Germany’s TUM Spots Rare Supernova to Measure Universe Expansion

German researchers at TUM, LMU, and Max Planck Institutes have captured a rare supernova that appears five times in the sky due to gravitational lensing. The discovery, nicknamed SN Winny, offers a new way to measure the universe’s expansion rate and could help resolve the long-standing Hubble tension between different measurement methods.

University of Florida Finds Why Antarctica Has Weakest Gravity

University of Florida scientists have solved the mystery of Antarctica’s “gravity hole”—a region where gravity is weaker than anywhere else on Earth. Using earthquake waves and computer models, they traced its formation back 70 million years. The research shows a connection between deep underground rock movements and the growth of Antarctica’s massive ice sheets.

SETI Institute Scientists Say Saturn’s Moon Titan Was Born from a Violent Moon Merger

Scientists at the SETI Institute have a new idea about Saturn’s giant moon Titan. It might have formed when two smaller moons crashed together and merged. The violent collision would explain Titan’s few craters, its strange orbit, and even the age of Saturn’s famous rings. NASA’s Dragonfly mission heading to Titan in 2034 could prove this theory right.

Europe’s ArianeGroup Prepares Ariane 64 Rocket for Historic Maiden Launch from French Guiana

ArianeGroup is set to launch the first four‑booster Ariane 64 on February 12, 2026, from French Guiana, deploying 32 Amazon Kuiper satellites. Twice as powerful as Ariane 62, the €4 billion program involves 13 ESA nations and 600 subcontractors. CTO Hervé Gilibert called it “something new for us on Ariane 6” as Europe challenges SpaceX with halved operating costs and a 30‑launch order book.
