哈勃太空望远镜
Hi, Mars! 👋 In Hubble's 12th year, the telescope got a great look of the Red Planet when it was 43 million miles from Earth – the closest it'd been since 1988. This view shows frosty, white water-ice clouds and a large amount of swirling orange dust storms. A large storm rages high above the northern polar cap (top of the image), with a smaller one nearby. Another large dust storm can be seen in the giant Hellas impact basin, in the lower right of the image. We're sharing one outstanding image from each year of Hubble’s mission to celebrate its upcoming 35th birthday – counting down to a new series of anniversary images! Stay tuned for more, and get caught up at the link in our bio! Image description: The planet Mars appears with icy, white polar caps and a large swathe of rusty red desert. Dark brown dust is seen throughout the planet's surface. Image credit: NASA and The Hubble Heritage Team (STScI/AURA); Acknowledgment: J. Bell (Cornell U.), P. James (U. Toledo), M. Wolff (SSI), A.
