Gravitational waves are ripples in the curvature of space-time produced by the motion of massive celestial objects. Gravitational waves provide a different kind of information about the universe and their measurement will lead to an entirely new type of astronomy. The quest to detect gravitational waves is entering a new era with the Laser Interferometer Space Antenna (LISA) now under development. LISA is a two billion dollar joint NASA/ESA deep space mission to build a gravitational wave observatory in space. This research will develop Australian technologies critical to the success of LISA and other future deep space missions.

引力波是大质量天体运动在时空曲率中产生的涟漪。引力波提供了关于宇宙的另一种信息，对它们的测量将导致一种全新的天文学。探测引力波的探索正在进入一个新的时代，激光干涉仪空间天线（LISA）正在开发中。LISA是一项耗资20亿美元的NASA/ESA联合深空任务，目的是在太空中建立一个引力波天文台。这项研究将开发对LISA和其他未来深空任务成功至关重要的澳大利亚技术。
