The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include ...

Stars form in regions of space known as stellar nurseries, where high concentrations of gas and dust coalesce to form a baby ...

"It is exhilarating to see 'galaxies' come out of our computer that look indistinguishable from the real thing." The post ...

New simulations show that early ultraviolet light controlled whether ultra-faint dwarf galaxies could form stars.

For years now, astronomers have been witnessing what seems like an ever-growing puzzle regarding the early formation of the ...

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 ...

Was planetary formation different during the early universe than today? This is what a recent study published in The Astrophysical Journal hopes to address as an international team of researchers ...

Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang. Astronomers have ...

Earlier this year, Euclid—a European telescope tasked to create the largest 3D map of the universe—sent back troves of cosmic data from deep space. Astronomers have since been hard at work picking ...

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.

Physicists predict that numerous 'defects' formed during the explosive expansion of the early universe. Now, a Korean research team has experimentally demonstrated for the first time in nearly 40 ...
