Euclid Telescope Unveils Two Ancient Quasars Among the Oldest Objects in the Universe

The European Space Agency's (ESA) Euclid Space Telescope has made a groundbreaking discovery by identifying over two dozen ancient quasars among the oldest and most distant objects ever observed. This includes 31 massive celestial bodies, with two dating back to when the universe was just 5% of its current age. These findings, detailed in a study published in Astronomy & Astrophysics, provide unprecedented insights into the early stages of galaxy formation and the dynamics of ancient supermassive black holes.

Quasars are among the brightest objects in the cosmos, emitting extraordinary amounts of energy due to the intense friction generated as matter spirals into supermassive black holes. Despite their luminosity, these distant quasars were challenging for astronomers to detect because their light has traveled over 13 billion years to reach Earth, making them extremely faint and difficult to distinguish from surrounding stars.

Among the newly discovered quasars are a dozen that existed within the first 770 million years after the Big Bang. Two of these ancient objects formed just 670 million years post-Big Bang, placing them among the oldest known celestial bodies. This discovery could help unravel mysteries such as how supermassive black holes grew so rapidly in the early universe and provide new insights into galaxy formation during this critical period.

The Euclid mission's findings are crucial for mapping billions of galaxies and understanding dark energy, a mysterious force believed to be causing the accelerating expansion of the cosmos. These observations could also shape future research by NASA’s Nancy Grace Roman Space Telescope, which aims to continue exploring the nature of dark energy and the universe at large scales.
