The clearest and most precise images yet of the universe in its infancy—the earliest cosmic time accessible to humans—have been produced by an international team of astronomers.

Measuring light, known as the cosmic microwave background (CMB), that traveled for more than 13 billion years to reach a telescope high in the Chilean Andes, the new images reveal the universe when it was about 380,000 years old—the equivalent of hours-old baby pictures of a now middle-aged cosmos.

The research, by the Atacama Cosmology Telescope (ACT) collaboration, shows both the intensity and polarization of the earliest light after the Big Bang with unprecedented clarity, revealing the formation of ancient, consolidating clouds of hydrogen and helium that later developed into the first stars an...

A terrifying glimpse at one potential fate of our Milky Way galaxy has come to light thanks to the discovery of a cosmic anomaly that challenges our understanding of the universe.

An international team of astronomers led by CHRIST University, Bangalore, found that a massive spiral galaxy almost 1 billion light-years away from Earth harbors a supermassive black hole billions of times the sun’s mass which is powering colossal radio jets stretching 6 million light-years across.

That is one o...

Two different teams of astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. The discovery, reported in two separate studies, was made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early universe.

Discovered last year, JADES-GS-z14-0 is the most distant confirmed galaxy ever found: it is so far away, its light took 13.4 billion years to reach us, meaning we see it as it was when the universe was less than 300 million years old, about 2% of its present age.

The new oxygen detection with ALMA, a telescope array in Chile’s Atacama Desert, suggests the galaxy is much m...
