艾伦望远镜阵列，即在加利福尼亚为搜寻地外文明计划而建造的一组射电望远镜，将显著提高其速度以达到能够探测到那些星系的程度。

The Allen telescope Array, a cluster of radio telescopes being built in California with SETI in mind, will dramatically speed up the rate at which such systems can be explored.

除此之外，由于天文学家们如今已更容易发现新的星球，其中有更多的星球适于生存，这样搜寻地外文明计划又多了许多貌似可以达到的目标。

On top of that, as astronomers get better at discovering planets, and find more habitable ones, the number of plausible targets for SETI will increase.
