Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles ...

An international team of astronomers using NASA's IXPE (Imaging X-ray Polarimetry Explorer), has challenged our understanding ...

Discover what happens when light collides with light. Explore the science behind photon-photon interaction, quantum ...

Particles known as tensor mesons are created when high-energy photons interact. These mesons have now been proposed to have a larger effect on photon behavior than previously thought, and provide a ...

Learn about the longest total lunar eclipse of 2025 and why the Blood Moon phenomenon occurs. We detail the U.S. eclipse ...

Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...

Singles become pairs: New insights into the light scattering of atoms Researchers at the Humboldt University of Berlin, partners of the DAALI project, have demonstrated a surprising effect present ...

As the Sun sets, this scattering effect is intensified. Now most of the Sun’s light is traveling through even more of the atmosphere and blue light is further scattered away, leaving the red and ...
