New maps from the Planck satellite uncover the ‘polarised’ light from the early Universe across the entire sky, revealing that the first stars formed much later than previously thought.

Astronomers have been able to peer back to the young Universe to determine how quasars – powered by supermassive black holes with the mass of a billion suns – form and shape the evolution of galaxies.

Satellite’s first all-sky image is the most detailed picture to date of the early Universe, giving us a better understanding of its birth.

Evidence of an intense warming period in the Universe’s early history, described as a form of “cosmic climate change”, has been found by an international team of astronomers.

Scientists at Cambridge’s Kavli Institute are studying how the Universe developed after the Big Bang by analysing light emitted up to 13.7 billion years ago.
