Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...

It's a glimpse into the universe's secret architecture, revealing how even the most subtle cosmic structures orchestrate the grand ballet of creation, guiding the destiny of galaxies across the eons.

This hypothesis has the advantage of explaining why the rings have a lot of ice and little rock, in contrast to models where a moon strayed inside Saturn’s Roche limit and was pulled apart.

This enormous chain of hundreds of galaxies—a cosmic filament—is twisting through space 400 million light-years away ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

NASA's new SPHEREx observatory has released its first all-sky cosmic map. This map uses 102 infrared wavelengths to reveal the universe in unprecedented detail. Scientists can now study cosmic ...

In this video, we delve into the Big Bang Theory, which explains the origin and expansion of the universe. This theory suggests that about 13.8 billion years ago, all matter and energy were ...

Discover seven unusual galaxies defying scientific predictions, from impossibly bright early universe objects to astrophysics ...

Inflation that’s roughly steady defied his critics’ expectations, because they had expected Trump’s high-tariff policy to send prices significantly higher. On the other hand, even steady inflation ...
