To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe is gravitationally attracting all the other matter in the universe; ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

Many people wonder: if the universe is expanding, is there a point in space that serves as the “centre”? It seems intuitive to ask, how can something expand if there’s no specific starting point? The ...

Astronomers have discovered what could be the largest black hole ever detected. With a mass of 36 billion times that of our Sun, its gravity is so powerful that it bends the light of an entire galaxy ...

Our understanding of cosmology hinges on how well we know our own local universe, which remains poorly mapped and poorly ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...
