Virgin Galactic is one of the universe’s most exciting, futuristic
companies. Bitcoin, the virtual currency, has really captured the
imagination recently as one of the world’s most innovative businesses
looking to the future. So we think it is about time Virgin Galactic
customers can choose to pay with bitcoins.

Astronomers have found the remnants of a thousand dead and dying stars in the

The findings, from a new sky survey, roughly doubles the known number of so-

别激动:
从《质量效应3》的多人部分被首次披露以来,玩家们就一直在猜测多人游戏究竟会如
何影响单人部分的战役,尤其是结局部分。  现在Bioware的Jarett Lee透露了玩家
们如何达成《ME3》的完美结局,并且表示“你不必进行多人游戏来获得单人游戏的完
美结局。”
Lee表示所有的困惑源自于如果玩家不进入多人游戏或者完成IOS上的《质量效应:
渗透者》,Galactic Readiness就会一直保持在50%。
但实际上,Galactic Readiness并不是完美结局达成的关键因素,而是“
Effective Military Strength”条。“关注那条计量表,”Lee说到。“那才是显示你
的结局有多完美的指标。”
EMS可以通过在单人战役中收集“War Assets(战争财产)”获得,而且“战役中会
有很多这样的物品。”Lee说到。
Galactic Readiness则是EMS的辅助系统,也就是说如果你加入了多人游戏并完成
了《渗透者》,那么你达成“完美结局”所需要的战争财产数量就会相应地减少。

11 月 15 日,总部位于丹佛的 Boom Technologyy公司 ,在丹佛的百年机场,首次展
示了它的超音速载人飞机原型“Baby Boom”,外观十分酷炫,大小约为拟建的超音速
喷气式飞机(“Boom”飞机)的三分之一,使用了通用电气生产的发动机,霍尼韦尔生

实际生产型的Boom会有45个座位。
为了节约重量,座位只有标准国内航班的头等舱水平,不能放倒平躺。
座位的布置是两列单排座位,这样每个乘客既能一览舷窗的景致,又能尽享走廊的便利。
为了缩短飞行时间,Boom的巡航高度约在18288米。在这个高度上,乘客能够看到弧形

最值得一提的是,根据设计,飞行速度 2.2 马赫(为音速的 2.2 倍),是其它飞机所

据美国“国家地理网站”报导,科学家最近第一次在我们的银河系中心发现“吸血鬼”恒星,它们从邻近恒星吸取能量。
台湾今日新闻网报道,科学家曾在银河的其他部分发现这种名叫“蓝色离散星”(blue stragglers)的“吸血鬼”恒星,它们的年龄显然生长得比其他恒星缓慢。它们明显更热、更年轻和更蓝。天文学家认为,这种“蓝色离散星”之所以会如此年轻,是因为它们窃取了其他恒星的氢燃料,或许是透通过碰撞,吞噬了附近的恒星。
这种行为有如“吸血鬼”的恒星经常出现在密集的恒星簇群里,这里的恒星从其他恒星获取能量的机会更多。现在科学家已经在银河系中心被气体笼罩、恒星密集的银河核球(Galactic bulge,银河系盘面中央的隆起区域)里也发现“蓝色离散星”!
美国印地安那大学伯明顿分校和加州大学洛杉矶分校的天文学家威尔?克拉克森说:“长期以来,科学家一直猜测银河核球存在着蓝色离散星,但是没人知道那里有多少这种恒星。最终,我们的研究将会找到这个问题的答案。... 阅读全帖

由英国亿万富翁布兰森(Richard Branson)开办的太空旅游明年某些时候将首航,据布兰森称,当他征询加拿大出生的、科幻电视剧「星际迷航」(Star Trek)宇宙飞船船长扮演者薛特纳(William Shatner)是否愿意报名参加时,遭到薛特纳拒绝。
名称「维京银河之旅」(Virgin Galactic)的太空之旅现在已收到40个国家440人的报名。
布兰森对加通社说:「薛特纳说他害怕前往太空。」80岁的薛特纳承认确实害怕,他接到布兰森电话时开玩笑地问:「如果是免费的,就可以考虑,否则花了钱,有谁能担保安全回来?」
布兰森表示自己在经营航空生意,不会向任何人提供免费太空游。
「维京银河之旅」是次轨道(sub-orbital)之旅,由母宇宙飞船将载有包括两名驾驶在内的八人火箭飞机射入距离地球约110公里的高空,火箭飞机中的人会经历短暂的失重。

一名加拿大少年有可能成为最年少的太空游客。
预计明年首航的「维京银河之旅」(Virgin Galactic)现在已经有440人预订了座位,加拿大卡加利(Calgary)的一名17岁少年是其中一人。
卡加利17岁少年有可能成为最年少的太空游客。图为在美国加州莫贾夫停留的「维京银河之旅」飞船。
由英国亿万富翁布兰森(Sir Richard Branson)创办的「维京银河之旅」现在正进行最后阶段的太空船旅行测试。报名参加此次太空之旅的卡加利17岁少年不愿意透露自己的身分。
旅行商鲍德斯特(Michael Broadhurst)说,很多少年年满16岁时正急于考驾照,而卡加利17岁少年则放眼太空,「他16岁时就为太空旅游存钱,现在17岁,他将在18岁时飞上天。他现在是(太空旅游)名单上唯一的年龄未满18岁的人。
「维京银河之旅」不接纳未满18岁的游客。鲍德斯特说,该少年至少要在一年或两年之后,在父母陪同下乘太空船旅行,眼下他的家人不愿接受任何媒体采访。
据「今日太空」(Space Today)网站称,俄国航空员迪多夫(Gherman Titov)曾是飞往地球轨道最年少的人。他1961年8月乘坐... 阅读全帖

猎户座参宿七人Rigel,参与中国人种的形成。猎户座,天狼星,天龙星都给了黄色人

美国一直宣称要着手登陆火星,甚至火星宇航服都在设计中了,时间大概在2030年
之后。此时,中国的国力和科技实力若是允许,可能也会考虑载人登陆火星,和美

数据说明: 对于尚未发生之事,我们无法用确切数据来比较各国在航天计划上的异
