Information about Sun

-

1. The voice of the sun

The sun is constantly "humming", but it is not possible to hear this sound in space because there is no medium to transmit the sound. NASA created the sound, a deep low-frequency sound, by converting the motions of the plasma on the Sun's surface into data.

2. Pressure of the heart of the Sun

The pressure at the center of the Sun is 340 billion times greater than the pressure of Earth's oceans. This pressure is so high that hydrogen atoms fuse together to form helium, and this process provides us with light and energy.

3. Photon travel

A photon (particle of light) when it is created in the center of the Sun takes about 100,000 years to reach the surface of the Sun. This is because the photon is absorbed and re-emitted many times in the interior of the Sun, making its journey extremely slow.

4. The color of the Sun's surface

Although we see the sun as yellow, the actual color of the sun is white. Earth's atmosphere scatters sunlight, causing it to appear yellow.

5. Sun's magnetic storms

Magnetic storms on the Sun, called "solar flares," are so powerful that if their energy were harnessed on Earth, a single flare could power the entire world for thousands of years.

6. The weight of the sun

The mass of the Sun is about 1.989 × 10³⁰ kg, which is 330,000 times the mass of the Earth. It is so heavy that it accounts for 99.86% of the mass of the entire solar system.

7. The Future of the Sun

The Sun is about 4.6 billion years old and will live for another 5 billion years. But eventually, it will run out of fuel and turn into a "red giant", after which it will become a "white dwarf".

8. Objects moving around the Sun

Not only planets, but also thousands of asteroids, comets and space debris revolve around the Sun. The gravitational binding of all these objects around the Sun gives us an idea of ​​its strength

سورج کی حیرت انگیز اور دلچسپ معلومات 

1. سورج کی آواز

سورج مستقل طور پر "گنگنا" رہا ہے، لیکن اس آواز کو خلا میں سننا ممکن نہیں کیونکہ وہاں کوئی ذریعہ نہیں ہے جو آواز کو منتقل کرے۔ ناسا نے سورج کی سطح پر موجود پلازمہ کی حرکات کو ڈیٹا میں تبدیل کرکے اس کی آواز تخلیق کی ہے، جو کم فریکوئنسی کی ایک گہری آواز ہے۔

2. سورج کے قلب کا پریشر

سورج کے مرکز میں دباؤ 340 بلین گنا زیادہ ہے زمین کے سمندر کے دباؤ سے۔ یہ دباؤ اتنا زیادہ ہے کہ ہائیڈروجن کے ایٹمز آپس میں مل کر ہیلیئم میں تبدیل ہو جاتے ہیں، اور یہ عمل ہمیں روشنی اور توانائی فراہم کرتا ہے۔

3. فوٹون کا سفر

ایک فوٹون (روشنی کا ذرہ) جب سورج کے مرکز میں پیدا ہوتا ہے تو اسے سورج کی سطح تک پہنچنے میں تقریباً 1 لاکھ سال لگتے ہیں۔ یہ اس وجہ سے ہے کہ فوٹون سورج کے اندرونی حصوں میں کئی بار جذب اور دوبارہ خارج ہوتا ہے، جس سے اس کا سفر انتہائی سست ہو جاتا ہے

4. سورج کی سطح کا رنگ

اگرچہ ہم سورج کو زرد دیکھتے ہیں، لیکن حقیقت میں سورج کا اصل رنگ سفید ہے۔ زمین کی فضا سورج کی روشنی کو بکھیرتی ہے، جس کی وجہ سے وہ زرد نظر آتا ہے۔

5. سورج کے مقناطیسی طوفان

سورج پر مقناطیسی طوفان، جنہیں "سولر فلیئرز" کہتے ہیں، اتنے طاقتور ہوتے ہیں کہ اگر ان کی توانائی کو زمین پر استعمال کیا جائے تو ایک فلیئر پوری دنیا کو ہزاروں سال تک بجلی فراہم کرسکتا ہے۔

6. سورج کا وزن

سورج کا وزن تقریباً 1.989 × 10³⁰ کلوگرام ہے، جو زمین کے وزن سے 330,000 گنا زیادہ ہے۔ یہ اتنا بھاری ہے کہ یہ پورے سولر سسٹم کے ماس کا 99.86% حصہ ہے۔

7. سورج کا مستقبل

سورج تقریباً 4.6 بلین سال پرانا ہے اور یہ مزید 5 بلین سال تک زندہ رہے گا۔ لیکن آخر کار، یہ اپنے اندر موجود ایندھن ختم کر دے گا اور ایک "ریڈ جائنٹ" میں تبدیل ہوجائے گا، جس کے بعد یہ ایک "وائٹ ڈوارف" بن جائے گا۔

8. سورج کے گرد حرکت کرنے والی چیزیں

صرف سیارے ہی نہیں، بلکہ ہزاروں سیارچوں ، دمدار ستارے اور خلائی ملبہ بھی سورج کے گرد گھومتا ہے۔ سورج کے گرد ان تمام اشیاء کا کشش ثقل کے ذریعے بندھا ہونا ہمیں اس کی طاقت کا اندازہ دیتا ہے

liquid water discovered on Mars

liquid water discovered on Mars This is the first clear evidence of liquid water, not just frozen ice, discovered on Mars. A groundbreaking discovery published in Science has confirmed that Mars once had liquid water, offering new insights into the planet’s climate and potential for supporting life.  Researchers analyzing data from NASA’s Curiosity rover identified ancient "wave ripples" in rocks at the Gale Crater region, dating back 3.7 billion years. These ripples, formed by wind and water, indicate the presence of a shallow, open-air lake about 2 meters (6.5 feet) deep.  The discovery highlights a time when Mars had a warmer climate and a thicker atmosphere capable of sustaining liquid water — a critical ingredient for life as we know it. This revelation has far-reaching implications for understanding Mars' habitability and planning future missions.  The presence of liquid water raises the possibility that microbial life once thrived on the planet. Additionally, remna...

A black diamond

A black diamond that is actually an apple? Of course, you have seen apples of various colors including green and red, but there is one region in the world where black apples grow. By the way, the color of this apple is deep violet, but it looks black, which is why it is called in English  (black diamond apple)  is called and it is found only in Tibet. The black diamond apple stands out from other apples due to its luxurious appeal and rarity and also arouses people's curiosity. The distinctive color of the black diamond apple is actually attributed to the unique geographical location of Ningchi, a small town nestled among the mountains in the Tibet Autonomous Region of China. Apples found at high altitudes are exposed to intense ultraviolet light during the day, causing significant temperature fluctuations. Such climatic conditions contribute to the production of the characteristic black color of the apple. Although the inside of the black diamond apple is like a regular apple...

Strong and secure shelters Switzerland is the only country in the world that can evacuate all its citizens (114%) to underground safe rooms, whenever an emergency occurs. There are more than 300,000 strong and secure shelters, all of which can shelter a total of 8.6 million people, compared to the country's current population of 8.3 million. Switzerland's security system is highly organized and prepared for all types of emergency situations, making it unique worldwide. The special feature of this system is that it is capable of sheltering not only every citizen but also additional persons, and its structure is based on the following features: 1. Number and capacity of underground shelters There are more than 300,000 shelters in Switzerland, most of which are underground and made of reinforced concrete. These shelters can provide protection to a total of 8.6 million people, compared to the country's current population of about 8.3 million. This means that space is reserved f...
