A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...

A new idea about cosmic expansion has emerged that might remove the need for dark matter and dark energy altogether.

It drives the movements of stars and galaxies, but dark matter is invisible. While it remains a colossal mystery, a study ...

A paper published in 2024 theorizes that time may have existed before the Big Bang, but we're still not entirely sure.

Loeb recently made headlines with a paper submitted to the journal Astrobiology suggesting that just 15 million years after the Big Bang, the temperature from the cosmic background microwave ...

Most people assume that the Big Bang was the beginning of all things, but current scientific models point to another cosmic origin.

The Atacama Cosmology Telescope, or ACT, measured properties of the Big Bang’s thermal afterglow, known as the cosmic microwave background, with unprecedented sensitivity — particularly in the ...

Astronomers using the James Webb Space Telescope have discovered the most distant quiescent galaxy ever seen – one that had ...

A new theory challenges the standard model of cosmology, arguing that dark matter and dark energy are not the forces behind ...

Measurements of the faint afterglow of the Big Bang (known as the cosmic microwave background) are also important. They do not directly measure dark energy or how it evolves, but they provide ...

So far, nobody's been able to see past it to the Big Bang. As it turns out, astronomers are chipping away at that cosmic fog by using data from the Atacama Cosmology Telescope (ACT) in Chile.
