ஜேம்ஸ் வெப் தொலைநோக்கி அமெரிக்காவின் நாசா, ஐரோப்பாவின் ஈசா, கனடா விண்வெளி ஆராய்ச்சி மையங்கள் இணைத்து அனுப்பிய தொலைநோக்கி ஆகும். ஏற்கனவே விண்ணில் இருக்கும் hubble தொலைநோக்கியின் அப்டேட் தான் இந்த ஜேம்ஸ் வெப் தொலைநோக்கி.

பூமியில் இருந்து அதிகபட்சம் 1,500,000 km தூரத்தில் இது நிலைநிறுத்தப்பட்டுள்ளது. பூமியில் இருந்து இது இருக்கும் குறைந்தபட்ச தொலைவே 374,000 km தூரம் ஆகும்.

ஜேம்ஸ் வெப் எடுத்த புகைப்படத்தை இன்றுதான் (11/07/2022) நாசா வெளியிட்டது.

ஜேம்ஸ் வெப் எடுத்த புகைப்படத்தை பற்றி பார்க்கலாம். குட்டி குட்டி நட்சத்திரங்கள், மினிமைஸ் செய்யப்பட்ட பிரபஞ்ச கூட்டங்கள், நட்சத்திர கூட்டங்கள் என்று எல்லாம் அடங்கிய புகைப்படம்தான் அது. ஒரு பிடி மண்ணை கையில் வைத்து உங்கள் தோள் பட்டையில் கேமரா வைத்து கையில் உள்ள மண்ணை போட்டோ எடுத்தால் எப்படி இருக்கும். அப்படித்தான் விண்வெளியில் ஒரு பிடி மண் அளவிற்கு உள்ள குறிப்பிட்ட பகுதியை மட்டும் படம் பிடித்து ஜேம்ஸ் வெப் அனுப்பி உள்ளதாக நாசா வர்ணித்து உள்ளது.

The keto diet emphasizes weight loss through fat-burning. The goal is to quickly lose weight and ultimately feel fuller with fewer cravings, while boosting your mood, mental focus and energy. According to keto proponents, by slashing the carbs you consume and instead filling up on fats, you safely enter a state of ketosis. That’s when the body breaks down both dietary and stored body fat into substances called ketones. Your fat-burning system now relies mainly on fat – instead of sugar – for energy. While similar in some ways to familiar low-carb diets, the keto diet’s extreme carb restrictions – about 20 net carbs a day or less, depending on the version – and the deliberate shift into ketosis are what set this increasingly popular diet apart. In fact, other eating plans are pulling in keto elements, so you can find versions like eco-keto and at least one commercial diet that incorporates keto-friendly products.
