Entire star cluster thrown out of its galaxy

This artist's illustration shows the hypervelocity star cluster HVGC-1 escaping from the supergiant elliptical galaxy M87. HVGC-1 is the first runaway star cluster discovered by astronomers. It is fated to drift through intergalactic space.
Galaxy M87 has thrown an entire star cluster toward us at more than 2 million mph, and it’s now on a fast journey to nowhere.
