📡 تلسکوپ فضایی #جیمزوب، جَو (اتمسفر) سیاره‌هایِ فراخورشیدی را با تجهیزاتِ پیشرفته در نور فروسرخ بررسی و تصویربرداری خواهد کرد. سیاره‌های #فراخورشیدی، سیاره‌هایی‌اند که به دور ستاره‌ای غیر از خورشیدِ ما چرخش می‌کنند. اولین بار در دههٔ ۱۹۹۰ میلادی (۱۳۷۰) کشف شدند. تا کنون، بیش از ۴۰۰۰ سیاره در ابعاد و فواصل مختلف شناسایی شده است.

این سیاره‌ها در درون کهکشان راه‌شیری قرار دارند. سیاره‌هایی که در خارج از کهکشان راه‌شیری قرار دارند به سیاره‌های فراخورشیدیِ فراکهکشانی معروف‌اند؛ به‌ دلیل فواصل زیاد [🔗]، کشفِ آن‌ها بسیار دشوار است.

تکنیک‌های زیادی برای شناسایی این سیارات وجود دارد. تکنیک رایجی که رصدخانهٔ وِب نیز استفاده خواهد کرد، Coronagraph نام دارد: نورِ ورودی ستاره به تلسکوپ مسدود می‌شود تا سیاره‌هایِ اطرافِ آن نمایان شود.

کاندیدهای اولیه برای کاوش‌ سیستم‌های فراخورشیدی با نام‌های: 51 Eridani (فاصله از زمین: ۹۶ سال-نوری🔗) و HR 8799 (فاصله از زمین: ۱۳۳ سال-نوری). —🌐— [پست قبل: 🔗]، #رصد_کیهان

Telegram Desktop App Not Working on Windows?

Run Telegram in Compatibility Mode

The fix won't work if the app was functioning normally a few days ago and you haven't made drastic changes to the OS or updated Windows. If the issue appears after a Windows update, or you're running an older version of Telegram, it's possible the current version of the app isn't compatible with your operating system. Therefore, update your app to the most recent and compatible version or roll back your Windows update.If you can't do either, run the app in compatibility mode. You might not have used it before, but it is one of the handy hidden modes in Windows.However, before doing that, run the compatibility troubleshooter that may resolve the issue right away. To run the troubleshooter, right-click on Telegram's shortcut and go to Properties. Navigate to the Compatibility tab in the Telegram Properties window and click Run compatibility troubleshooter.If the troubleshooter doesn't identify the issue, manually adjust compatibility settings. To do so, follow these steps: Check the box for Run this problem in compatibility mode for: and select Windows 8 from the dropdown menu. Hit OK after clicking Apply.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
