JWST Captures One-of-a-Kind Apep Triple Star System: A Cosmic Embryo Unreal in Dust
## Introduction The James Webb Space Telescope (JWST) has unveiled a stunning, “one-of-a-kind” image of a rare triple star system nicknamed Apep. Surrounded by nested, dusty spirals, this cosmic ensemble resembles an embryo cocooned in interstellar material. The image highlights JWST’s power to peer through dust that hides the most violent yet fascinating processes in…

New Theory of Universe Expansion May Upend How We Look at the Cosmos
Rethinking Standard Candles in Cosmology For decades, astronomers have relied on Type Ia supernovae as standard candles—cosmic beacons whose brightness helps measure distances across the expanding universe. This method underpins calculations of the Hubble constant, the rate at which the cosmos stretches. Yet recent work from researchers at Yonsei University in South Korea challenges a…

Hydrogen Bridge Between Dwarf Galaxies Unearthed in Virgo Cluster
Discovery of a Cosmic Gas Structure in Virgo In a discovery that reshapes our view of how galaxies exchange material, astronomers have identified a hydrogen bridge linking two dwarf galaxies in the Virgo Cluster. The stretch is made of neutral hydrogen and runs for about 156,000 light-years, connecting the galaxies and ending in a colossal…
