Webb Telescope Detects Rotten Eggs Smell on Nearby Exoplanet

 The JWST (James Webb Space Telescope) has made a groundbreaking discovery by detecting the smell of rotten eggs on a nearby exoplanet, HD 189733. This "hot Jupiter," located just 13 times closer to its host star than Mercury, reveals an atmosphere filled with hydrogen sulfide, a compound responsible for the rotten odor.


  • The JWST's spectral analysis identified hydrogen sulfide and various other sulfur compounds. These findings are significant as sulfur is considered a building block of life, making it a prime target in the searching for habitable place. Despite its sterile conditions, temperatures soaring above 900°C, and 8,000 kph winds, HD 189733 offers valuable insights into exoplanet atmospheres.
  • The study, led by Guangwei Fu of John Hopkins University, highlighted the absence of methane in HD 189733's atmosphere, contrary to previous reports. Additionally, the exoplanet was found to have metals in its atmosphere, similar to stars.
  • The JWST continues to be a powerful tool for exoplanet research, providing detailed observations that help scientists understand planetary formation. HD 189733's atmosphere is a crucial baseline for future studies of other gas giants.

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...
