaxies should come back to life like this, theoretically. What prevents this is a massive black hole in the center of each galaxy. The gases that are emitted from black holes keep dying galaxies from restarting again, according to the articles.
For some reason, this galaxy’s black hole doesn’t have the same death-producing power – so its center is blue like a newborn galaxy.
