NASA's latest space telescope may up-end our entire model of the cosmos by taking a closer look at a shadowy phenomenon ...

Gravitational lensing often evokes images of a cosmic funhouse mirror: duplicated galaxies, dramatic arcs and distorted shapes. But the web-like, large-scale structure throughout the universe also ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

A new analysis of more than 1,700 supernovae is questioning whether the universe is really accelerating at all. After accounting for the ages of the stars that produce these explosions, researchers ...

Instead, they contribute to a residual energy of spacetime. Interestingly, this leftover contribution has the same mathematical form as the “cosmological constant”, or dark energy, which is making the ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster. However, new ...

Forget one Big Bang — try many. A bold new theory pokes holes in the popular origin story, suggesting the universe evolves through a series of lightning-fast bursts, rewriting what we know about ...

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent result reinforces it. Using the Dark Energy Spectroscopic Instrument, or ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

The MeerKAT radio telescope, composed of 64 dish antennas located in South Africa’s Northern Cape province, was built to ...

A vast structure seen more than 11 billion years ago reveals how clusters assembled from smaller clumps along the early ...

At a beachfront convention center in Cancún, Mexico, last December, Seshadri Nadathur presented a confidential growth chart of the universe. Seated in the audience, hundreds of his fellow scientists ...
