Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team. These so-called ...

A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies ...

Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA's James Webb Space Telescope is already providing new insights into this question. One of the ...

gravitational collapse of a cloud of hydrogen and helium some 100 times more massive than the sun. “Our modeling suggests that the first star may have condensed from a protogalactic cloud into a ...

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of ...

A team of researchers at the Institute of Astrophysics of the Canary Islands (IAC) has created a new simulation of early galaxy formation. The simulation allows us to get a fascinating, albeit brief ...

Twinkling like cosmic lighthouses on a shore 13 billion light-years from Earth, quasars are some of the oldest, brightest relics of the early universe that astronomers can detect today. Short for ...

We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from? But the universe would ...

The Big Bang theory has provided the most widely accepted basis of our understanding of the universe since it was first proposed by Georges Lemaitre in 1927. In short, it posits that all the matter in ...
