Astronomers say the Planck observatory has made more than 20 detections that are brand new to science.

The European Space Agency telescope has also confirmed the existence of a further 169 galaxy clusters.

2. galaxy clusters totally freak me out ...

it's impossible to imagine the immensity of those structures!

The clusters, sighted in all directions, range out to about four billion light-years from Earth.

And here i was, this afternoon, going nuts trying to identify young globular clusters in Hubble ACS images of NGC5055. :crazy:
