Euclid Telescope Uncovers Universe's Oldest Quasars, Rewriting Early Cosmic History

The European Space Agency (ESA) Euclid Space Telescope has made a groundbreaking discovery, spotting the oldest quasars ever observed, with two of them dating back to when the universe was just 670 million years old, a mere 5% of its current age. This record-breaking find of 31 ancient quasars by an international team of astronomers significantly deepens the mystery of how supermassive black holes grew so rapidly in the cosmos' infancy, challenging our current understanding of early galaxy formation. This unprecedented haul of ancient quasars is a 'game-changer' for astronomy, as the Euclid Space Telescope has already doubled the number of such objects known to science in just two years, far surpassing the capabilities of previous ground-based telescopes. The discovery pushes further into the Epoch of Reionisation, a critical period when the first stars and galaxies emerged, ionizing the universe's primordial hydrogen fog. The sheer size of these Supermassive Black Holes at such an early stage suggests they grew much faster than existing theories predict, leading scientists to re-evaluate the processes at play in the Early Universe. Astronomers will now use these observations to refine models of how galaxies and their central black holes co-evolved in the cosmic dawn. The Euclid Space Telescope, designed to map the Dark Universe, will continue its six-year mission, providing invaluable data that will also inform future missions like NASA Nancy Grace Roman Space Telescope. This ongoing exploration promises to unlock more secrets about the fundamental forces of Dark Energy and Dark Matter, ultimately helping humanity piece together the complete story of our universe's origins and evolution.
