سحابی‌ها واقعاً شگفت انگیز هستند، لغت سحابی از کلمه لاتین ابر گرفته شده است و به ابرهای عظیم گرد و غبار، هیدروژن، گاز هلیوم و پلاسما اشاره دارد. به سحابی اغلب مهد کودک‌های ستاره‌ای، یعنی محل تولد ستاره‌ها نیز گفته می‌شود و برای قرن‌ها، کهکشان‌های دور اغلب با این ابرهای عظیم اشتباه گرفته می‌شدند

The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. On Telegram’s website, it says that Pavel Durov “supports Telegram financially and ideologically while Nikolai (Duvov)’s input is technological.” Currently, the Telegram team is based in Dubai, having moved around from Berlin, London and Singapore after departing Russia. Meanwhile, the company which owns Telegram is registered in the British Virgin Islands. Some privacy experts say Telegram is not secure enough But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website.
