Mysterious little red dots threatened to overhaul modern cosmology—but new research may have solved the celestial conundrum.

Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not ...

Researchers studied how the universe’s structure changed over time. They found that the universe is less clumpy than expected ...

"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs." ...

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that ...

Observations from the James Webb Space Telescope reveal monster black holes in the early universe that seem to have grown too ...

Early data of “little red dots,” or LRDs, from the James Webb Space Telescope (JWST) appeared to suggest the presence of galaxies too massive to exist in our modern cosmological models.

By employing a new and improved supercollider, scientists are hoping to dissect the very fabric of the Universe and calculate ...

Over the past decade, cosmology has been embroiled in a growing ... microwave static produced just 380,000 years after the Big Bang. As Cepheids get brighter, they pulsate more slowly, enabling ...

these objects represented some of the earliest light ever glimpsed by humanity—originating from between 600 million and 1.5 billion years after the Big Bang. There was just one problem ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
