【未看金星凌日&天文愛好研友的福音】

6月6日，NASA（美國國家航空航天局）對金星凌日做了全程的報道，也給了十五分鐘更新一次的4096*4096分辨率的超高清大圖（每個圖3M多，其清晰度真是無以倫比，可以看見太陽黑子等），但NASA并未對之前發出的大圖提供繼續預覽和保存的服務。

幸運的是，東風本人今天上午特地抽空每隔15分鐘搜集一次超清大圖，可以說投入了很多時間和精力，終于對后半部分做了很好的歸類和收集。

更偶然和幸運的是，今天無意中進入了NASA的天文圖片檔案館，找到了1995年6月16日更新至今天的高清天文事件圖片全記錄，可以毫不夸張的說，NASA的很多超清圖片的質量程度之高是令人贊嘆的。

Explanation: Today Venus moves in front of the Sun. One way to follow this rare event is to actively reload the above live image of the Sun during the right time interval and look for an unusual circular dark dot. The smaller sprawling dark areas are sunspots. The circular dot is the planet Venus. The dark dot will only appear during a few very specific hours, from about 22:10 on 2012 June 5 through 4:50 2012 June 6, Universal Time. This transit is the rarest type of solar eclipse known -- much more rare than an eclipse of the Sun by the Moon or even by the planet Mercury. In fact, the next transit of Venus across the Sun will be in 2117. Anyone with a clear view of the Sun can go outside and carefully view the transit for themselves by projecting sunlight through a hole in a card onto a wall. Because this Venus transit is so unusual and visible from so much of the Earth, it is expected to be one of the more photographed celestial events in history. The above live image on the Sun is being taken by the Earth-orbiting Solar Dynamics Observatory and can be updated about every 15 minutes.
