The discovery of 31 ancient quasars by the Euclid telescope in July 2026 is a groundbreaking achievement, offering a glimpse into the early universe and the mysteries of black holes. This remarkable find not only doubles the number of known quasars from that era but also shines a light on the immense power of these celestial objects. With redshifts of 7.77 and 7.69, these quasars are the earliest ever observed, dating back to the universe's infancy. Each of these cores radiated the equivalent of a trillion suns, despite the universe being only 5% of its current age. This raises intriguing questions about the formation and growth of these massive black holes, which weigh around a billion times the mass of the Sun. The Euclid telescope, primarily designed for mapping dark matter and energy, has proven its versatility in uncovering these rare and distant quasars, showcasing the potential for unexpected discoveries in space exploration. The challenge lies in understanding how these black holes accumulated such vast mass so quickly, a puzzle that continues to perplex astronomers and scientists alike.
