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

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.

  • 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.

  • 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 opens doors to Earth's atmospheric dynamics and those of planets like Venus and Mars.

As NASA's Glyn Collinson explained, "Any planet with an atmosphere should have an ambipolar field. Now that we've finally measured it, we can learn how it's shaped our planet and others over time."

"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...
