🌌 New simulations reveal the Milky Way is embedded in a massive, flat dark matter structure, not a symmetrical halo.

🤔 This finding may solve a decades-long mystery: why nearby galaxies recede slower than expected based on the Local Group's estimated mass.

✨ Published in Nature Astronomy (January 2026), the study led by Ewoud Wempe suggests this dark matter "sheet," tens of millions of light-years across, influences galactic motion.

💰 The Local Group's combined mass is estimated at 3.3 ± 0.6 trillion solar masses, but the larger sheet contains over four times more mass within 4 megaparsecs, impacting gravitational pull.

🌌 Hubble Telescope reveals the Milky Way devoured a dwarf galaxy just 2 billion years after the Big Bang, marking one of the earliest major mergers in our Galaxy's history.

⭐ This ancient merger, named Low-energy-Kraken-Heracles (LKH), occurred approximately 1.8 billion years before the previously known Gaia-Sausage-Enceladus merger, significantly impacting the Milky Way's early structure.

🔭 Astronomers analyzed globular clusters with Hubble, identifying LKH as a significant source of early galactic material and demonstrating that external galaxies played a crucial role in the Milky Way's formation.
