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 ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

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.

As its first image, the James Webb Space Telescope (JWST) revealed the deepest infrared image of the universe to date. The image is teeming with thousands of galaxies, including some from when the ...

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 ...
