Astronomers have been able to take the temperature of planets around other stars, first with telescopes in space but more recently with ground-based instruments, as my collaborators and I have done.

天文学家已能够对其他恒星周围的行星测量温度，起初用的是太空望远镜但近来用的是地面仪器设备，就像我的合作者与我所做的那样。

In addition to those observations, an array of telescopes and cameras on Earth and in space will be watching to grab images.

除了进行这些观察以外，地球和太空中的一系列望远镜和摄像机都将进行观测，抓拍图像。

Until now, scientists have only been able to analyse the atmospheres of such distant worlds using the Hubble and Spitzer space telescopes, which are in orbit around the Earth.

到目前为止，科学家仅能利用环绕地球飞行的哈勃或斯皮策太空望远镜，来分析如此遥远星球的大气层成分。

The work, which is described in the journal Nature, actually draws on observations made by several astronomical facilities, including the Keck and James Clerk Maxwell telescopes in Hawaii and the Hubble Space Telescope in orbit around the Earth.

Telescopes, including those in space, have revealed more than 100 planets in the last decade alone.

Yeomans and colleagues are using telescopes on the ground and in space to nail down the precise orbit of objects that might threaten Earth and predict whether the planet could be hit.
