這彗星真的很怪 ..該不會再旋轉

一面很硬  完全不會噴發 所以很暗 .另一面 比較正常
看來應該 是沒希望了 ..下次還是別說世紀大彗星 , 喊越大聲越會漏氣 ..

Comet ISON Goes Green

http://beforeitsnews.com/space/2013/09/comet-ison-goes-green-2466618.html
As NASA and the European Space Agency prepare  their remote photojournalists – Mars Express, Mars Reconnaissance Orbiter and the Curiosity and Opportunity rovers – to capture photos of Comet ISON’s flyby of Mars early next week, amateur astronomers continue to monitor and photograph the comet from backyard observatories across the blue Earth. Several recent color photos show ISON’s bright head or nucleus at the center of  a puffy, green coma. Green’s a good omen – a sign the comet’s getting more active as it enters the realm of the inner solar system and sun’s embrace

=>  變綠色  表示彗星要更活躍了嗎 ??

來亂一下
火星沒有光害,沒有大氣層，一定超讚的,而且自轉一圈跟地球差不多時間，不長時間曝光的話拿一台地球的赤道儀應該可用，引力又小,小赤道儀也可以載大砲,
不過對極軸就要用飄移法了.

火星沒大氣層?他還有風暴勒

[cuteip]

大氣中還充滿很多塵埃

不過再怎樣都比地球好啦!!

現在就算能飛過去應該也來不及了吧!!

在28/9拍攝 (Rolando Ligustri 於美國新墨西哥州)，可見彗星、火星(1.6等) 和小行星433 (Eros，13等)於同一照片上，估計彗星亮度為10等，彗尾長度為10' 左右

有人說 13等
 有人說  10等 ..
