Cosmic breakthrough uncovering evidence of low-frequency gravitational waves

More than two dozen researchers with ties to West Virginia University have helped unearth evidence of ripples in spacetime that have never been observed before now. Gravitational waves travel outwards…

New method to measure cosmic expansion

In 1929, astronomers discovered that galaxies are streaming away from us and each other. They interpreted this observation that the universe is expanding. However, when they measured how fast it…

NASA’s Parker Solar Probe completes 16th close approach to the Sun

NASA’s Parker Solar Probe accomplished a milestone on June 27, 2023 – its 16th orbit of the Sun. This included a close approach to the Sun (known as perihelion) on June…

First direct visualization of a zero-field pair density wave

Tunneling spectroscopy uncovers the clearest proof yet that this exotic superconducting state of matter exists without a magnetic field in an iron-based superconductor. In the field of superconductivity—the phenomenon in…

New single-photon Raman lidar can monitor for underwater oil leaks

System could be used aboard underwater vehicles for many applications. Researchers report a new single-photon Raman lidar system that operates underwater and can remotely distinguish various substances. They also show…

Breakthrough in the search for slowly oscillating gravitational waves

For the first time, astrophysicists have found compelling evidence for the existence of gravitational waves which oscillate with periods ranging from years to decades. For this, the researchers evaluated data…
