肉眼

The smash-up between M86 and NGC4438 had not been suspected before, and may explain why M86, which is visible to the naked eye, is unable to give birth to new stars.

以前，天文学家们不曾猜想到星系 M86 和 NGC4438之间的碰撞。然而，那次碰撞可以解释为什么星系 M86中不能产生新恒星。 M86是用肉眼可以看到的一个星系。

" Colloid : Substance consisting of particle s that, although too tiny to be seen with the unaided eye (typically 1 nanometre to 10 micrometres), are substantially larger than atoms and ordinary molecules and that are dispersed in a continuous phase."

胶体：由比原子或普通分子大得多，但远小于肉眼可见的微粒组成的物质。这种粒子的大小大约在10-7～10-3公分，并且以各种方式连接或键合在一起。
