甚大望远镜拍摄的哈雷彗星

2003年3月6-8日利用4架VLT中的3架拍摄，此时彗星距离太阳28.06 AU，距离地球27.26 AU。
不过不是很清楚……

还有一张

为什么那么粗糙？？
那么多黑色暗条是什么？？

这是某见过的最帅的照片liao。。。。。。。。

[B]为什么那么粗糙？？
那么多黑色暗条是什么？？

毕竟距离太远，而且亮度太低，恐怕除了VLT，谁都拍不了……
那暗条应该是背景恒星，为了追踪彗星，恒星拉成了线。
简要说明：PR Photo 27c/03 was produced by adding the same frames, however, while shifting their positions according to the motion of the comet. The faint, star-like image of Comet Halley is now visible (in circle, at centre); all other objects (stars, galaxies) in the field are "trailed". A satellite trail is visible at the very top. The field measures 60 x 40 arcsec2; North is up and East is left in both photos.

难道哈伯最近没拍吗？？

哈伯的主页上最近只有火星……
VLT那边还没见火星的照片呢……

而且注意了，这批图是3月拍的。

说明如下：Seventeen years after the last passage of Comet Halley, the ESO Very Large Telescope at Paranal (Chile) has captured a unique image of this famous object as it cruises through the outer solar system. It is completely inactive in this cold environment.

No other comet has ever been observed this far - 4200 million km from the Sun - or that faint - nearly 1000 million times fainter than what can be perceived with the unaided eye.

This observation is a byproduct of a dedicated search [1] for small Trans-Neptunian Objects, a population of icy bodies of which more than 600 have been found during the past decade.

第一张是短曝光的么?

好啊，拍它的镜子中有melipal，这是我最关心的了

着还能看清吗？

看是看不清楚了。。。

我什么也看不见

请去眼科医院检查一下。
