Supermassive black holes are terrifying cosmic entities that hold together entire galaxies with their gravitational power, sucking in and shredding anything that gets too close.

The new active supermassive black hole is at the centre of a galaxy CEERS 1019, which existed around 570 million years after the big bang, according to the University of Texas at Austin. Apart from the supermassive one, researchers also discovered two black holes that are “on the small side” and existed 1 billion and 1.1 billion years after the big bang.

CEERS 1019 is extremely old but that is not the most remarkable thing about it. It is quite lightweight, speaking in galactic terms. It weighs in at aroun 9 million solar masses, which is a lot less than other black holes that also existed in the early universe and were detected by telescopes.

the CEERS 1019 black hole is more like the one at the centre of the Milky Way, which is about 4.6 million times the mass of the Sun.

Despite its relatively diminutive size, the black hole existed so long ago that scientists are struggling to explain how it formed so soon after the universe began. The galaxy hosting the black hole seems to be inhaling as much gas as it can while also cranking out new stars.

WHAT IS JAMES WEB TELESCOPE

ITs INVENTION IS ALMOST AS SIGNIFICANT AS INVENTION OF TELESCOPE BY GALELIO

The James Webb Space Telescope is the largest, most powerful space telescope ever built. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang. The telescope will be able to capture images of some of the first galaxies ever formed. It will also be able to observe objects in our solar system from Mars outward, look inside dust clouds to see where new stars and planets are forming and examine the atmospheres of planets orbiting other stars.

It is a premier observatory with a large infrared telescope that has an approximately 6.5-meter primary mirror.




SOME FINDINGS

  • SMACS 0723: Webb has delivered the deepest and sharpest infrared image of the distant universe so far .This deep field uses a lensing galaxy cluster to find some of the most distant galax ies ever detected.

  • WASP-96b (spectrum): Webb’s detailed observation of this hot, puffy planet outside our solar system reveals the clear signature of water, along with evidence of haze and clouds that previous studies of this planet did not detect.

  • Southern Ring Nebula: This planetary nebula, an expanding cloud of gas that surrounds a dying star, is approximately 2,000 light-years away. Here, Webb’s powerful infrared eyes bring a second dying star into full view for the first time. From birth to death as a planetary nebula, Webb can explore the expelling shells of dust and gas of aging stars that may one day become a new star or planet.

  • Stephan’s Quintet: Webb’s view of this compact group of galaxies, located in the constellation Pegasus, pierced through the shroud of dust surrounding the center of one galaxy to reveal the velocity and composition of the gas near its supermassive black hole. .

  • Carina Nebula: Webb’s look at the “Cosmic Cliffs” in the Carina Nebula unveils the earliest, rapid phases of star formation that were previously hidden.

MAHATMA GANDHI INSPIRES FROM AMERICAN INDEPENDENCE STRUGGLE - ONE LEARNS FROM HISTORY

Image
 On July 4, America celebrates their hard won victory from the oppressive tax system of the British Empire. On this day, about two and a half centuries back, the 13 states of North America, which was part of the British Empire had declared themselves independent and formed the United States of America. The American struggl e for independence was definitely very different from nationalist uprisings in other colonies of the British in the East . In America it was the British settlers who entered into a bitter scuffle with British government authorities. In his call to Indians to resist British domination, Mahatma Gandhi often referred to and drew inspiration from the American revolution. On January 4th, 1932, when Gandhi was actively propagating ‘Satyagraha’, he wrote the following message in his weekly journal, ‘Young India ’ “Even as America won its independence through suffering, valour and sacrifice, so shall India, in God’s good time achieve her freedom by suffering, sacri...

NASA - X-59

NASA’s experimental ‘silent’ supersonic jet X-59 moves into flight line The space agency on Wednesday released a sequence of images showing its experimental X-59 aircraft sitting on the flight line at the Lockheed Martin Skunk Works in California. The flight line refers to the space between the hangar and the runway . The aircraft is designed to demonstrate technology that will allow supersonic flight while reducing the sonic boom to a “quiet sonic thump, ” according to NASA. Front view of the X-59 aircraft. “ Sonic boom” refers to the sound that is associated with shock waves created when an object travels faster than the speed of sound . The sound that you hear when a whip is cracked is like a miniature version of the sonic boom. But the sonic boom of flights can generate massive amounts of energy, sounding like an explosion or a thunderclap . can also cause some damages to structures, like shattering glass and more . This...

10 lessons that we could learn from UKRAINE-RUSSIA WAR

  No two wars are alike . Studying the ongoing Russia-Ukraine conflict may, however, offer some insights as to its changing nature, the impact of new technologies and new dimensions of strategy. At least 10 military lessons can be enumerated. First, unstable deterrence upended by big-power geopolitical conflict is inherently escalatory . How well Russia fares on the battlefield remains key to the fate of Ukraine as an independent state and the future of NATO. Given the high stakes, all parties to the conflict are in escalation mode, with its consequential deeply worrying risks. Short of membership, NATO may double down on supporting Ukraine. Second, prolonged wars are more than stalemated wars due to their escalating aims . For some in our expert-community, long used to analysing American wars fought in easy combat environments, Russia’s ability to defy numerous predictions of its defeat has come as a surprise. Counting on Russia’s defeat has been a bad bet. Third, prolonged wars...
