๐ญ Euclid found 31 ancient quasars from the universe's first 770 million years โ including the oldest ever
ESA's Euclid telescope discovered 31 previously unknown quasars so distant we're seeing them as they were when the universe was less than 5% its current age. Two of the newly spotted giants shone with the light of a trillion suns when the cosmos was just 670 million years old โ now the oldest quasars ever observed. Euclid has only covered a fraction of its planned sky survey, so this could be just the start. What do you think these ancient supermassive black holes can reveal about how the first galaxies formed?
