Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
Dark energy — an unknown energy source that is causing our Universe’s expansion to accelerate – doesn’t actually exist, according to new research.

New observations from the NASA/ESA/CSA James Webb Space Telescope confirms previous measurements by the NASA/ESA Hubble Space Telescope of distances between...
According to the prevailing inflationary universe theory, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of...
REBELS-25 existed as early as 700 million years after Big Bang, according to a paper published in the Monthly Notices of the Royal Astronomical Society.

The reionization of the Universe occurred some 500 to 900 million years after the Big Bang. It represents the transformation of neutral hydrogen into ionized...
The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected a small and vigorous black hole in GN-z11, an exceptionally luminous galaxy...
Observations of quasars reveal that many supermassive black holes were in place less than 700 million years after the Big Bang. However, the origin of...
In a new paper, astrophysicists from Australian National University present an overview of the thermal history of our Universe and the sequence of objects...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected linearly polarized thermal emission from dust grains in 9io9, a...
The Universe could be twice as old as current estimates, according to new research from the University of Ottawa that challenges the dominant cosmological...
Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...
Galaxies are strung along filaments in the vast cosmic web, which also contains enormous voids. Using the NASA/ESA/CSA James Webb Space Telescope, astronomers...
A fundamental consequence of the relativistic picture of expanding space is cosmological time dilation, where events in the distant Universe appear to...
Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from...
