Dark matter could have helped make supermassive black holes in the early universe

It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out—a process that can take a billion years—and its core […]

NASA’s STS 115 Mission: When A UFO Prevented The Space Shuttle From Returning Home

One of the most fascinating UFO videos ever filmed by NASA was recorded during space shuttle Atlantis’ trip to the International Space Station in September of 2006.

During the 13-day mission, a number of mysterious objects were spotted by the Astronauts, and one in particular sighting caused Atlantis to delay […]

X-ray telescopes could also study exoplanets, say astronomers

Exoplanets are often discovered using the transit method (more than three-quarters of those discovered have been found this way.) The same transit technique can be used to study them, often revealing details about their atmosphere.

Geologists discover hidden magmatism at the Chang’e-6 lunar landing site

Lunar igneous activities, including intrusive and extrusive magmatism, and their products contain significant information about the lunar interior and its thermal state. Their distribution is asymmetrical on the nearside and farside, reflecting the global lunar dichotomy.

Astronomers discover new open cluster with Gaia

Using ESA’s Gaia satellite, astronomers have serendipitously discovered a new open cluster in the Milky Way galaxy. The newfound cluster, which received the designation Ash-1, is relatively young and consists of at least 400 member stars. The finding was reported in a research paper published August 21 on the pre-print server arXiv.

Reconfigurable sensor can detect particles 0.001 times the wavelength of light

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these innovations, non-Hermitian physics has emerged as a crucial area of research, offering new ways to manipulate light and enhance sensor sensitivity.

Scientists create ultracompact polarization-entangled photon sources for miniaturized quantum devices

Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and high-precision measurements. This light source is particularly small, pure, efficient, and versatile.

Physicists predict existence of new exciton type

Bruno Uchoa, a professor of condensed matter physics, and Hong-yi Xie, a postdoctoral fellow in condensed matter physics at the University of Oklahoma, have published research in the journal Proceedings of the National Academy of Sciences that predicts the existence of a new type of exciton. These particles could lead to the advancement of future […]

Research team develops atomic comagnetometer that suppresses noise by two orders of magnitude

A research team has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters. The team was led by Prof. Peng Xinhua and Associate Prof. Jiang Min from […]

Quantum nonlocality demonstrated in first loophole-free test of Hardy’s paradox

A research team has achieved the loophole-free test of Hardy’s paradox for the first time. The team successfully demonstrated Hardy’s nonlocality while closing both the detection efficiency loophole and the locality loophole.
