Quasars discovered by Euclid
This collage shows 15 of the 31 newly discovered quasars by the European Space Agency’s Euclid space telescope, with their names and redshift (z). Click on the circles around the quasars and above their names to zoom in.
Two of these giant, dazzling, black hole-powered galaxy cores are older than any we’ve seen before. These are visible on the first row, the first and second from the left.
The farthest quasar is named EUCL J172902.75+641018.1 (redshift of 7.77), and the second-farthest is named EUCL J125308.55+705432.3 (redshift of 7.69).
These cosmic elders shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.
[Image description: This collage with observations of the Euclid space telescope shows a grid of small, dark panels filled with tiny points and faint smudges of light. The lights vary in brightness and colour, including white, blue, yellow, and orange, with some appearing as dots and others as slightly blurred shapes. Each panel has a small label with letters and numbers at the bottom.]
