The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field ...

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of ...

Star clusters are collections of thousands to millions of stars bound together by gravity — and many can be observed in the night sky with binoculars or a small telescope. One notable example is ω ...

For years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These efforts also help uncover how galaxies form and change over time. While most ...

The NASA/ESA Hubble Space Telescope has captured the first- ever picture of a distant quasar lensed into five images. In addition the image holds a treasure of lensed galaxies and even a supernova.

Astronomers have found something the universe wasn’t supposed to have: a galaxy cluster blazing with hot gas just 1.4 billion ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping. For over a ...

Two of the most prominent features in the image include the Thin One, highlighted in box A, and the Fishhook, a red swoosh highlighted in box B. Both are lensed background galaxies. The insets at ...

A new image of the galaxy cluster known as “El Gordo” is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image, taken by NASA’s James Webb ...
