Explanation: The disk of our Milky Way Galaxy is home to hot nebulae, cold dust, and billions of stars. The red
nebulae visible in the above contrast-enhanced picture are primarily emission nebulae, glowing clouds of
hydrogen gas heated by nearby, bright, young stars. The blue nebulae are primarily reflection nebulae, clouds of
gas and fine dust reflecting the light of nearby bright stars. Pe

有的。我用的是celestron C90 mak,150刀。比较轻便了,一般摄影三脚架就可以了~
这个望远镜附带的32mm eyepiece (39倍放大)能用,因为这个scope f13,不太挑
eyepiece。可以再买一个8-9mm eyepiece用来看行星(大概~140倍放大),也不用买顶

另外这个望远镜还附带一个finder scope,烂得掉渣。另外45度的diagonal有两个问题

* Great Sky River (1987) -- 1988 Nebula Nominee

导语:刚刚结束的国际超级计算大会(ISC)公布了最新的全球高性能计算机500强,中国
曙光公司研发的星云(Nebulae)系统名列第二,一举超过了众多欧洲和日本的系统。《
纽约时报》撰文称,该事件凸显了中国在科技领域日益增长的实力和雄心。
以下为文章全文:
曙光星云位于深圳的超级计算中心,运算速度达到1.27 PFLOPS,一个PFLOPS相当
于每秒可进行1千万亿次数学运算。
此外,曙光星云的峰值运算速度是世界最快的,不过该指标的重要性不及在标准化

世界最快的电脑仍是美国田纳西州橡树岭国家实验室的Cray Jaguar超级计算机,
该系统主要用于模拟核试验等,去年十一月该电脑在测试中取得了1.75 PFLOPS的运算
分数。
去年中国排行最靠前的是国防科技大学研制的天河一号,名列第五位,不过今年降
至第七。
美国在这一榜单中仍具有统治性的地位,既是生产最多超级计算机的国家,也是安

其实ABC心里也很痛苦,他们父母的“accent and broken sentences”英语“

导语:刚刚结束的国际超级计算大会(ISC)公布了最新的全球高性能计算机500强,中国曙光公司研发的星云(Nebulae)系统名列第二,一举超过了众多欧洲和日本的系统。《纽约时报》撰文称,该事件凸显了中国在科技领域日益增长的实力和雄心。
以下为文章全文:
曙光星云位于深圳的超级计算中心,运算速度达到1.27 PFLOPS,一个PFLOPS相当于每秒可进行1千万亿次数学运算。
此外,曙光星云的峰值运算速度是世界最快的,不过该指标的重要性不及在标准化运算测试中获得的实际运算速度值。
世界最快的电脑仍是美国田纳西州橡树岭国家实验室的Cray Jaguar超级计算机,该系统主要用于模拟核试验等,去年十一月该电脑在测试中取得了1.75 PFLOPS的运算分数。
去年中国排行最靠前的是国防科技大学研制的天河一号,名列第五位,不过今年降至第七。
美国在这一榜单

超越IBM曾经的王者“走鹃”(Roadrunner)
在德国汉堡举行的2010年国际超级计算大会上,TOP500.org组织公布了第35 届全球超
级计算机五百强排行榜,中国新近研发完成的“星云”(Nebulae)高居亚军位置,一举
创造了中国在这项排行榜上的傲人新纪录,同时中国“天河一号”排在第七位。这样,
中国不但打破了美国对前三甲的长期垄断,也第一次在前十名中占据了两个席位。
“星云”超级计算机是前十强中的唯一一名新成员。它位于深圳国家超级计算机中心,
由曙光公司的曙光TC3600刀片系统集群组成,内部采用Intel Xeon X5650 2.66GHz六核
心处理器、NVIDIA Tesla C2050计算卡,总计120640个计算核心,运行Linux操作系统
,最大浮点性能1.271PFlops(全球第三个突破1PFlops大关),峰值可达2.9843PFlops,
甚至超过美洲虎28%之多,是全球理论性能最高的超级计算机。
位于天津国家超级计算中心的中国“天河一号”(Tianhe-1)上

新浪科技讯 北京时间8月2日晚间消息,据国外媒体报道,全球超级计算机500强排
名今年11月将进行更新,而中国的超级计算机“星云”(Nebulae)届时可能问鼎冠军宝
座。
全球超级计算机500强排行榜每年更新两次,分别在每年的5月和11月发布。在今年
5月份的排行榜中,位于中国深圳国家超级计算机中心的“星云”排名第二,而排名首
位的是美国橡树岭国家实验室的“美洲虎”(Jaguar)。
美洲虎”的计算速度为每秒钟1.76千万亿次(PFlops)浮点运算,而“星云”的计算
速度为每秒钟1.27千万亿次(PFlops)浮点运算。但是,“星云”的的理论最高计算速度
为每秒钟2.98千万亿次(PFlops)。
而近期的测试结果也显示,“星云”的实际计算速度也趋于该理论最高速度。因此
,在11月即将推出的新一期全球超级计算机500强排名中,“星云”很可能问鼎冠军宝
座。至于“美洲虎”,有报道称将在未来五年内进行重大升级。否则,“美洲虎”在未
来几年的排名可能要在下半区了(250名之后)。
当然,中国

根据这篇文章,哈勃能够分辨的在月球表面的最小的尺寸是200米(我也见过说60米分

Hubble cannot see the Apollo artifacts on the Moon.
This question is sent to me roughly once a month, and sometimes even more
often: why don't we shut up the people who think the Apollo Moon landings
were faked by pointing Hubble at the Moon and taking pictures of the Apollo
sites?
Well, one reason is that, duh, NASA and astronomers have better things to do

Anonymous has sure been quiet lately, but today's federal bust of Megaupload
riled 'em up good: a retaliatory strike against DoJ.gov has left it
completely dead.
DownForEveryoneOrJustMe.com is reporting the department's site as
universally nuked, and an Anonymous-affiliated Twitter account is boasting
success. This is almost certainly the result of a quickly-assembled DDoS
attack—and easily the widest in scope we've seen in some tim... 阅读全帖
