First Hyper Velocity Star Cluster Observed

I thought this was pretty neat:

From the abstract:
We report the discovery of an object near M87 in the Virgo Cluster with an extraordinary blueshift of -1025 km/s, offset from the systemic velocity by >2300 km/s. Evaluation of photometric and spectroscopic data provides strong evidence that this object is a distant massive globular cluster, which we call HVGC-1 in analogy to Galactic hypervelocity stars.

A story on this discovery appeared two months ago: Physics Forums.
