Dark energy causes the acceleration by pushing space itself apart, altering the distances to the supernovas as it does so.

暗能通过推进空间分离而加速，因此就像所观察到的那样加大了距离。

Any missions hoping to go farther will need a means of acceleration that can get the spacecraft to the edge of explored space faster—before it has depleted its radioactive power source.

故而，任何更深空的宇宙探索都需要寻找技术途径来加速航天器，以便在放射性能源耗尽之前到达星系边缘。

Japanese space agency (Jaxa) scientists want to detect a measurable acceleration in the spacecraft as photons - the particles of light - from the Sun fall on the roughly 200-sq-m, ultra-thin sheet.

But analysis of the motion of Ulysses, another space probe, has shown that it, too, is affected by the mysterious acceleration.
