High mountains in the sea

  Marine experts have discovered a 3 thousand 109 meter high mountain in the sea

 According to a report by the American newspaper New York Post, researchers from the Schmidt Ocean Institute in California have discovered a huge mountain 3,109 meters high in the Pacific Ocean, about 1,448 kilometers from the coast of Chile.

This sea-water mountain is higher than Mount Olympus in Greece which is 2,917 meters high.

The mountain is part of an underwater mountain range teeming with life, home to ancient corals and rare marine species.

The mountain was discovered by researchers during a 28-day expedition led by the Schmidt Ocean Institute on the undersea research vessel RV Falkor (To).

The team of researchers used an underwater sonar system to map the mountain in detail.

Jyothika Virmani, executive director of the Schmidt Ocean Institute, said the sonar system uses sound waves to travel downward and return through the surface, measuring the time it takes for the sound to return from the surface. By doing this we can create a detailed map of the sea floor. 

This discovery is significant because only 26 percent of the ocean floor has been mapped at this level, even though the ocean floor covers 71 percent of the Earth's surface.

Marine experts estimate that there are at least 100,000 seamounts over 1,000 meters high around the world, which are home to a large number of aquatic life.

سمندر میں بلند پہاڑ

  سمندری ماہرین نے سمندر کے اندر 3 ہزار 109 میٹر بلند پہاڑ دریافت کر لیا

 امریکی اخبار نیو یارک پوسٹ کی ایک رپورٹ کے مطابق کیلیفورنیا میں واقع شمٹ اوشین انسٹی ٹیوٹ کے محققین نے چلی کے ساحل سے تقریباً 1 ہزار 448 کلومیٹر دور بحر الکاہل میں 3 ہزار 109 میٹر بلند بہت بڑا پہاڑ دریافت کیا ہے۔

سمندر کے پانی میں موجود یہ پہاڑ یونان میں موجود ماؤنٹ اولمپس سے بھی اونچا ہے جو 2 ہزار 917 میٹر بلند ہے۔

یہ پہاڑ سمندر کے پانی کے اندر موجود ایک پہاڑی سلسلے کا حصّہ ہے جو زندگی سے بھرا ہوا ہے، اس پر قدیم مرجان اور نایاب سمندری انواع آباد ہیں۔

اس پہاڑ کو محققین نے ایک 28 روزہ مہم کے دوران دریافت کیا جس کی قیادت شمٹ اوشین انسٹی ٹیوٹ نے سمندر کے اندر تحقیق کے لیے مختص سمندری جہاز آر وی فالکور (ٹو) پر کی۔

محققین کی ٹیم نے پہاڑ کا تفصیلی نقشہ بنانے کے لیے جہاز کے نیچے سونر سسٹم کا استعمال کیا۔

شمٹ اوشین انسٹی ٹیوٹ کی ایگزیکٹیو ڈائریکٹر جیوتیکا ویرمانی نے بتایا ہے کہ سونر سسٹم کی مدد سے آواز کی لہریں نیچے کی طرف سفر کرتی ہیں اور سطح سے ہو کر واپس آتی ہیں یوں سطح سے آواز کو واپس آنے میں جو وقت لگتا ہے اس کی پیمائش کر کے ہم سمندری فرش کا تفصیلی نقشہ بنا سکتے ہیں۔ 

یہ دریافت اس لیے اہم ہے کیونکہ اس سطح پر صرف 26 فیصد سمندری فرش کا نقشہ بنایا گیا ہے حالانکہ سمندری فرش زمین کی سطح کے 71 فیصد حصّے پر محیط ہے۔

سمندری ماہرین کا اندازہ ہے کہ دنیا بھر میں کم از کم 1 لاکھ سمندری پہاڑ 1 ہزار میٹر سے اونچے ہیں جو آبی حیات کی بہت بڑی تعداد کا مسکن ہیں۔

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...
