New research suggests that water-rich worlds could have formed just 300 million years after the Big Bang, potentially pushing back the timeline for life. New evidence suggests that the essential chemical ingredients for life may have permeated the...

Astronomers spot UV radiation from galaxy MXDFz4.4, just 1.4 billion years after the Big Bang, reshaping ideas about the early universe. Astronomers have captured the first clear signature of ionizing radiation leaking from a galaxy that lived at the...

alone. Webb’s view of the GOODS-North field highlights GN-z11, a galaxy observed just 430 million years after the Big Bang. Its compact central source shows evidence consistent with an actively feeding black hole. Credit: NASA / ESA / CSA Calculating...

in observational cosmology, pinning down the abundance of primordial helium created in the immediate aftermath of the Big Bang with unprecedented precision. By reducing the uncertainty of this fundamental value to just 0.5%, the study offers a powerful...

even lighter-weight collisions can mimic the extreme environmental conditions that existed in the moments following the Big Bang. Historically, the production of quark-gluon plasma (QGP) in particle accelerators has required the collision of heavy...

New research reveals that enough material to form several Earth-sized planets existed shortly after the Big Bang, defying previous cosmic timelines. New computational models indicate that the fundamental building blocks required for Earth-like planets...

New study of quark‑gluon plasma at the LHC uncovers fresh insights into the primordial matter that existed just after the Big Bang. Researchers operating the Large Hadron Collider (LHC) have captured fresh insights into the infant universe by tracking...

results reveal the early universe’s exotic matter state, giving scientists a rare glimpse into conditions right after the Big Bang. Scientists are closing in on the elusive conditions that prevailed a fraction of a second after the universe burst into...

have traced the most distant fast radio burst ever recorded to a strange, young dwarf galaxy 3 billion years after the Big Bang. Astronomers have traced a fleeting radio flash to a surprisingly humble origin. Utilizing the advanced observational power...

direct evidence of how the first generations of galaxies helped re‑ionize the cosmos merely 1.4 billion years after the Big Bang. The results appear in the Astrophysical Journal and shed fresh light on the so‑called cosmic reionization era. A Minuscule...

oxygen, and silicon in gas associated with three galaxies dating back to within several hundred million years of the Big Bang, indicating that the cosmic process of spreading heavy elements began almost immediately after the first stars ignited. The...

galaxy observed at redshift z = 5.0167. The galaxy, known as J0148‑4214, dates to roughly 1.2 billion years after the Big Bang, offering a rare glimpse of multiple heavyweight black holes co‑existing at such an early epoch. The discovery was made...

Astronomers discover a black hole wrapped in dense hydrogen 660 Myr after the Big Bang, shedding light on JWST’s red dots and rapid black‑hole growth. Observations with the James Webb Space Telescope have turned a faint point of light known as...

star-forming gas in four galaxies from the early Universe, offering a new glimpse into how galaxies grew after the Big Bang. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have achieved a milestone in early-universe astronomy...

a galaxy, showing that intricate galactic architectures were already taking shape merely 4.5 billion years after the Big Bang. The result, detailed in Monthly Notices of the Royal Astronomical Society, offers fresh insight into the organization of...

Euclid discovers 31 ancient quasars, including two from 670 million years after the Big Bang, shedding light on early black holes and galaxy formation. The ESA Euclid mission has added 31 previously unknown quasars to the cosmic record, among them two...

Newly found object 660 million years post‑Big Bang could explain the rapid growth of the universe’s earliest supermassive black holes. A team of astronomers has reported what may represent the earliest example of a “black‑hole star,” a compact system...

originated from a colossal explosion that took place during the universe’s infancy, less than a billion years after the Big Bang. Swift global coordination among space-based and ground-based observatories allowed astronomers to pinpoint the event, now...

signatures. The analysis revealed a population of stars approximately 13 billion years old—nearly as ancient as the Big Bang itself. These findings were later corroborated by historical data from the Dark Energy Camera on the NSF Victor M. Blanco...

generated quark-gluon plasma, a primordial state of matter that characterized the cosmos just microseconds after the Big Bang. The team is working to map the equation of state for nuclear matter—essentially a fundamental rulebook detailing how...
