Европейское космическое агентство (ESA) поделилось новыми снимками нашей главной звезды, которые сделали ещё в марте 2023 года. Сделаны они были зондом Solar Orbiter на расстоянии менее чем в 74 млн км от Солнца.
Фотографии в самом высоком доступном разрешении, в котором можно рассмотреть видимую поверхность звезды. На снимках хорошо видны солнечные пятна, из-за того, что температура в них ниже, они излучают меньше света.
На первом фото — Солнце в видимом диапазоне, на втором — магнитограмма, на третьем — движение вещества на поверхности Солнца, на четвёртом — Солнце в ультрафиолете.

At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders.
