Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between galaxies that had remained otherwise hidden in previous surveys.

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 ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

New data from the South Pole Telescope indicates that the birth of the first massive galaxies that lit up the early universe was an explosive event, happening faster and ending sooner than suspected.

What if everything scientists ever thought about the universe’s earliest chemical reactions was wrong? Recent tests have turned decades of theory on its head, showing that the first molecular ...

Stars form in regions of space known as stellar nurseries, where high concentrations of gas and dust coalesce to form a baby star. Also called molecular clouds, these regions of space can be massive, ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

Stephen Hawking once argued that perfection does not exist in the universe. Surprisingly, he said our very existence depends ...
