বিষুণ খারের নামে নামকরণ হল প্লুটোর ক্রেটারের! চেনেন কি এই ভারতীয় বিজ্ঞানীকে

সম্প্রতি ইন্টারন্যাশনাল অ্যাস্ট্রোনমিকাল ইউনিয়ন প্লুটো গ্রহের একটি ক্রেটার বা গর্তের নাম রেখেছে বিষুন কারের নামে। অথচ এই ভারতীয় পদার্থ বিজ্ঞানীকে দেশের মানুষই ভাল করে চেনেন না। ১৯৩৩ সালে বারানসীতে জন্মেছিলেন বিষুণ খারে। দীর্ঘদিন তিনি কিংবদন্তি মার্কিন পদার্থবিদ কার্ল সেগানের সহকারী হিসেবে কাজ করেছিলেন। তবে পদার্থবিদ্যার জগতে তাঁর নাম উজ্জ্বল হয়ে আছে প্লুটো নিয়ে তাঁর গবেষণাধর্মী কাজের জন্য। এই বিজ্ঞানী সম্পর্কে আরও তথ্য রইল এই ভিডিওয়।
