🌌 سرنخی از ماده تاریک 🌌

تصویر پرتو ایکس تلسکوپ ROSAT از یک خوشه کوچک کهکشانی به نام گروه NGC 2300.
این تصویر نشان می‌دهد که گروه کهکشانی NGC 2300 در یک ابر عظیم از گاز داغ (به رنگ بنفش) با قطر ۱.۳ میلیون سال نوری غوطه ور است.

سرنخ موجود برای حضور ماده تاریک این است که ابر داغ باید مدت‌ها پیش در فضا پراکنده می‌شد مگر اینکه توسط گرانش یک جرم عظیم در کنار هم نگه داشته شده باشد.

-فاصله: ۱۵۰ میلیون سال نوری
-واقع در صورت فلکی قیفاووس

Telegram | DID YOU KNOW?

Date: 2025-02-03|

You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. Russian President Vladimir Putin launched Russia's invasion of Ukraine in the early-morning hours of February 24, targeting several key cities with military strikes. The War on Fakes channel has repeatedly attempted to push conspiracies that footage from Ukraine is somehow being falsified. One post on the channel from February 24 claimed without evidence that a widely viewed photo of a Ukrainian woman injured in an airstrike in the city of Chuhuiv was doctored and that the woman was seen in a different photo days later without injuries. The post, which has over 600,000 views, also baselessly claimed that the woman's blood was actually makeup or grape juice. Additionally, investors are often instructed to deposit monies into personal bank accounts of individuals who claim to represent a legitimate entity, and/or into an unrelated corporate account. To lend credence and to lure unsuspecting victims, perpetrators usually claim that their entity and/or the investment schemes are approved by financial authorities. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations.
