Quasars — the brightest objects in the universe — are powered by supermassive black holes at the heart of early galaxies.

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary averting a cosmological crisis, according to new research.

Researchers confirm the universe's expansion is still accelerating, challenging previous claims of dark energy weakening and halting this growth.

Taking a fresh look at data involving a specific type of stellar explosion, a team of researchers says it has confirmed the long-accepted notion that the universe is expanding at ​an accelerated rate ...

Mathematicians from the University of California, Davis, are challenging the idea that dark energy is responsible for the accelerating expansion of the universe also known as cosmic expansion In a ...
