The Euclid space telescope mission, which is being led with Swiss participation, has discovered the two oldest quasars ever observed.

Think of quasars as time machines. Rare but revealing. They are light from the beginnings of the universe that let astronomers investigate how early galaxies formed.

The Euclid space telescope mission, which is being led with Swiss participation, has discovered the two oldest quasars ever observed.

Astronomers using the Euclid telescope discovered ancient quasars, deepening the mystery of early universe evolution and massive cosmic structures.

Quasars — the brightest objects in the universe — are powered by supermassive black holes at the heart of early galaxies.

Seit Jahren arbeitet Euclid an einer gewaltigen Himmelskarte. Dabei findet das Weltraumteleskop auch mehr Quasare im frühen Universum als alle Geräte zuvor.
