  Scientist  in Ancient India     In Ancient Time India had been vishwa guru . There were so many rishis,  munis  born in  the land of India.   they are always  in the search of knowledge  like a today's Scientist , so we can call it as Ancient Indian Scientist . There are so many Ancient Scientist and today we are talking about -:     Science and Mathematics were highly developed during the ancient period in India.  Ancient Indians contributed immensely to the knowledge in Mathematics as well as various branches of Science.   In this section, we will read about the developments in Mathematics and the scholars who contributed to it. You will be surprised to know that many theories of modern day mathematics were actually known to ancient Indians.  However, since ancient Indian mathematicians were not as good in documentation and dissemination as their counterparts in the modern western world, their contributions did not find the place they deserved. Moreover, the western world

    NASA Captured The 'Sound' From A Black Hole, And It's Super Eerie NASA has released a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away.   The black hole is at the center of the Perseus cluster of galaxies, and the acoustic waves coming from it have been transposed up 57 and 58 octaves so they're audible to human hearing. The result (below), released by NASA in May, is a sort of unearthly (obviously) howling that, if we're honest, sounds not only spooky, but a little bit angry.  It's the first time these sound waves have been extracted and made audible. So what's going on here? We might not be able to hear sound in space, but that doesn't mean there isn't any. In 2003, astronomers detected something truly astonishing: acoustic waves propagating through the copious amounts of gas surrounding the supermassive black hole at the centre of the Perseus galaxy cluster, which is now renowne

what will happen when our sun dies ? If you worry about when the sun will die, never fear: that moment is billions of years away. The sun gives energy to life on Earth, and without this star, we wouldn't be here. But even stars have limited lifetimes, and someday our sun will die. You don't need to worry about this solar death anytime soon, though. Like all stars, a churning fusion engine fuels the sun, and it still has a lot of fuel left — about 5 billion years' worth.    Stars like our sun form when a huge cloud of gas (mostly hydrogen and helium) grows so large that it collapses under its own weight. The pressure is so high in the center of that collapsing mass of gas that the heat reaches unimaginable levels, with temperatures so hot that hydrogen atoms lose their electrons. Those naked hydrogen atoms then fuse together into helium atoms, and that reaction releases enough energy to counter the intense pressure of gravity collapsing the cloud of gas. The b

 The closest star to Earth is a triple-star system called Alpha Centauri.   The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are about 4.35 light-years from Earth, according to NASA (opens in new tab). The third star is called Proxima Centauri or Alpha Centauri C, and it is about 4.25 light-years from Earth, making it the closest star other than the sun. According to NASA, Alpha Centauri A and B are on average about 23 astronomical units (AU) from each other — a little more than the distance between the sun and Uranus. (An astronomical unit is the average distance between Earth and the sun, which equals 92,955,807 miles or 149,597,870 kilometers.) The closest the two stars ever come to each other is 11 astronomical units, according to NASA (opens in new tab)   To the naked eye, the Alpha Centauri A and B shine as one, making them the third brightest "star" in our night sky. The two separate stars can be seen through a small tel

  The Crab Nebula   The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 A.D., is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.   The nebula was discovered by English astronomer John Bevis in 1731, and it corresponds with a bright supernova recorded by Chinese astronomers in 1054. The nebula was the first astronomical object identified that corresponds with a historical supernova explosion  

 First  Image of Universe  Deepest Infrared   by NASA’s James Webb    | James webb space telescope first image    Every Single Dot of this Image is Galaxy from Newest to Oldest   Washington: The clearest image to date of the early universe, going back 13 billion years, has been released - and it doesn't disappoint. The stunning shot, released in a White House briefing by President Joe Biden, is overflowing with thousands of galaxies and features some of the faintest objects observed, colorized in blue, orange and white tones. The image, captured by the James Webb Space Telescope, the most powerful to be placed in orbit, covers a patch of the sky "roughly the size of a grain of sand held at arm's length by someone standing on earth", NASA administrator Bill Nelson said.  NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 072
