INBOX ASTRONOMY Hubble Solves Merger Mystery From Milky Way’s Early Years Release date: Monday, August 17, 2026 11:00:00 AM Eastern Daylight Time Astronomers find strong evidence for a massive merger 1.8 billion years earlier than the oldest previously known significant merger. The early universe was a chaotic place, crowded with young galaxies that smashed together and agglomerated into larger and larger galaxies over billions of years. Our own Milky Way experienced such collisions, but the details are dif ...Continue Reading
