Scientists have observed BZ with ground-based telescopes in the American states of Hawaii and Arizona. They said BZ apparently left its home star system when the star system interacted with other systems in a tight fitting star cluster.

在美国夏威夷州和亚利桑那州，科学家们用地面望远镜观测到了BZ。他们说，很明显，BZ所在星系与其他星系的星团相互作用后，BZ离开了它所在星系。
