Ring Nebula Location

 This is the Ring Nebula or M57




Original image



- When it was first seen through a telescope in the 1700s, it looked round and fuzzy, and astronomers at the time thought it looked like a distant planet. It was named by William Herschel. [Mobile]


- The Ring Nebula is the remnant of a dying Sun-like star. The star has shed its outer layers of gas into space at the end of its life, and its inner core is slowly becoming a white dwarf star.

- You can see it in the picture as a hollow ring. But scientists have now seen with advanced instruments like the James Webb Telescope that its true shape is not a hollow ring, but rather an elongated structure like a rugby ball. We see it as a ring because it is tilted towards our Earth in such a way that we are looking along its center.


- It is located about 2,300 light-years from Earth.  It would take millions of years to get there with our current technology!


- The nebula is about 1 light-year in diameter, which means that it takes a full year for light to travel from one end to the other.






- The nebula's gases are expanding outward at about 40,000 kilometers per hour. This may seem like a very fast speed, but compared to the vastness of space, this speed is very slow.


- The brightest parts of the nebula are red, green, and blue. These colors come from the atoms of different gases:

* Red - nitrogen and hydrogen.

* Green - oxygen.

* Blue - helium.


- The white dwarf at the center of the nebula is about 60% the size of our Sun and is incredibly hot. Its surface temperature is about 120,000 degrees Celsius.


- This central white dwarf is now exhausting all its energy and cooling and fading away. In a few billion years, it will become a black dwarf and merge into the darkness of the universe.






 - It is located in the constellation Lyra in the night sky and is so bright that it can be easily seen using a small telescope or powerful binoculars. It is the 57th object in the Messier catalog, hence its other name M57.


- The James Webb Space Telescope has found about 20,000 small ball-like structures within this nebula, which are thought to be made of hydrogen gas. This discovery has given scientists new ideas about the formation and evolution of the nebula.

The world's first selfie

The world's first selfie was taken 185 years ago Where did this selfie actually come from?Which was the world's first selfie? Who took that selfie? About 185 years ago. At that time there was  no smartphone, there was no distinction  between front camera and primary camera. The world's first selfie was taken in 1839 with that camera, which means camera.  The photograph was taken by Robert Cornelius, a Philadelphia chemist. Although a chemist by profession, his true chemistry was with photography. While doing various experiments with taking pictures, it suddenly came to my mind to take pictures myself.  Place the camera at the back of the home shop. Remove the lens cover and capture the image immediately into the frame. Pose for 1 minute. Then cover the lens again. The world's first selfie was created.  Under the picture Robert Cornelius wrote 'The first light picture ever taken. 1839'. Cornelius took another selfie four years after this photo.  30-year-old ...

discovery inside the pyramid image

  পিরামিডের ভিতরে নতুন আবিষ্কার! বিজ্ঞানীরা কী খুঁজে পেলেন | New discovery inside the pyramid! What did scientists find গিজার মহাপিরামিডকে (Great Pyramid of Giza) ঘিরে কৌতূহল এবং রহস্যের শেষ নেই। প্রায় ৪,৫০০ বছর আগে নির্মিত এই স্থাপত্য আজও মানবসভ্যতার এক অমীমাংসিত ধাঁধাঁ। কীভাবে প্রাচীন মিশরীয়রা এত বড় বড় পাথরের ব্লক কেটে, টেনে, সঠিকভাবে সাজিয়ে এমন নিখুঁত স্থাপত্য গড়ে তুলেছিল – তা আজও বিজ্ঞানীদের কাছে বিস্ময়ের বিষয়। তবে সম্প্রতি নতুন এক গবেষণা আবারো সারা বিশ্বে আলোচনার ঝড় তুলেছে, কারণ বিজ্ঞানীরা পিরামিডের ভেতর এমন এক জায়গা খুঁজে পেয়েছেন, যা আগে কেউ জানতো না। গোপন চেম্বারের সন্ধান ২০১৭ সালে “স্ক্যানপিরামিডস প্রকল্প” (ScanPyramids Project)-এর আওতায় আন্তর্জাতিক গবেষক দল এক অভিনব প্রযুক্তি ব্যবহার করে গিজার পিরামিড স্ক্যান করেন। এতে দেখা যায়, পিরামিডের ভেতরে আগে অজানা এক বিশাল ফাঁপা জায়গা বা চেম্বার রয়েছে। ধারণা করা হয়, এর দৈর্ঘ্য প্রায় ৩০ মিটার, যা একটি যাত্রীবাহী বিমানের আকারের সমান। এই রহস্যময় চেম্বারটিকে বিজ্ঞানীরা নাম দিয়েছেন “বিগ ভয়েড” (Big Void)। কী থাকতে পারে ভেতরে? এখন পর্যন্ত...

Voyager 1 Image How big is the universe

  Voyager 1  How big is the universe? ||  Voyager 1 How big is the universe? Voyager 1 Human curiosity has always been boundless. Looking at the stars in the sky, we have wondered since ancient times - what is there beyond? Is life possible outside of Earth? The story of space exploration began with this curiosity. And the longest-lasting hero of that expedition is the Voyager 1 spacecraft, which is still running on the path of the unknown. Voyager 1's journey NASA launched the Voyager 1 spacecraft in 1977. It was originally designed to closely observe the outer planets of the solar system—Jupiter and Saturn. But even after the mission ended, Voyager 1 did not stop. It has now reached a distance of about 26 billion kilometers from Earth, traveling at a speed of about 60,000 kilometers per hour. Earth and Moon  While that number may seem huge, it's actually quite small in the context of the universe. For comparison, a light-year is about 9.46 trillion kilometers. Tha...
