Astronomers Witness Supermassive Black Hole Awaken: A Cosmic Phenomenon Unfolds for the First Time

  In a breathtaking discovery, astronomers have captured the dramatic transformation of a supermassive black hole as it "wakes up" and begins to glow for the first time. This cosmic giant, located 300 million light-years away at the center of the galaxy SDSS1335+0728, has stunned the scientific community by transitioning from a dormant state to a highly active one, a process never observed in real time.

A supermassive black hole in galaxy SDSS1335+0728 has lit up. This could give astronomers a new look at how such celestial beasts awaken.

  • This groundbreaking observation, shared in the journal Astronomy and Astrophysics on June 18, 2024, sheds new light on the mysterious workings of active galactic nuclei (AGN)—the intensely bright cores of galaxies powered by supermassive black holes consuming vast amounts of matter. The findings could revolutionize our understanding of how these powerful cosmic engines ignite and evolve.
  • The awakening of this black hole was first detected in December 2019 by the Zwicky Transient Facility (ZTF) at California's Palomar Observatory. The galaxy suddenly brightened in visible light, surprising astronomers who had previously seen no signs of activity in this galaxy over the past 20 years. The sustained brightness over several years suggested that the black hole was transforming significantly.
  • In February 2024, NASA's Neil Gehrels Swift Observatory detected X-rays from the galaxy, further confirming the black hole's newfound activity. Scientists now believe they are witnessing the formation of an AGN in real time, a phenomenon that could offer unprecedented insights into how supermassive black holes grow and evolve.
  • Future observations, including those from NASA's James Webb Space Telescope and the upcoming Extremely Large Telescope in Chile, are expected to provide even more detailed data. This could help scientists understand the movement of gas around the black hole and uncover the secrets behind its sudden "awakening."

As astronomers continue exploring this fascinating event, the universe's hidden wonders are slowly unveiled, providing a glimpse into the extraordinary forces that shape galaxies and the cosmos.

India's Lunar Rover Finds Evidence of the Moon's Ancient Magma Ocean

Image
  In a breakthrough discovery, India's lunar rover " Pragyan " has unveiled evidence of the Moon's ancient global magma ocean . The findings, published in Nature by an Indian research team, mark the first-ever measurements from the Moon's polar highlands , broadening our understanding of the Moon's early history. The Pragyan rover’s wheels penetrated several centimeters into the lunar soil, allowing the rover’s APXS instrument to analyze the composition of the lunar regolith below the top surface layer. Credit: ISRO Around 4.5 billion years ago, a cataclysmic collision in the early solar system led to the formation of the Moon, which was once covered by a vast ocean of molten magma. This theory gained more robust backing after Pragyan's investigation of the rocks at the Vikram lander's site, now named "Point Shiv Shakti," located near the Moon's south pole. The rover analyzed samples using an Alpha Particle X-ray spectrometer (APXS),...

NASA's Groundbreaking Discovery: Invisible Electric Field Detected Around Earth for the First Time!

Image
In a groundbreaking discovery, NASA scientists have detected a weak yet vital energy field around Earth , the ambipolar electric field . Hypothesized over 60 years ago, this field was recently measured for the first time and could revolutionize our understanding of Earth's atmosphere, its evolution, and even life itself. Earth's North Pole, as seen by  Endurance . The streaks in the sky are from lens flare. ( NASA ) NASA's Endurance mission, launched in May 2022, successfully detected this invisible force at a high altitude of 768 kilometers. The field measured only 0.55 volts—equivalent to a watch battery—. Still, that tiny charge is powerful enough to launch hydrogen ions into space at supersonic speeds, contributing to the polar wind. Simulation This electric field, which balances the forces of gravity and charged particles in Earth's atmosphere, plays a crucial role in puffing up the ionosphere and allowing particles to escape into space. Understanding this field o...

"New Discovery: Galaxies Are Much Larger Than We Thought! First Images of Galactic Halo Unveil Surprising Details"

Image
  Galaxies Just Got Bigger! 🌌 Recent breakthroughs have unveiled something astonishing—galaxies, including our Milky Way, are far more extensive than previously thought! For the first time, astronomers have captured an image of the gas halo surrounding a galaxy, and it's a game-changer. This discovery shows that galaxies are not just clusters of stars but massive gas reservoirs extending much farther than imagined. The gas shroud around starburst galaxy IRAS 08339+6517. Credit: Cristy Roberts ANU/ASTRO 3D. Using the Keck Cosmic Web Imager in Hawai'i, scientists studied the galaxy IRAS 08339+6517, located 260 million light-years away. The new imaging reveals that its gas halo stretches to 100,000 light-years, dwarfing the stellar disc, which is just 7,800 light-years across. The study also indicates that the Milky Way already interacts with the Andromeda Galaxy, which lies just 2.5 million light-years away. Gas flows into galaxies along spiralling filaments. This image of a ga...
