龙蛋的双极瓣辐射云

说明: 为何单颗恒星能形成这团美丽的星云呢?发射星云NGC6164的中心有颗质量异常庞大的恒星。这颗被喻为牡蛎珍珠的中心恒星,据传是受到神话中的天坛战龙 保护的龙蛋。位于此主题影像中心、编录号为HD148937的这颗恒星,是如此的炽热,因此会辐射紫外光加热周围的气体。这些气体很可能是这颗恒星先前抛出的,具体成因则可能是与另一颗绕行的伴星之间的重力作用所致。而所抛出的物质,可能受到这颗大质量恒星的磁场之引导,最后聚成形状对称的双极瓣星云。跨幅约4光年的NGC6164,座落在南天矩尺座方向约3,600光年远之处。

Telegram Be The Next Best SPAC

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.

That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
